1.7 Unauthorized Modifications andManufacture of Spares
Modifications or changes to machines / equip-ment are only
permissible with the manu-facturer's agreement. Original spare
partsand accessories authorized by the manufac-turer ensure
safety.The use of other components revokes any lia-bility for
consequences which may result.
1.8 Improper Application
Delivered machinery / equipment is only gua-ranteed safe for the
use specified.
This machine / equipment was designed inaccordance with the
prescribed conditions ofuse.The limits of use are laid down in the
con-ditions of use and should in no way be ex-ceeded.
1.9 Specific Points for the Use of aSpectra Pump
A Spectra pump must be used for the pur-pose only for which it
was sold.
If you change or wish to change the processmedium, you must
check with either thesupplier or manufacturer that the pump
issuitable for the new medium. This is espe-cially important with
aggressive, poisonous orotherwise hazardous substances.
Pump criteria include:
1. Compatibility with the medium
2. Suitability for seal design / material,especially the shaft
seal
3. Resistance to pressure and temperatureof the medium.
Please note that Spectra pumps are progres-sing cavity pumps and
as such can generatevery high pressure.
A blockage or the chance closure of a valvein the discharge line
can cause a pressure risemanifold as high as can be tolerated by
theinstallation. This can result in the bursting ofpipes, which
must be avoided especially inthe case of dangerous media.
Corresponding safety equipment musttherefore be installed, for
example anemergency stop button, a pressure reliefvalve with return
pipe or a bursting disc.
During maintenance and repair work on thepump please note the
following:
1. Ensure that the pump drive can notbe turned on without
authorization.
2. When opening the pump followthe instructions for handling
themedium (eg. protective clothing,no smoking etc).
3. Before putting the pump back intooperation ensure that all
guards andother safety devices (eg. drive–beltprotection, coupling
protection) areproperly re–installed.

2 Description
The Spectra pump is a progressing cavitypump.The main components
which determine thesystem discovered by Professor René Moineauare a
rotating part, called the rotor and a sta-tic part, called the
stator.The rotor is a helical screw with an extreme-ly large pitch,
large thread depth and smallcentre diameter with round
cross-section for1/2-geometry and elliptical cross-section
for2/3-geometry. The stator has a two start orresp. 3 start thread
and is double or resp. 1.5the pitch length of the rotor. This
providesspace for the medium between the rotor andstator. When the
rotor turns round inside thestator the medium moves continuously
fromthe inlet to the outlet.
The universal Spectra pump system unifiesmany positive
characteristics of other pumptypes:
� Like centrifugal pumps Spectra pumps haveno suction or
pressure valves, but do have astable flow rate in proportion to the
numberof revolutions.
� Like piston pumps Spectra pumps have asuction capability of up
to 8.5 m vacuummetric.
� Like membrane and peristaltic pumps theSpectra pump can
transport every type ofinhomogenous, gaseous and abrasive media,as
well as those that are not of a liquid con-sistency or contain
solids and/or fibrous mate-rial.
� Like gear pumps and screw pumps theSpectra pump is capable of
coping with highmedium viscosities.
� Like piston, membrane, gear or screwpumps the Spectra pump can
perform dosingoperations.

2.2 General Data
Noise emissions:
The maximum permitted noise emission level at a work place is 70
dB (A).
The noise level was measured in accordance with DIN Standard
45635-24-01-KL2 to assure that the pump does not exceed 70 dB
(A).
Noises generated by the drive and pipes are not included in the
aboveemission value.
A prerequisite for the noise emission level of ≤ 70 dB (A) is
that the pump is operated in a cavity free regime and is bolted to
a concrete base.

3 Packaging, Transportation, Storage
3.1 Packaging and Transportation
The packings are labelled and symbols give the handling
instructionsin accordance with DIN 55402.On receipt check for any
transport damages. Transport damages should be reported to the
transporter immediately.The pumps should be transported as closely
as possible to the location of installation and only there should
they be uncrated.
Uncrated horizontal pumps should be lifted by using a shackle
which can be attached to the baseplate. The bolt holes of the frame
or the lifting lugs attached to the baseplate could be used as
shown on the installation drawing.
Vertical pumps should be lifted by using the bolt down
holes,lifting lugs or shackles attached to the baseplate. This is
shown onthe installation drawing. For most applications, the drive
is mountedon top of the pump.
Be careful when lifting top heavy pumps. The centre of gravity
may beabove the points where the lifting gear is attached to. If
the case, secure additionally against tipping over!
Vertical pumps should not be deposited unless they are secured
vertically.Hazards of tipping! Deposit only in horizontal
position!
It is essential to avoid that the total pump unit be suspended
witheye bolts of the motor or gear box. These eye bolts should be
used for lifting the motor and/or the gear box only.
The Accident Prevention Rules, Section 18.4 relating to lifting
accessories for the lifting of loads (VBG 9a) must be strictly
adhered to.
Because of the variety of possible pump designs and
applications, only general instructions can be given here. These
should be good enough for experienced assemblymen or transportation
experts.When in doubt, please ask for detailed information on the
pump unit concerned.

When moving the pump or unit on wheels strictly attend to the
following:
� Pad lock the motor drive and secure against unintended
starting up.
� Move the pump unit carefully and slowly, especially where the
ground is uneven. Hazards of tipping!
� Ensure a stable position of the pump or unit at the operating
/storage place and secure it by actuating all clamping devices on
all the wheels or rollersagainst voluntary moving away.
� Where fitted loosely, carefully watch the pipe bends when
pumping.Power of repulsion!
� Where necessary, secure the pump unit additionally with
support blocks.
3.2 Storage
The pumps are preserved for transport unless specified
otherwise.In cases of longer storage the pumps should be handled as
follows until installation:
� Stator:
If the pump is not to be used immediately, then the elastomer
along the contact line between rotor and stator may become
permanently distorted (compression-set). This will increase the
break away torque. Therefore, the stator should be removed and kept
separately in a clean, cool and dry environment. Standard DIN 7716
summarizes detailed information on the storage of rubber products,
some of which is gathered here, and the following notice applies to
a storage for a period of up to six months.
General
Most of the rubber products may change their physical properties
under unfavourable conditions or if treated improperly, which will
result in a shorter lifetime. Or they may become useless through
excessive hardening, aging, regenerating or permanent deformation,
also because of blistering, cracking or other damages appearing on
the surfaces. The changes may occur under the influence of oxygen,
ozone, heat, light, humidity, solvents or because of storing the
products under tension. If stored and treated properly, the rubber
products will keep their properties, even over a long period of
time (some years), almost unchanged. This does, however, not apply
to uncured rubber compounds.

3 PACKAGING, TRANSPORTATION, STORAGE PAGE3.1
Store room
The environment in which rubber products are being kept must be
cool, dry, free of dust and rather airy, and they must not be
stored in the open, not even in a weather sheltered space. Rubber
products should be kept in surroundings not having less than minus
10 °C and not more than plus 15 °C. Store rooms should not be damp,
and it must be ensured that there will be no condensation. Most
favourable is an environment offering a relative humidity under 65
%. Rubber products must be protected against light, particularly
direct sunlight or artificial light when having a high UV portion.
They should furthermore be kept away from ventilation, especially
draught, by wrapping them up. As ozone is very aggressive and
harmful there should be no store room used which houses equipment
likely to produce ozone, e.g. electric motors or other equipment
which might bring about sparks or other electrical discharges.
There must be no solvents, oil, grease, lubricants or any chemicals
kept in a store room.
� Rotor
Please support with wooden blocks and cover up against harm from
mechanical impact.
� Pump parts in stainless steel
No grease coating necessary.
� Other, non-coated pump parts
Protect with grease.

5 Start-up
The Spectra pump design requires strict attention to the
following:
Never run the Spectra pump dry!A few rotations in dry
conditionwill damage the stator!
� Before starting up for the first time, fill the pump with
medium.In the case of high viscosity media fill with a liquid.Pump
priming is vital to ensure lubrication of the rubber stator.Fill
the piping on the pump suction side.In anti–clockwise rotation
only: Fill the pump housing.
The Spectra pump is a progressing cavity pump which can produce
pressures that may cause the bursting of vessels or pipes.
The power transmission train (shaft, coupling rod, joints,
rotor)of the pump may be overloaded thus resulting in damage or
breakage.
Also the pump housing parts with their connections may be
overloaded and break. There is a table in Section 4 of these
Maintenance and Operating Instructions showing the pressure
resistance of the pump housing parts.
Never run the pump against a closed inlet or outlet valve!
� Open valves and vents before starting the pump!
� Check the direction of rotation by briefly switching on the
pump motor.

6 Temporary Shutdown
� After stopping the pump empty and if necessary rinse it if
– the medium might freeze due to the temperature surrounding the
pump. Especially where there is a danger of frost if the pump is
installed outside a building
– the medium tends to solidify or harden
– the medium tends to glue up the shaft seal.
� Stator:
When stored for a long period, the elastomer along the contact
line between the rotor and stator may become permanently distorted
(compression-set).This will increase the break away torque. For
this reason, the stator should be removed (please observe Section
9!), and stored in a cool, dry place in air tight package to give
protection against light and air.
� Rotor:
Support the rotor on wooden blocks and cover to protect it from
mechanical damage, after the stator has been removed.
� Stand-by pump:
A stand-by pump is sometimes used as a back-up for the main pump
and, when standing idle for longer periods, should be operated from
time to time. The pump may otherwise become seized when being
started up. This is due to compression set i.e. distortion of the
stator against the surface of the rotor.

7 Maintenance
7.1 Pumps in General
� The pumps should be regularly rinsed or cleaned if deposits of
medium are likely to build up (sedimentation).
If the pump needs to be opened to do this, ensure that the
pumpand motor are switched off and cannot be turned on
accidently(eg. by removing the fuse).
Periodical standstill to allow for cleaning during operation
depends on themedium and type of operation.
� The pump can be cleaned:
– through the cleaning ports provided in the pump housing
– manually by dismantling the pump.

7.2 Lubrication
The Spectra pump does not require frequent lubrication.
� Maintenance of the drive should be carried out accordingto the
drive manufacturers instructions.
� Maintenance– where no manufacturers instructions are available
and– when normal conditions of use exist:
– Strip down the drive unit– Remove the bearings– Clean all
parts– Renew the lubricant
every 5000 operating hours or at least every two years.
Special lubricants are often specified for mechanically
controlled variable speed drives.It is therefore important to
follow the drive manufacturersmaintenance instructions.

7.5 Shaft Sealing through Single Mechanical Seal
There are various constructions of mechanical seals. Especially
advantageous is the use of standard mechanical seals according to
DIN 24960. These seals have regardless of their brand the same
fitting dimensions which makes them interchangeable.Mechanical
seals with a coil spring can only be used for pumps which are run
in one direction of rotation.
� The seal specification of a Spectra pump is recordedon the
order confirmation sheet.
� Pumps fitted with direction dependent seals should never be
run in the opposite direction ofthe rotation arrow.
� If excessive leakages occur the spring tension and the seal
surfaces should be checked, and the seal be replaced, if
necessary.
Single mechanical seals usually work without any
additionalequipment.

/ cause and some hints how to handle the problem .Thus the actual
cause of the problem can be narrowed down andeventually
detected.
– If you find further cross-marked boxes on one of the linesand
should there appear corresponding problems as well,then the likely
cause of the problem has been detected.
� The table helps in finding the root of the problem and will
give you the remedy if it is straight forward. For more complicated
problems the manufacturer has to be consulted.

10.4 Replacing the Wear Sleeves of Adapter, Rotor and Coupling
Rod
The wear sleeves (5435, 5440) have a very tight fit.A press
should be used to remove or refit them.
It may be possible though to drive the damagedsleeves out with a
suitable mandrel. A rigid vicehowever is needed at the least for
pressing newsleeves (5435, 5440) in again.
Orient the wear sleeves (5435) so that their ovalbore agrees
with the longitudinal axis of thecoupling rod (1998).
Generously oil the wear sleeves (5435, 5440).
Every wear sleeve (5435, 5440) has got one smallerouter diameter
on one end for better insertion intothe bores of the coupling
rod.
Ensure the sleeves are placed in the correct orien-tation to the
coupling rod (1998).

Operating Manual is essential. Getriebebau NORD accepts no
liability for damage to persons, materials or assets as a result of
the non-observance of this Operating Manual, operating errors or
incorrect use. General wearing parts, e.g. radial seals are
excluded from the warranty. If additional components are attached
to or installed in the gear unit (e.g. motor, cooling system,
pressure sensor etc.) or components (e.g. cooling system) are
supplied with the order, the operating instructions for these
components must be observed. If geared motors are used, compliance
with the Motor Operating Manual is also necessary. If you do not
understand the contents of this Operating Manual or additional
operating instructions, please consult Getriebebau NORD!
1.2 Safety and information symbols Please always observe the
following safety and information symbols!
Danger!
Risk of fatalities and injury
Attention!

Danger!
Installation and maintenance work must only be performed when
gear units are at a standstill and have cooled down. The drive must
be isolated and secured to prevent accidental start-up.
Tighten the drive elements or secure the parallel key before
switching on.
Danger!
Only transport use the eyebolts attached to the gear unit. No
additional loads may be attached. Transportation aids and lifting
gear must have an adequate load-bearing capacity.
If geared motors have an additional eyebolt attached to the
motor, this must also be used. Avoid pulling the eyebolts at an
angle. The thread of the eyebolt must be fully screwed in.
Observe all safety information, including that provided in the
individual sections of this Operating Manual. All national and
other regulations on safety and accident prevention must also be
observed.

Please observe all of the general safety information in Section
1.4, 1.3 and in the individual sections.
3.1 Storing the gear unit For short-term storage before
commissioning, please observe the following:
• Store in the fitting position (see Section 6.1) and secure
gear units against falling • Lightly grease bare metal housing
surfaces and shafts • Store in dry rooms • Temperature must not
fluctuate beyond the range of –5 oC to +40 oC • Relative humidity
less than 60% • No direct exposure to sunlight or UV light • No
aggressive, corrosive substances (contaminated air, ozone, gases,
solvents, acids,
alkalis, salts, radioactivity etc.) in the immediate vicinity •
No vibration or oscillation
3.2 Long-term storage
Note!
For storage or standstill periods in excess of 9 months,
Getriebebau NORD recommends the long-term storage option. With the
long-term storage option and the use of the measures listed below,
storage for up to 2 years is possible. As the actual influences on
the unit greatly depend on the local conditions, these times should
only be regarded as guide values.
Conditions of the gear unit and storage area for long-term
storage prior to commissioning: • Store in the fitting position
(see Section 6.1) and secure gear units against falling •
Transportation damage to the external paint must be repaired. Check
that a suitable rust
inhibitor is applied to the flange bearing surfaces. If
necessary apply a suitable rust inhibitor to the surfaces.
• Gear units with the long-term storage option are completely
filled with lubricant or have VCI corrosion protection agents added
to the gear oil. (See label on gear unit)
• The sealing band in the vent plug must not be removed during
storage. The gear unit must remain sealed tight.
• Store in a dry place. • In tropical regions, the drive unit
must be protected against damage by insects • Temperature must not
fluctuate beyond the range of –5 oC to +40 oC • Relative humidity
less than 60% • No direct exposure to sunlight or UV light • No
aggressive, corrosive substances (contaminated air, ozone, gases,
solvents, acids,
alkalis, salts, radioactivity etc.) in the immediate vicinity •
No vibration or oscillation
Measures during storage or standstill periods • If the relative

3.3 Transporting the gear unit
Danger!
To prevent injury, the danger area must be generously cordoned
off. Standing under the gear unit during transport is extremely
dangerous.
Attention!
Avoid damage to the gear unit. Impacts to the free ends of the
shafts may cause internal damage to the gear unit.
Use adequately dimensioned and suitable means of transportation.
Lifting tackle must be designed for the weight of the gear unit.
The weight of the gear unit can be obtained from the dispatch
documents.
3.4 Preparing for installation The drive unit must be inspected
and may only be installed if no transportation damage or leaks are
visible. In particular the radial seals and the sealing caps must
be inspected for damage. All bare metal surfaces and shafts of the
gear unit are protected against corrosion with oil, grease or
corrosion protection agents before shipping. Thoroughly remove all
oil, grease or corrosion protection agents and any dirt from the
shafts and flange surfaces before assembly. In applications where
an incorrect rotational direction may result in damage or potential
risk, the correct rotational direction of the drive shaft is to be
established by test running the drive when uncoupled and
guaranteeing such for subsequent operation. Gears with integrated
return stops are marked w
