576SECTION 1.0 DESCRIPTION1.1 GeneralCongratulations on your
purchase of a Siemens ELMO-PackTM oil sealed liquid ringvacuum
system.By carefully following the procedures outlined in this
manual forinstallation and operation of your system, you will
guarantee years of satisfactory systemperformance.The ELMO-Pack TM
Oil Seal System is a liquid ring vacuum pump package with a
self-contained cooling system. The system is designed to operate
with a low viscosity sealingoil that is provided with the system.
This oil will provide increased vacuum levels(deeper vacuum) at
increased operating temperatures. The pump can operate at a
highertemperature without cavitation and without loss of operating
liquid due to evaporationbecause oil has a much lower vapor
pressure and higher boiling point than water. Normaloperating
temperature for the system is 150 -190F.The ELMO-Pack TM systems
are available in a variety of sizes.They can be provided ina
standard SIMPLEX configuration or an EXPANDABLE configuration.1.2
Operating PrinciplesThe ELMO-Pack TM oil seal liquid ring pump uses
proven liquid ring technology toprovide a reliable mechanical
vacuum system. The liquid ring pump is the most importantcomponent
in the system.A rotating impeller is used to make the operating oil
flowaround the inside of the pump casing.The oil forms a seal
between the impeller blades,port plates and casing.The gas is
compressed in this sealed chamber.Because heat is generated during
the compression, the discharge of the pump is hotterthan the
suction.The operating oil absorbs most of the heat.Since the oil
and inlet gas(usually air) are mixed at the discharge, it is
necessary to separate the two prior todischarging the gas to the
atmosphere.To do this, a borosilicate gas coalescing filter
isplaced in the discharge, which removes all of the visible oil
from the gas beforedischarging.The filter is located in the upper
portion of the discharge separator vessel.This vessel is large
enough to hold about two minutes of oil supply, which is
recirculatedback to the vacuum pump.The discharged oil is hot and
must be cooled during normal operation by passing througha
cooler.At start-up, however, the extra oil in the separator is
relatively cool (roomtemperature).Since any water vapor in the
suction stream could condense if thedischarge is too cool, it is
desirable to heat the oil quickly.Therefore, a thermal bypassvalve
is placed in the oil re-circulation line.This valve lets the oil
bypass the cooler untilit gets to about 150F.Once it reaches 150F,
the valve mechanically switches and theoil is passed through the
cooler.7The cooler is designed to remove the thermal load, about
equal to the motor horsepower,from the oil before it is sucked back
into the pump.Since the cooler uses ambient air tooperate, the oil
discharge temperature will be somewhat dependent on the local
airdensity and temperature.CAUTIONOperating the system at altitudes
above 3000 feet or more maycause discharge temperatures to be above
therecommended maximum unless specially designed coolers are
utilized.CAUTIONDo not operate the system in a closed room.Adequate
ventilation is required to ensure proper operation.CAUTIONOperation
of the system in ambienttemperatures greater than 104 F is not
recommended.89Each system contains the following components
described below.Refer to Figure 1-1 for relativeplacement in the
systems.1.2.1 Siemens liquid ring vacuum pump.The Siemens liquid
ring vacuum pump is the heart of the system. A liquid ring
vacuumpump is a non-pulsating rotary vacuum pump that compresses
gasses using liquid as acompressing medium. The Siemens liquid ring
vacuum pump has a simple design forreliability. A single moving
part, the impeller, rotates forcing the operating liquid to forma
liquid ring within the casing. This liquid acts as a sealant, as a
compressing media andas a coolant.Wear is minimized because there
is no mechanical contact of moving parts.On the suction cycle,
liquid recedes from the impellers hub, drawing gas to becompressed
through the axial suction port.Because the impeller is off-center
to the ringof rotating liquid, the liquid reciprocates into spaces
between the blades much like theoperation of a cylinder,
compressing the gas against the hub. After almost one
revolution,the compressed gas is discharged through axial discharge
ports.The Siemens variabledischarge port provides maximum
efficiency at different vacuum levels.CAUTIONOn initial start up of
the system, be sure to place the recommended (See Table 2-1)
priming oil in the pump.This isin addition to the oil placed in the
separator.Damage to thesystem is possible if this oil is not added
on initial start-up.1.2.2 Electric MotorThe electric motor provides
an efficient, reliable prime mover for the pump. A variety ofmotor
designs can be provided including explosion proof motors and motors
for a varietyof voltages. The correct motor voltage must be
specified and is the responsibility of theuser.1.2.3 Air / Oil
SeparatorThe liquid ring pump discharges both oil and air into a
special discharge separator. Theseparator is designed to separate
the oil from the air. The oil is separated and settles to thebottom
of the separator tank where it is returned to the pump through the
cooling system.The air is discharged through a fitting located at
the top of the separator. The separatoralso has a port for
convenient filling of the system.CAUTIONDo not fill the system
through the discharge gas fitting.Use the oil fill port on the side
of the separator.101.2.4 Coalescing FilterThe separator also has a
replaceable internal coalescing filter. The air being vented
toatmosphere must first pass through this filter. Almost all of the
oil mist (99.97% of allparticles 0.3 microns or larger) is removed
from the air stream and returned to the system.1.2.5 Heat
ExchangerThe oil temperature is maintained by an air to oil heat
exchanger with a motor driven fanand a thermal bypass valve.The
heat exchanger fan motor passes ambient air over theradiator style
heat exchanger and operates continuously. This cooling system is
designedto operate in ambient temperatures up to 104F at altitudes
of less than 3000 feet abovemean sea level.1.2.6 Inlet Check
ValveThe inlet check valve provides a tight shut off and prolonged
cycle life utilizing a uniquecontinuous elastomer around the valve
bore.1.2.7 Inlet Vacuum GaugeThe inlet vacuum gauge is a bourdon
tube type gauge and indicates the vacuum level atthe pump inlet
relative to ambient pressure in inches Hg vacuum.The gauge is
isolatedwith a convenient gauge cock to allow removal or
replacement without affecting systemoperation.1.2.8 High
Temperature SwitchA discharge temperature switch is provided to
protect the pump from a high temperaturecondition. This switch has
common and normally open contacts. This switch must be tiedinto the
motor control panel. A high temperature condition will shut down
the vacuumsystem. A high temperature condition can result in damage
to the pump. The switch tripsat a temperature of approximately
200F.CAUTIONDo not operate the vacuum system unless thedischarge
high temperature switch is connected.Operation at excessive
temperaturescould damage the pump orcause early or excessive system
wear.111.2.9 Thermal Bypass ValveThe oil temperature is maintained
by an air to oil heat exchanger with a motor driven fanand a
thermal bypass valve. The thermal bypass valve is a
temperature-actuated valvethat allows the service oil to bypass the
heat exchanger when its temperature is below150F.This cooling
system is designed to operate in ambient temperatures up to
104F.1.2.10 Compound GaugeThe operating liquid compound pressure
gauge provides the user an easy check to assurethat the oil system
is running properly. This gauge should normally read a slight
vacuum(1-8Hg Vacuum).The gauge is isolated with a gauge cock to
provide removal orreplacement without affecting system
operation.1.2.11 Pressure GaugeThe separator has a discharge
pressure gauge located near the top of the separator. If thefilter
becomes obstructed this gauge will indicate a high back-pressure.
Normal range is 1to 3 psig.CAUTIONDo not operate the pump with a
high discharge back pressuresince this will cause the motor to draw
excessive power.1.2.12 Oil Level GaugeA separator level gauge
provides easy monitoring of the system oil level. The oil
levelshould be at the pump shaft centerline for Siemens model 2BE
vacuum pumps (30 to 75Horsepower) and approximately even with the
centerline of the operating liquid inletconnection on the pump for
Siemens model 2AV or 2BV (1.5 to 25 Horsepower) vacuumpumps.1.2.13
Drain ValveThe separator is equipped with a separator drain valve.
This will allow the user to drainaway water that may have collected
in the system from the process and to drain the oil formaintenance
and/or changing. Water will eventually settle to the bottom of the
separatortank. The drain line is connected to the bottom of the
separator tank for convenientdraining.1.2.14 Gauge CocksGauge cocks
are provided with pressure gauges (items 7 & 10) to provide
isolation of thegauges for easy replacement or removal without
affecting system operation.121.2.15 Structural steel BaseA rugged
structural steel base is provided with the system. When a
non-expandablesimplex system is furnished, all equipment is
supplied on one base. When an expandablesystem (simplex, duplex or
triplex) is furnished, the control panel and a vacuum receivertank
are furnished on a separate base, with each pump system on its own
base.CAUTIONThe system should be installed on a flat, level
surface.If anchored to the surface with bolts, take care in
avoiding excessivepiping stress on the pump, which could cause
leaks or vibration during operation.1.2.16 Temperature GaugeA
discharge temperature gauge is provided to indicate the operating
temperature of thesystem. The acceptable range is 150F to
190F.1.2.17 Ball ValvesThe Y-strainer can be cleaned without loss
of oil by closing two isolation valves locatedat each end of the
strainer. These valves should be fully opened during
normaloperation.WARNINGDo not operate the system without oil or
with any of the oil systemvalves in the closed position as severe
damage can result.1.2.18 Y-StrainerThe oil is collected in the
bottom of the separator and returned to the pump after
passingthrough a Y-Strainer and the heat exchanger.The Y-Strainer
is in the system to removeany foreign debris that may have been
introduced from the users process.1.2.19 Sight Flow IndicatorA
scavenge line is provided from the bottom of the coalescing filter
to the suction port ofthe liquid ring vacuum pump. This will remove
any oil that has collected in the bottom ofthe filter. The line
runs externally from the upper portion of the separator tank
(whichcontains the coalescing filter) to the inlet manifold on the
pump.A sight flow indicator is13provided in this line. It is normal
for a SLIGHT amount of oil to flow in this line.Aconstant flow of
oil indicates that the coalescing filter requires replacement.[Note
that asmall needle valve is included in high vacuum systems to
allow operation above 28inches Hg vacuum.]1.2.20 Low Level Switch
(optional)A separator low-level switch may be provided to indicate
a low oil level condition. Thisswitch has common and normally open
contacts, which should be tied into the motorcontrol panel using a
time delay to eliminate false trips due to tank turbulance. A
low-level condition should shut down the pump drive motor.Low oil
level can result in lossof the liquid ring and possible damage to
the pump.1.2.21 High Level Switch (optional)A separator high-level
switch may be provided to indicate a high oil level condition.
Thisswitch has common and normally open contacts, which should be
tied into the motorcontrol panel using a time delay to eliminate
false trips due to tank turbulance. A high-level condition should
shut down the pump drive motor.High oil level can result inmotor
overload and possible damage to the pump.1.2.22 Inlet Filter
(optional)An inlet filter with 10-micron polyester element may be
provided for applications whereparticulate matter may be present in
the users process.1.2.23 Non-Expandible Control Panel
(optional)1.2.23.1 Control Panel (optional)The optional base-frame
mounted integral control panel is provided with motor
starterincluding overloads, on-off switch, motor running light,
high temperature light andhigh/low-level indicator lights. A reset
switch is provided to clear any shut downcondition. The panel will
automatically shut down the pump drive motor in the event
ofover-temperature, low or high oil level (if supplied with the
system) or motor overloadconditions. The indicator lights will show
the reason for shut down. The panel has anhour meter that will
indicate total running hours for the pump drive motor.The panel
provides motor protection that will prevent motor burn out in
overloadconditions. The operator should limit the number of across
the line starts. This is toprevent potential motor damage from
excessive starting. All electric motors require highstarting
current and the number of starts per hour should be limited to the
motormanufacturers recommendations (usually one hot or 2 cold
starts per hour).The panel can be provided dedicated for one system
(simplex) or can be ordered for anexpandable system.14CAUTIONThe
non-expandable system panel does notcontrol the system vacuum
level.If system vacuum level control is required,an expandable
panel with PLC control is required.The non-expandable simplex
control panel will be provided attached to the standardstructural
base fame that accommodates the system.1.2.23.2 Power SupplyThe
panel has been designed for the voltage indicated on the supplied
panel-wiringdiagram.CAUTIONOperation of this system at
voltagesother than those specified in thesupplied system
documentationcan cause extreme damage.1.2.23.3
Combination/Non-Combination Starter PanelSiemens panels are
non-combination types unless otherwise specified.The customer must
provide a fusible disconnect or circuit breaker unless a
combinationstarter is specified for the control panel.151.2.23.4

resultin improper motor protection. The settings should be checked
to assure that they matchthe motor full load current value that is
provided on the motor nameplates.161.2.23.5 Non-expandable control
panel sequence of operationThe pump starts when the operator places
the on-off switch in the ON position.Thepump will run continuously
unless an alarm condition occurs.If the pump shuts downthe panel
will display the alarm condition that caused the shutdown by
illuminating theappropriate indicator light. This alarm light will
stay on and the pump will stay de-energized until the user presses
the RESET Pushbutton.When the RESET button ispressed, the pump will
re-start unless an alarm condition is still present.If the
pumpshuts down and none of the alarm indicator lights are
illuminated, the motor overloadcould be tripped due to a motor
overload condition. The motor overload relays have amanual reset
button, which must be actuated to allow the motor to
re-start.CAUTIONWhen the panel is connected to the users power
supply, assure that theproper voltage is applied.Refer to the
wiring diagram furnished withthe system.CAUTIONThe user must
provide required primary circuit protection disconnectin compliance
with NEC and local codes.This may be a fusibledisonnect or circuit
breaker.CAUTIONOnly qualified personnelShould attempt to work on
the control panel.Dangerous voltages are present.17181.3 Expandable
SystemsAll ELMO-Pack TMoil seal liquid ring vacuum systems are also
available as expandablesystems in either NFPA99 (National Fire
Protection Association Standard for HospitalSystems) or Siemens
Standard configurations.Expandable systems are available as
simplex, duplex or triplex configurations from thefactory.The
expandable panel can be ordered set up to handle up to three
pumps.The panel ispre-configured for operation as a triplex system,
so any expandable simplex or duplexpanel can be easily upgraded to
handle additional pumps.CAUTIONModification of the Siemens
panelshould only be attempted by a qualified electricianand done
per manufacturers instructions.1.3.1 DescriptionThe expandable
system consists of one or more simplex systems as previously
describedplus an additional base frame containing a vacuum receiver
tank and an expandablecontrol panel. Each vacuum pump system will
be referred to as an Expansion Module.The system can handle up to
three Expansion Modules.If it is initially ordered with oneor two
pumps, additional ELMO-Pack TM Expansion Modules can be added later
andfield installed.The additional electrical components can be
field installed in theExpandable Control Panel by a qualified
electrician and are included with each expansionmodule.The panel is
pre-wired and designed to accept the expansion modulecomponents.A
qualified plumber can pipe the additional expansion modules into
thesystem.The panel is normally furnished in a NEMA 12 or NEMA 7
enclosure with non-combination starters. The customer must provide
a fusible disconnect or circuit breaker.A normal NFPA 99 system
includes disconnects.The Vacuum receiver tank is included to
provide vacuum storage to accommodatechanges in demand from the
customers process. The vacuum receiver is a Carbon steelASME code
vessel that functions as an accumulator. If there are sudden
changes indemand from the process, the vacuum receiver volume will
respond by providing a storedvacuum source that will help maintain
the system pressure.This will prevent excessivestarting and
stopping of the pumps.The receiver tank is provided with a sight
levelgauge and drain valve.191.3.2 NFPA vs. Standard SystemsThe
expandable ELMO-Pack TM liquid ring systems are available as either
standardconfiguration or NFPA 99 compliant systems.Both the

Set at 22 inches Hg vacuumTR-1 Time Delay Relay (user
adjustable)23Refer to Table 1-2 for panel configuration.The heat
exchanger fan and vacuum pump drive motors are protected by
thermaloverload devices. Each overload relay has an adjustable
setting that is factory set tomatch the nameplate full load current
of the motors. If the setting is changed it will resultin improper
motor protection. The settings should be checked to assure that
they matchthe motor full load current value that is provided on the
motor nameplates.1.3.2.2 Operation (25 HP or less)CAUTIONWhen the
panel is connected to the users power supply, assure that theproper
voltage is applied. Refer to wiring diagram furnished with
thesystem.CAUTIONFor non-NFPA 99 systems, the user must provide a
primary circuitprotection disconnect in compliance with NEC. This
may be a fusibledisconnect or circuit breaker.These are provided
per NFPA 99requirements on NFPA systems.The Expandable Control
Panel provides manual or automatic operation of one, two orthree
pumps. The requirement for running pumps is determined by vacuum
switches.Ifthe system has three pumps and all three units are in
the automatic mode position, thesystem will operate as follows: On
start-up, all three pumps will be started immediatelyand will
continue to run until vacuum increases beyond the set-point of
VAC-1 vacuumswitch. This switch is set to the highest vacuum of all
three switches. We will refer to thisswitch as the lead vacuum
switch.When vacuum increases beyond the lead vacuumswitch set
point, all pumps will shut down after a user adjustable time delay
has timedout.The time delay prevents overheating of the motors
caused by excessive repeatedstarts.System vaccum will decrease with
process demand.When system vacuum decreases tothe set point plus
the adjustable dead band of the lead vacuum switch (VAC-1), the
leadpump will start. This pump will continue to run until process
vacuum has reached the setpoint of the lead vacuum switch and the
adjustable run timer TR-1 has timed out.If system vacuum decreases
with only one pump running and reaches the set point ofVAC-2
(lagvacuum switch), the lag pump will start. Both pumps will
continue to rununtil the system vacuum has reached the set point of
the lead pressure switch and theadjustable run timer TR-1 has timed
out.24If system vacuum continues to decrease with two pumps running
and reaches the setpoint of VAC-3 (lag-lagvacuum switch), the
lag-lag pump will start.All three pumpswill continue to run until
the system vacuum has reached the set point of the lead
pressureswitch and the adjustable run timer TR-1 has timed out.Each
time the lead vacuum switch shuts down the pumps (on increasing
vacuum), theroles of lead, lag and lag-lag pump functions will be
alternated between pump #1,pump #2 and pump #3 to provide even
cycle time for all three pumps.If one pump isshut down because of
an alarm condition, the other pumps will continue to run ondemand
as described above.CAUTIONOnly qualified personnelShould attempt to
work on the control panel.Dangerous voltages are present.1.3.2.3
Operation (30 HP or larger)System panel configuration logic is
custom designed for larger horsepower units to meetcustomer
requirements.Please refer to the custom documentation included with
yourlarge horsepower system for specific details of operation.1.4
Application LimitsThe ELMO-Pack TM Oil Seal System is a liquid ring
vacuum pump package with a self-contained cooling system. The
system is designed to operate with a special sealing oilthat is
provided with the system. This oil will provide increased vacuum
levels (deepervacuum) at increased operating temperatures. The pump
can operate at a highertemperature without cavitation, and there
will not be loss of operating liquid due toevaporation because oil
has a much lower vapor pressure (higher boiling point) thanwater.
Normal operating temperature for the system is 150 -190F.These
systems are ideal where it is not convenient for a user to provide
a water supply toa typical liquid ring pump application.25Liquid
ring pumps are ideal for applications requiring a rugged vacuum
pump that cantolerate entrained liquid and solids.However, there
are some situations that requirespecial designs.If the following
limits are observed, the standard system will give yearsof trouble
free operation.-Ambient Temperature must not exceed 104F while
using the standard motors.-Altitude at installation location must
be 3000 ft. above mean sea level.-Water vapor or the condensable
load must not be excessive.Contact the factoryfor assistance in
determining if excessive vapor is present in your suction gas.-The
use of an inlet filter is advisable if particulate matter is
present in the suctionstream.This will prolong the life of the
oil.-If reactive chemicals are present, special oils may be
required.The standard oil isan ISO 22 non-detergent semi-synthetic
(Poly-alpha olefin) oil selected forvacuum service.Contact the
factory for assistance in selecting the proper oil foryour
application.-Liquid ring pumps may not operate properly below 29
inches Hg vacuum.Ifexcessive vibration or noise at low pressures is
experienced, contact the factoryfor assistance.-Maximum consumed
power is at 20 inches Hg vacuum.It may be necessary toadjust the
seal liquid flow rate at this operating point by throttling one of
thestrainer isolation valves.-Operation of the system in dirty or
dusty environments may require frequentcleaning of the radiator
cooler.It is also possible to provide an air duct or filter
tominimize fouling of the radiator.WARNINGOperation of the standard
system outside the application limitsdescribed above could cause a
hazardous condition,damage to the equipment and will void the
factory warranty.26Section 2.0 Installation2.1 UnpackingInspect the
ELMO-Pack TM System and pump carefully and note any signs of
damageincurred in transit. Verify that the packing list and the
received shipment are in agreementand all listed items are
present.Since all systems are ordinarily shipped FOB our factory,
any damages in transit are theresponsibility of the carrier and
should be reported to them immediately. All ELMO-PackTM Systems can
be lifted using a forklift on the underside of the steel frame.
Never liftthe entire system by the pump and motor assembly
only.When lifting, care should betaken to assure that the skid is
secure and balanced.The skid can then be lowered ontowooden
cribbing (4x4 timbers are suitable) so the forks can be
withdrawn.The base should be lowered and leveled using
jacks.Precision leveling is not required;level the base using a
carpenters level.Although grouting is not required, the frameshould
be continuously supported.The frame is provided with anchor bolt
holes tosecure the system to the foundation.For maintenance, the
Siemens vacuum pump and motor assembly can be lifted off of
thesystems frame independently. See Maintenance section for lifting
instructions. The inletport of the pump is covered for shipment as
well as the exhaust connection on theseparator tank. This will
prevent dirt or other foreign materials from entering the pump
orseparator. Leave these covers in place until just before the
piping is connected to theELMO-PackTM System.2.2 Electrical Power
SupplyCheck the wiring diagram supplied with your system to
determine the voltagerequirements for the unit and the type of
disconnects supplied.WARNINGIf the voltage reported on the wiring
diagram supplied with the systemdoes not match your supply
voltage,contact the factory immediately.Do not attempt to install
the system if the supply voltage and the systemvoltage requirement
do not match, as a hazardous condition and severedamage could
result.272.3 LocationThe ELMO-Pack TM must be installed on a
horizontal, level surface. Floor anchors are notrequired because of
low vibration levels. If anchors are used, care must be taken
toeliminate pipe stress load on the inlet piping.A flex connector
should be installed.At least 2 feet of air space should be allowed
between any wall or obstruction and theheat exchanger air
intake.This will assure adequate flow of cooling air and
providemaintenance access.For expandable systems, place the vacuum
receiver skid on the far left of the installationpad.Then place
each expansion module next to the receiver skid and connect the
pipingas indicated in Figure 2-1.For expandable systems, run the
provided wiring from the panel to the vacuum expansionmodules.2.4
Wiring InstallationWire all components in accordance with the
wiring diagram in Section 1.0, ControlPanel, or the wiring diagram
supplied with your equipment.See Figure 1-2 (Non-expandable system)
or Figure 2-2 (expandable systems) for details.If the system is
supplied with a Siemens Panel, wire the power to the panel.28Figure

Inspection1.Check the seal-oil liquid level and prime the pump with
oil as described inSection 2.5.2.Open all valves in the operating
liquid line to allow service liquid flow.3.Make sure all drain
valves are closed.4.Open block valves on all gauges.5.Check all
piping making sure the connections are in accordance with Figure
2-2.6.Open any isolation valves in the suction and discharge
piping.7.Check that the power supply to the motor has correct
voltage and amperage asspecified in supplied wiring
diagram.8.Isolate the power source from the motor to prevent
accidental starting of the motorand system.9.Install all necessary
disconnects in accordance with local codes.10.For each installed
pump briefly jog the motor by placing the panel selector in
themanual position for a few seconds.Observe the direction of
rotation of the pump.Correct direction of rotation of the vacuum
pump for BV2 and AV2 systems isclockwise when viewed from the
non-drive end of the motor; for BE1 systems thecorrect direction of
rotation of the vacuum pump is clockwise when viewed from thedrive
end of the pump.Change pump or panel wiring(switch location of 2
leads) ifpump is operating in opposite direction from that
indicated.WARNINGLocal codes may require and Siemens recommends
installation of fuseddisconnects or circuit breakers within sight
of the control panel.Standard control panels are not supplied with
disconnects.Check local code requirements prior to
installation.CAUTIONOnly a qualified electrician should
attemptelectrical installation of this system.323.2 StartupWith
steps 1 through 9 complete from section 3.1 (Preliminary
Inspection), switch allpumps to auto mode.All vacuum pumps should
start.Observe the vacuum gauge on theinlet connection. The gauge
should start to indicate vacuum within 15 seconds. If novacuum is
indicated, turn off the system immediately. Perform all steps 1
through 9 fromsection 3.1 (Preliminary Inspection).There will not
be a vacuum if there is no systemresistance to gas flow at the
suction.CAUTIONRepeated starts can cause overheating of the motor,
which may result inmotor burnout (particularly for across the line
starting).If repeated starts are made, allow sufficient time
between trails topermit heat to dissipate from windings and rotor
to preventoverheating.Please consult the motor manual.1. Confirm
the oil in the separator is at the correct level and trace the
operating liquidline confirming all valves are open and the seal
liquid is flowing from the separator tothe pump.2. Confirm that
there are no closed valves in the discharge piping from to the
pump.(NFPA systems only)Run the system for hour and check for the
following:1. Stable vacuum.2. No unusual vibration or noise.3.
Operating temperature should be 150-190 F.4. Acceptable operating
pressure at the separator should be 1-3 psig.5. Acceptable
operating pressure for the operating oil at the pump should be 1-8
HgVacuum.6.Seal oil level in separator level gauge.3.3 Shut downThe
ELMO-Pack TM system design makes shut down and re-start virtually
one stepoperations. When the system is to be shut down simply turn
the power supply to thesystem off. The ELMO-Pack Oil TM seal system
is supplied with an inlet check valve toprevent any fluid being
pulled from the pump back up into the system piping.333.4 Vacuum
switch adjustment (expandible systems only)Each vacuum pump in an
expandible system is provided with a pressure switch (SeeFigure
3-1) to control the vacuum cut-in point of the pump.The factory
settings areoutlined in Table 1-2, Section 1.3.2.1.Each switch is
field adjustable to alternate settingsby following the procedure
outlined in this section.Figure 3-1Typical Pressure Switch3.4.1
OperationThe controls are actuated by vacuum.The following sequence
occurs: 1) an increase invacuum (towards 30 in. Hg vacuum), causes
circuit A-B to close and B-C to open (SeeFigure 3-2).This is the
Trip setting.2) when the pressure returns to a predeterminedlower
vacuum (towards atmospheric pressure), circuit A-B will open and
circuit B-C willclose.This is the Reset point.The difference
between the Trip and Reset settingis the differential. Figure
3-2Standard Contact Arrangement for Negative Pressure343.4.2
AdjustmentGenerally, unless otherwise specified, controls shipped
from the factory are set at theoperating range vacuum indicated in
Table 1-2 and minimum differential.3.4.3 Operating range
adjustmentTurn range adjustment Screw A counterclockwise to lower
the upper and lowervacuum settings.To increase the upper and lower
settings, turn Screw A clockwise.The approximate upper vacuum
setting is shown by indicators on the outer edges of
thenameplate.3.4.4 Differential adjustmentWhen the differential
blade is at the low point of the differential cam the control
willfunction at minimum differential.To increase the differential,
turn adjustment Screw Bcounterclockwise.This will decrease the
higher vacuum setting only.To decrease thedifferential, turn
differential adjustment Screw B clockwise.This will lower the
highersetting only.Condensed instructions are supplied with open
style controls and are on the inside of thecover on enclosed
devices.NOTE: Use the vacuum gauge (See Figure 1-1) when setting
the control.CAUTIONThe range adjustment Screw A should not be
adjusted beyond thepressure indicated on the pressure scale as this
may cause the control tomalfunction.It is recommended that a
periodic inspection of gauge vacuum be made and the vacuumcontrol
adjusted to compensate for application variables.35Section 4.0

section.4.2 Recommended Schedule of MaintenanceThe following
schedule is a recommended guide based upon system operation
undernormal conditions.The frequency of the maintenance intervals
should be adjusted asrequired by the actual operating
conditions.WEEKLY:Check all gauges to verify that they are reading
within the specified ranges (seesection 1.2).Observe oil flow in
the scavenging line.Check the system for any abnormal noise or
vibration.Check for oil leaks.Check oil level.MONTHLY:Clean or
replace inlet filter element (if applicable).Clean y-strainer
screen.Visually inspect and clean entire system as required.Check
for water in the separator, drain if necessary.EVERY THREE MONTHS
OR 1000 HOURS OF OPERATION:Check coupling or pulleys for tightness
on shaft.Check v-belt tension (if applicable).Check amperes draw
for each motor.EVERY 18 MONTHS OR 10,000 HOURS OF OPERATION:Change
seal oil using Siemens ELMO-Oil.Replace the coalescing filter in
separator if backpressure is 3 psig.Replace coupling element or
v-belts as required.Inspect and clean the scavenge line.EVERY
20,000 HOURS OF OPERATION:Replace the vacuum pump mechanical
seals.Replace the vacuum pump bearings.36WARNINGShut down the
system and lock out powerbefore proceeding with any of the
scheduled maintenance.4.3 StrainerWith the pump shut down, close
the ball valves located directly upstream and directlydownstream
from the strainer.Place a catch pan directly below the strainer to
catchescaping oil from the strainer and pipe (see Figure 4-1).With
proper sized wrench,loosen the screen cover nut and remove (see Fig
4-2). Note that the stainless steel screenshould slide out easily.
Remove the screen from the housing, clear any dirt or debris,
andinspect screen for tears, old oil buildup or damage. After
clearing the screen replace itand be sure that the screenslides
easily back into place. Do not force the screw anchorsinto place;
if resistance is felt, check the housing cavity for
obstructions.Use Teflon tapeto reseal the threads of the
strainer.Once the seal is re-established, be sure to open
bothisolation valves to ensure proper operation of the
system.Figure 4-1 Preparing to clean Y-strainer. Figure 4.2.
Cleaning the Y-strainerscreen.4.4 Operating Liquid Seal OilThe
ELMO-Pack TM Oil Seal System is shipped with factory recommended
seal fluid. Werecommend the use of Siemens ELMO-22005G (See
Appendix for MSDS Sheet) sealfluid to achieve optimum performance
of the system.Contact the factory to reorder therequired
replacement.37DANGEROperation on improperly selected oil can cause
overheating,overloading of the motor or degradation of the
elastomers used in thepump. Use only Siemens ELMO-22005G vacuum oil
to preserve warrantycoverage.4.4.1 Draining OilPlace a catch pan
under the ball valve located at the separator tank bottom (See
Figure 4-3) With the pump shut down, open the ball valve and drain
the operating liquid oil,emptying the catch pan to drain any water
or dirt that may have accumulated in theseparator below the
operating liquid outlet connection (See Table 2.1 for quantity of
oilin system). When the oil has completely drained from the
separator, shut the valve.Locate the system drain plug upstream
from the thermostatic bypass valve in the verticalpiping tee (see
Figure 4-4).Place a catch basin under the plug.Remove it and allow
theoil to drain. After all the oil is completely drained reinstall
the drain plug using Teflontape to assure a proper seal. Inspect
used oil. If it seems dirty, flush the separator withclean oil as
needed until the flushing oil runs clean.Properly dispose of the
old oil.Figure 4-3.Draining the oil Figure 4-4.Using the total
drainseparator. to remove all oil from the system.If removing the
pump from the system, be sure to drain all of the oil from the
casing.Todo this, locate the total drain on the bottom of the pump
cover.Remove the drain plugand allow the oil to flow into a catch
basin.Replace the total drain plug, along with thereusable gasket
when finished.384.4.2 Adding oilWith the separator flushed, close
the ball valve located at the tank bottom.Place oilabsorbent mats
under the oil fill connection.Remove the square head pipe plug from
theoil fill connection on the separator. Place the funnel in the
fill connection opening andpour new oil into the separator.(See
fig. 4-5) While adding oil check the level gaugelocated below the
fill connection for oil level. Oil level must be maintained at the
serviceliquid connection of the pump (models from 2 to 25
horsepower) or pump shaft centerline (models from 30 horsepower and
higher) . Over filling will cause the pump tooverwork and become
hot. After reaching the required level, (See Section 2.5, Table
2.1)operate the pump for 3 to 4 minutes.Now stop the pump and the
check the oil levelagain. If required, add additional fluid up to
the recommended level.Figure 4-5.Filling the separatorwith
oil.CAUTIONDo not add oil through the gas discharge opening,
sinceit will collect in the oil mist coalescing element and cause
start-upproblems.Only add oil through the oil fill connection.4.5
Inlet Filter (optional)Check after 50 hours of pump operation,
clean or replace the element every 1000 to 3000operating hours
depending on the application or when excessive loss of vacuum
isnoticed during operation. Be careful during inspection and
cleaning not to knock offexcessive dirt or debris into the pump
inlet. Remove any foreign debris from the filterhousing.FIRST TIME
START-UPWhen starting a system for the firsttime after a rebuild of
the pump or onreceipt from the factory, it may benecessary to prime
the pump. See Section 2.5 for detailedinstructions.394.6 Discharge
Oil Filter4.6.1 Removing FilterDisconnect and remove any discharge
piping. Disconnect the scavenge line tubing at theconnection
located below the in-line sight glass (Figure 4-6).Loosen &
remove the hexbolts, hex nuts, and washers. Store the loose
fasteners in a secure place. Place oilabsorbent mats around
separator base to collect any excess oil in the discharge oil
filterupon removal from the separator. Remove the separator top
plate vertically being carefulnot to damage the internal scavenge
line piping (Figure 4-7) Remove the internalscavenge line from the
separator top plate to avoid damaging the piping while the filter
isbeing replaced.Lift the filter vertically to avoid lodging the
filter within the separatortank. Properly dispose of the old
filter.Figure 4-6. Removal of separator lid.Figure 4-7. Removal of
oilfilter.4.6.2 Replacing FilterWith the old filter removed per
instructions above, place the new discharge oil filterinside the
separator.If necessary, reconnect the internal scavenge line tubing
to theseparator top plate.Orient the separator top plate so the
external scavenge line realignswith the vertical scavenge line
tubing from the pump and reinstall the top plate on theseparator.
Replace hex bolts, hex nuts, and washers in the separator top plate
and tighten.Reconnect the vertical scavenge line tubing from
pump.404.7 CoolerThe air cooler should maintain a 150-190F pump
discharge temperature. If thistemperature is not maintained, check
the following:1.Fan motor not functioning (contact Siemens customer
service for replacement.)2.Fan motor amps too high (check
voltage).3. Visually inspect fan and radiator for any visible
damage or wear.4. Clean Radiator fins as required if damaged, bent
or clogged with debris.5. Oil flow blocked.Check y-strainer and
clean as required.4.8 Inlet Check ValveIf an inlet check valve is
replaced or reinstalled be sure that the valve is installed so
theflaps fall downward. This check valve is provided without spring
to assist close. Gravityholds the valve open when it is installed
in the vertical position with flow downward.This valve should only
close when the vacuum pump is de-energized and the process isstill
under vacuum. The valve then closes and stops any flow of oil into
the inlet pipingand the process equipment.4.9 Thermostatic Control
ValveThe Thermostatic control valve is a non-adjustable valve. The
valve comes factory set tooperate at 150F.When the discharge
temperature gauge reads less than 150F, the linefrom the thermal
bypass valve to the heat exchanger should be cool to the
touch.Above150F, this line should feel hot.If this is not the case,
contact a Siemens customerservice representative for a
replacement.CAUTIONExercise care when touching piping with hot oil
flowing inside.Do not touch if the discharge temperature gauge
reads above 160 F, asburns may result.4.10 Pump Disassembly4.10.1
ApplicabilityThese instructions apply only to the 7.5 Horsepower
through 25 horsepower model AV2ELMO-Pack TMsystems.For the systems
below 7.5 horsepower consult the appropriateSiemens Manual for 2BV
style pumps.For systems greater than 25 HP, consult theSiemens
Manual for 2BE1 style pumps.Copies of these manuals are supplied
whenapplicable or may be obtained directly from our website,
www.siemensvpc.com.414.10.2 Removal of Pump from ELMO-Pack
SystemsShut off and lock out the main power disconnects.Completely
drain the oil from theELMO-Pack TM oil sealed system as described
in Section 4.4.Disconnect and remove theoperating liquid piping,
inlet piping and discharge piping from the pump/motor
assembly.Using the illustrated lifting method (Figure 4-8), support
the pump with an overheadcrane and remove the bolts holding the
pump/motor assembly to the system frame.Pullout the pump/motor
assembly and relocate it to a suitable work area.Figure 4-8. Proper
lifting of the pump and motor assembly.4.10.3 Stabilizing the
Assembly Prior to DisassemblyIt is recommended that the pump/motor
assembly be held to the work surface with a C-clamp to avoid damage
to the pump during disassembly or re-assembly.CAUTIONBe sure that
the work surface chosen for the disassemblyand re-assembly can
support the weight of the unit.424.10.4 Cover DisassemblyWith the
pump secured to the working surface, locate the 5 hex bolts in the
pump cover(Figure 4-9).Remove the bolts and pull the cover off of
the pump.The cover alsocontains the port plate, which should only
be removed from the cover if necessary (seeTrouble Shooting Guide,
Section 6.0).Figure 4.9.Removal of pump cover. Figure 4.10.Removal
of port plate from the cover.4.10.5 Removal of Port Plate from
CoverWhen required, the port plate can be removed from the
cover.Place the cover/port plateassembly on wooden blocks so that
the port plate is laying flat parallel to the worksurface.Remove
the total drain connection plug located at the bottom of the
cover(Figure 4-10).Place a 3/8 diameter bolt (minimum 6 in length)
through the total drainconnection and tap it with a hammer until
the port plate comes loose from the cover.CAUTIONDo not apply
excessive force when removing the port platefrom the casing as
damage to the port plate could result.434.10.5.1 Removal of Seal
Compound from Port Plate/Cover Surfaces.The port plate is sealed to
the cover by application of a liquid sealant to the commonsurfaces
on the reverse side of the port plate and the cover.Before
re-assembly, oldliquid sealant (blue in color) should be removed
from these surfaces with a putty knife orsuitable wire brush.During
re-assembly, a liquid sealant must be reapplied to these
samesurfaces any time that the port plate is removed from the
casing.4.10.5.2 Variable Discharge Valve RemovalThere is a
stainless steel plate bolted to the outboard side ofthe port plate
at the discharge port (Figure 4-11).Removethis plate and the Teflon
flapper valve found beneath it.Inspect the flapper valve for damage
and replace asnecessary.4.10.6 Impeller RemovalUsing a slotted
crossarm puller (Snap-On Model Number CJ84-4 or equal) and
apneumatic wrench (Figure 4-12), pull the impeller off of the shaft
(Figure 4-13).It ispermissible to heat the hub of the impeller when
necessary.There is a fluted tolerance ring between the shaft and
impeller that assists in holding theimpeller to the shaft.This ring
should be replaced (do not re-use) during re-assembly ofthe
pump.Now remove the key in the shaft and observe the mechanical
seal.CAUTIONThe flapper valve must be installedfor proper operation
of the pump.Operation without a flapper valve ora damaged flapper
valvewill affect pump and systemperformance.Figure 4-11. Inside
view ofport plate and cover.44CAUTIONReuse of the tolerance ring
duringre-assembly may cause theimpeller to seat improperly ormove
on the shaft, which coulddamage the pump.4.10.7 Mechanical Seal
RemovalPlace some clean oil on the shaft to aid in removal of the
mechanical seal.Slide themechanical seal out and off of the
shaft.Place it in a clean area and protect the surfacesof the seal
faces from damage.Figure 4-13.Removal of impellerwith slotted
crossarm puller.454.10.8 Coupling RemovalAccess the coupling
through the port in the side of the skirt.Loosen the setscrews
andremove the coupling through the access port.4.10.9 Motor
RemovalSupport the motor by using an overhead crane(Figure
4-14).Locate the four bolts holding themotor to the adapter
plate.Remove the bolts andremove the motor from the work
area.Figure 4-14.Removal of motor from pump pedestal.CAUTIONDo not
operate the pump using motorsrunning at speeds other than those
recommended by Siemens.Performance and system reliability will be
affected.4.10.10 Shaft RemovalThe pedestal houses the shaft and two
deep grooveball bearings.From the pump side of the pedestal,remove
the v-ring and bearing cover.There aretwo shims under the bearing
cover.Remove theseand store in a clean area (Figure 4-15).On
themotor side of the shaft, remove the bearing coverand the
compression washers.With both bearingsexposed, gently remove the
shaft from thepedestal.Both bearings will be secured to
theshaft.Figure 4-15.Bearing pedestalcomponents.464.10.11 Bearing
RemovalUsing the bearing puller and a pneumatic wrench, remove both
bearings from the shaft(Figure 4-16).4.10.12 Re-assemblyRe-assembly
is the opposite of disassembly, with the following additional
instructions.4.10.12.1 ClearancesWhen re-assembling the impeller to
the shaft, use a feeler gauge to measure the clearancebetween the
front face of the impeller and a metal straight edge placed against
the face ofthe casing.Refer to Table 4-1 for required
clearances.Table 4-1 Recommended clearances for 2AV2
pumps.HORSEPOWER MODEL CLEARANCE7.5 2AV211010 2AV211115 2AV212120
2AV213125 2AV2161.15 to .20 mm(.006 to .008 inches)Use the crossarm
puller to re-assemble the impeller to the shaft.4.10.12.2 Seal of
Port Plate to CasingApply liquid sealant to all common faces
between the back of the port plate and the coverprior to
re-assembly.Do not over apply sealant to assure proper operation of
the pump.The recommended sealant is Dow Corning 832 or
comparable.Figure 4-16.Bearing Removal from pump shaft.474.10.12.3
O-Ring ReplacementIt is often difficult to replace the o-ring
located on the outside of the inner face of the portplate to seal
it to the casing.To assist in placing the o-ring properly, it is
permissible tospray the o-ring with adhesive (3M High Strength
Binding Spray Adhesive or equal) toassist in re-assembly.4.11 Motor
MaintenanceAt a minimum, the bearing lubrication, insulation
resistance and cleanliness of the motormust be periodically checked
as part of a routine maintenance program.4.11.1 Bearing
LubricationCAUTIONDo not lubricate motor while in operation, since
excess grease will beforced through the bearings and into the motor
before it will force itsway out of the drain plug.Excess grease
accumulation on windingsreduces insulation life.Bearing life is
assured by maintaining proper alignment, proper belt tension, and
goodlubrication at all times.Prior to shipment, motor bearings are
lubricated with the proper amount and grade ofgrease to provide six
months of satisfactory service under normal operation
andconditions.For best results, grease should be compounded from a
polyurea base and a good grade ofpetroleum oil.It should be of No.
2 consistency and stabilized against oxidation.Operating
temperature range should be from 15F to +300F for class F and
Hinsulation.Most leading oil companies have special bearing greases
that are satisfactory,such as Exxon Unirex N3.Re-lubricate bearings
every six months (more often if conditions require), as
follows:1.Stop the motor.Lock out the switch.2.Thoroughly clean off
pipe plugs and remove from housings.3.Remove hardened grease from
drains with stiff wire or rod.4.Add new grease to inlet with hand
gun until small amount of new grease isforced out of drain.5.Remove
excess grease from ports, replace inlet plugs, and run motor
hourbefore replacing drain plug.6.Put motor back into
operation.484.11.2 Checking Insulation ResistanceCheck insulation
resistance periodically.Any approved method of measuring
insulationresistance may be used, provided the voltage across the
insulation is at a sage value forthe type and condition of the
insulation.A hand cranked megger of not over 500 volts isthe most
convenient and safest method.Standards of the Institute of
Electrical andElectronics Engineers, Inc. (IEEE) recommend that the
insulation resistance of statorwindings at 75C, measured at 500
volts DC, after one minute should not be less than:Rated Voltage of
Machine + 1000= Insulation Resistance in Megaohms 1000This formula
is satisfactory for most checks.For more information, see IEEE
StandardNo. 43, Recommended Practice for Insulation Resistance
Testing of AC RotatingMachinery.4.11.3 Checking Motor
CleanlinessCAUTIONDo not attempt to clean motor while it is
operating.Contact withrotating parts can cause severe personal
injury or property damage.Stop the motor and lock out switch before
cleaning.The motor exterior must be kept free of oil, dust, dirt,
water, and chemicals.For fancooled motors, it is particularly
important to keep the air intake openings free of
foreignmaterial.Do not block air outlet or inlet.On
non-explosion-proof TEFC motors, a removable plug in the bottom
center of themotor frame or housing permits removal of accumulated
moisture.Drain regularly.494.12 V-Belt Drive InstructionsELMO-Pack
systems utilizing a V-belt drive must be properly set up and
positionedbefore stating.Sheaves must be aligned with the grooves
parallel to each other.Setscrews and mounting bolts should be
checked to ensure tightness on the motor andpump shafts.Ensure that
sheaves are properly installed and aligned before tensioning
thedrive.Belts should be placed over the sheaves and into the
grooves without being forcedinto place.1.With all belts in their
grooves, adjust the center distance and take up the slack untilthe
belts are fairly taut (use the adjusting bolt on the motor slide
base to perform thisoperation) with a slight bow on the slack
side.2.Test the drive under load conditions.If the bow on the slack
side is too tight or tooloose, shut down the unit and adjust the
center distance accordingly.Retest the drive.Belts which slip or
squeal on start are usually too slack, which results in
inefficientoperation, high belt temperature and shortened belt
service life.Belts which are tootight cause high motor amperage or
excessive bearing load which may result inshortened bearing and
shaft seal life.3.The belts should be monitored frequently for the
first few days of operation.Thebelts will seat themselves in the
grooves during this period.They may also stretch abit requiring
some re-adjustment.NOTE:Belts should always be replaced as a
set!Figure 4-17.Check individual unit rotation arrows to determine
proper direction ofrotation.50Section 5.0 STORAGE5.1SHORT TERM (3
MONTHS OR LESS)The following steps must be followed:1. ELMO-Pack TM
Oil Seal System must be stored in a warehouse free from
extremetemperatures, humidity and corrosive atmospheres2. If
unusual vibration exists at the storage facility isolator pads
should be placed underthe ELMO-Pack TM Oil Seal System .3.All
breathers and drains are to be sealed while in the storage facility
to protect from moisture accumulation.4.Minimize condensation
around the ELMO-Pack TM .Place desiccant around the motor and other
controls to reduce the effect ofmoisture5.2LONG TERM (OVER 3
MONTHS)1. ELMO-PACK TM Oil Seal Systems are to be kept in a
warehouse free from extremetemperature, humidity and corrosive
atmospheres.2. If unusual vibration exists at the storage facility
isolator pads should be placed underthe ELMO-Pack TM Oil Seal
System.3. All breathers and drains are to be sealed while in the
storage facility to protect frommoisture accumulation.4. Minimize
condensation around the ELMO-Pack TM Oil Seal System. Place
thedesiccant around the motor and other controls to reduce the
effect of moisture.5. Coat all exposed machined surfaces with a
material to prevent corrosion. (EXXONRust Ban #392, or equal)6.
Before placing into storage, measure and record the electrical
resistance of thewinding insulation with a megger or an insulation
resistance meter. Minimumacceptable Megohm level is the insulation
kV rating + 1 Megohm. This informationwill be needed when removing
the system from long-term storage.7. When removing the ELMO-Pack TM
Oil Seal System from long-term storage themotor windings are to be
meggered and this reading is to be compared to with thereadings
taken before the package was put into storage. The insulation
resistancereading must not have dropped more than 50% from the
original readings from line#6.Any drop below this point
necessitates electrical or mechanical drying.51Section 6.0 Trouble
