Introduction
The Vickers Integrated Motor Pump is aunique combination of a conventionalAC induction motor cooled with systemhydraulic oil and a Vickers hydraulicpump, either fixed vane pump orvariable piston type, housed in a specialsound reduction enclosure.
This combination provides anexceptionally quiet and small pumpingpackage for any industrial applicationrequiring up to 125 horsepower (92kilowatts) of continuous hydraulic power.
The package comes completelyassembled, tested, and ready forinstallation.
Circulating the hydraulic oil through themotor, bathing both the rotor and stator,makes it possible to obtain twice thenormal continuous output power fromthe motor windings. Physical sizereductions of 35% to 50% comparedwith conventional pumping packagesare possible as a result. Normaloperation of the motor is not affected bycirculating oil through it, nor is thesystem’s hydraulic oil damaged.
Heat generated within the electric motoris carried away by the hydraulic fluidand dissipated by the hydraulic coolingsystem. A motor fan is not needed,
which makes it practical to cover theentire assembly (motor and pump) witha compact, polyethylene soundreduction enclosure. This reduces thesound from the pump as well as themotor, resulting in a noise levelreduction that is unsurpassed in theindustry.
A complete line of standard Vickerspumps can be fitted to the IntegratedMotor Pump including single fixed vanepumps, single variable piston pumps,double vane pumps, double pistonpumps or mixed vane and pistoncombinations.
Features & Benefits� Smaller package size because of oil
cooled electric motor.
� Heat generated by the electric motor iscarried away by the hydraulic fluid.
� 70% reduction in sound compared toconventional power unit systems(approximately 10 dBA).
� All external leakage points for both oilleaking out and air leaking in aresealed by static o-rings.
� External leakage from dynamic shaftseals has been eliminated.
� The specially designed couplingconnecting the pump and motor driveshafts is oil lubricated and factoryinstalled by Vickers. This eliminateslabor to align and install the coupling.
� Only normal filtration practices arerequired.
� Meets the requirements ofInternational Standard IEC 34-5(1991-01) for IP57 degrees ofprotection when installed using asealed electrical conduit.
� The electric motor stator componentshave UL recognition.
� Motor bearings are continuouslylubricated by hydraulic fluid.
� System sound is significantly reducedby eliminating the fan and enclosingthe motor and pump.

General Information
Vickers oil-cooled Motor Pumpscombine hydraulic and electricaltechnologies into a single package ratedtwo times higher than conventionalair-cooled motor units of the same size.Operating the electric motor at thesehigher levels results in a lighter weight,more compact unit for the samehydraulic power output.
Because heat generated in the motor iscarried away by the oil, it is possible toenclose the pump and motor, providinga total pumping package withunsurpassed low sound levels.
Electrical supply equipment for theoil-cooled Integrated Motor Pumps isidentical to conventional air-cooled AC motors.
ComponentsShroudThe acoustic shroud is made of durablepolyethylene plastic, impervious tocommon industrial coolants andhydraulic fluids. The speciallyengineered material dampens sound.
PumpsThe Integrated Motor Pump can beconfigured with a variety of Vickerspumps:
� Single and double variable pistonpumps with load sensing or pressurecompensating controls.
� Single and double vane pumps.
� Double pumps with one variabledisplacement piston pump and onefixed vane pump.
Cooling OperationHydraulic oil, at low velocity, first flowsthrough the electric motor, around therotor, stator poles, and winding,removing heat. Oil then passes to theinlet of the pump, to the load, andthrough the hydraulic system.
The cooling properties of oil (heattransfer coefficient and specific heat)are superior to those of air by a fullorder of magnitude. The IntegratedMotor Pump system can thereforemaintain rotor and stator windingtemperatures significantly lower thanthose in air-cooled motors, while raisingthe oil temperature only a few degreesfrom inlet to outlet.
Sound ComparisonsThe following chart illustrates thedramatic reduction in airborne noiseprovided by the Integrated Motor Pumpin typical power unit applications.

The Integrated Motor Pump has verylow sound levels, but it is necessary todesign power units with proper soundreduction techniques such as isolationof the Integrated Motor Pump from thepower unit base, proper use of hose andtubing, and isolation of structuralelements of the power unit which couldamplify sound. Refer to Vickersliterature #510, Noise Control inHydraulic Systems, for designguidelines.

B Conventional 1800 rpm, 60 Hz 60 hp, air-cooled electricmotor and PVH57 pump
C Integrated Motor Pump1800 rpm, 60 Hz60 hp, oil-cooled electricmotor and PVH57 pump
ApplicationThe unit is delivered fully assembledand tested. There is no motor couplingor bellhousing requiring assembly.
The Integrated Motor Pump uses astatic o-ring sealed flange to eliminateany potential leakage.
Pump to Motor AlignmentThe motor shaft on the Integrated MotorPump is machined with a spline. Pumpsfitted to the motor are also supplied withsplines. An internal splined couplingconnects the motor to the pump.
Motor to pump coupling
Motor Pump
o-ring
This coupling mechanism, used inconjunction with the machined mountingflange, provides for precise alignment ofthe pump to the motor. Vibration isminimized as a result.
If it becomes necessary to remove orreplace a pump for any reason, precisealignment is achieved without the needto indicate shafts and separately alignthe pump to the motor.
The entire area around the splinedcoupling is bathed in oil and sealed by astatic o-ring seal formed by themounting flange and the pump itself. Inaddition, any minute shaft seal leakagefrom the pump stays within the sealedmotor.
Inlet Condition
Standard models require a positive inletpressure, normally provided by using anoverhead reservoir (Figure 1) or an “L”shaped reservoir (Figure 2) with its oillevel up to the motor pump air bleed portconnection. The maximum positive inletpressure is 2 bar (29 psi).
Vickers recommends a positive inletpressure for all Integrated Motor Pumpinstallations.
NOTE: Prior to start-up, the electricmotor should be filled with hydraulic fluid
until the oil level reaches the air bleedconnection as shown in Figures 1 and 2.This will ensure proper oil cooling of thestator winding.

CAUTIONDo not attempt to lift or move thisunit using the sound shroud. Thiscould cause damage to the plasticenclosure. Use the lifting eye-bolts.
Wire Sealing ConnectorIn conventional air-cooled motors, thestator wires are brought out of the motorhousing into a terminal box for hook up.
In the Integrated Motor Pump, a customoil tight connector is used to bring thewires out to the terminal box. Theconnector consists of a flange with amolded center section (see below). Themolded center section is actually acontinuation of the wire insulation, sothere is no leakage point or jointbetween the flange and the wires asthey pass through the flange.

The three lead wires used to connectthe electrical service are the same sizeas those used for the same current witha standard air-cooled motor.
Phasing
The motor lead wires are labeled #1, #2,and #3. Correct direction of rotationrequires that they be connected to the3-phase, NEMA Code F rating serviceas follows:
#1 to phase A#2 to phase B#3 to phase C
Because the motor pump shaft iscompletely enclosed, it is not possible tocheck the direction of rotation visually.Vickers recommends use of a phasemeter* in connecting the power service,to assure correct rotation. Prolongedrunning in the wrong direction mightresult in equipment damage.

Cooling Capacity
Cooling provisions with the VickersIntegrated Motor Pump differ fromconventional systems in two respects:
1. Electrical losses in the motor arecooled by the hydraulic fluid ratherthan by a fan on the motor. Thiseliminates one noise source (the fan)and permits complete enclosure of themotor and pump for further noisereduction. In addition, because oil is10 times more effective than air as acoolant, the operating current (power)can be increased without overheatingthe motor. The Integrated Motor Pumpcan, therefore, use a more compactmotor than an air-cooled unit with thesame power rating and achieve asmaller package size.
2. Hydraulic fluid in the motor causesmore drag torque than does air in aconventional motor. The difference,offset in part by the power savedthrough eliminating a fan, is the onesmall but real penalty in operating anIntegrated Motor Pump.
Electrical losses vary with the inputpower actually used in an application.The following curves show the totalelectrical losses for each size MotorPump, as a function of the input power.The input power is the sum of the pumpinput plus electrical losses and draglosses. These curves are the same foreither 1500 rpm (50 Hz) or 1800 rpm (60 Hz) models.
Fluid drag torque varies with fluidviscosity. This loss depends on fluidtype and temperature, but not on inputpower. Page 7 shows drag losses withtypical fluids (ISO grades VG22, VG32and VG46) at temperatures from 30� to60�C (86� to 140�F). These losses arelower at 1500 rpm than at 1800 rpm,shown in the separate curves.
The heat generated in a hydraulic circuitis the sum of all component losses,including head losses in fittings and fluidconductors, plus throttling losses inpressure and flow control valves. Acommon design provision is 20% of theinstalled hydraulic power. If the dutycycle is well defined, a more specificestimate based on detailed analysis orexperience with similar systems may bemade.
The cooling capacity needed in asystem using a Vickers Integrated MotorPump is:
Heat generated in the circuit+ Electrical loss + Drag loss= Total cooling required

� Select a PVH57 and the corresponding Motor Pump model:
MP45-B1-R-P57C-A-F1-20
� Determine average input power:

Sound Level Data
Determining Sound Levelsof the Integrated MotorPumpSound pressure levels for the completeline of Integrated Motor Pumps areshown in tables on the following pages:
The tabulated data shows sound levelsfor the complete motor pump packages,by specific pump size at specificoperating pressures.
Single Pumps
Select the motor pump size (MP**) forthe application. Locate the pumpdisplacement in the cm3/rev column andmove down the table to the desiredoperating pressure. The sound level indB(A) represents the complete motorpump package.
Example: A MP15, using a PVQvariable piston pump with adisplacement of 32 cm3/rev operating at1800 rpm and 70 bar (1000 psi) willhave a sound level of 64 dB(A).
Double Pumps
Select the motor pum p size based onthe two pumps with the requireddisplacements and operating pressures.Refer to the appropriate motor pumpsound level table and read the soundlevels for both pumps. To combine thesetwo sound levels, subtract the lowerlevel from the higher and use the graphshown (upper right) to calculate thesound level of the motor pump package.This procedure also applies to doublevane pumps.
Example: The 1800 rpm MP75 motorpump is chosen using a thru-drivePVH57 variable piston pump (57cm3/rev) at 210 bar (3000 psi) and aPVQ40 (40 cm3/rev) at 175 bar (2500psi). The two sound levels from theMP75 table are 74 dB(A) and 68 dB(A)respectively. Subtracting the lower levelfrom the higher results in a 6 dB(A)difference. The graph shows that for adifference of 6 dB(A), 1 dB(A) should beadded to the higher level sound (74).The combined value is75 dB(A).
* NOTE: To find the shaft power to drive a single piston pump or vane pump at 1800 rpm, select the required displacement and operatingpressure, then read across the chart for the kilowatt power input.To determine the total input power for thru-drive pumps, add the kilowatts for the front pump and the rear pump together, at the selectedoperating pressures. The input kilowatts should not exceed 16 kW with only one pumping unit in operation, or with two pumping units inoperation simultaneously.
For example: A thru-drive pump with a displacement of 20 cm3/rev will require 8 kW of power at 100 bar (1500 psi).The second pump with a displacement of 18 cm3/rev will require 7 kW of power at 100 bar (1500 psi).With both pumping units operating simultaneously, they require 15 kW of input power.
�1. As operating pressure reduces to minimum, flow increases from chart values by approximately 4 to 5% for piston pumpsand 10 to 12% for vane pumps.
2. As the motor pump reaches full load, the motor speed droop will reduce output flow from chart values by approximately 2%.
* NOTE: To find the shaft power for a double vane pump at 1800 rpm, select the displacement and operating pressure for the shaft end andcover end pumps separately, read the kilowatt power input for each, and add the two together. If the shaft end and cover end pumps will not beloaded simultaneously, find the maximum sum of the two power requirements, considering their load cycles separately.

Mounting Rails
The motor pump mounting sets shown(right) provide convenient installationcombined with effective isolation ofstructure-borne noise, or mechanicalvibration.
Two sets are offered for each motorpump size. One is for single pump orlightweight double pump models, anda second for two-pump models inwhich the pump weight requires anoutboard support to reduce theoverhung load on the pump mountingflange.
The Vickers mounting sets helpensure low noise for the entire system,reflecting the quiet operation of themotor pump.

Fluid Cleanliness
Proper fluid condition is essential forlong and satisfactory life of hydrauliccomponents and systems. Hydraulicfluid must have the proper cleanlinessand chemical composition for protectionagainst wear of components.
Essential information on themaintenance of hydraulic fluid isincluded in Vickers publication 561;“Vickers Guide to SystemicContamination Control,” available fromyour local Vickers distributor or bycontacting Vickers, Incorporated.Recommendations on filtration and theselection of products to control fluidcondition are included in 561.
Recommended cleanliness levels, usingpetroleum oil under common conditions,are based on the highest fluid pressurelevels in the system and are coded inthe chart below. Fluids other thanpetroleum, severe service cycles ortemperature extremes are cause foradjustment of these cleanliness codes.See Vickers publication 561 for exactdetails.
Vickers products, as any components,will operate with apparent satisfaction in
fluids with higher cleanliness codes(higher levels of contamination) thanthose prescribed. Other manufacturersmay recommend levels above thosespecified. Experience has shown,however, that life of any hydrauliccomponents is shortened in fluids withhigher cleanliness codes than thoselisted below. These codes have beenproven to provide a long trouble-freeservice life for the products shown.
