2 Pumpdisplacement is varied by means ofpressure and/or flow Integrated PumpA unique integrated pump package isalso available. This package includes a72 or 79 l/min (19 or 21 USgpm at 1800r/min) PVE Piston pump and a 25V fixedintra-vane pump in a single inlet, doubleoutlet ported unit. This compact packageis used in a wide variety of circuits withboth fixed and variable flowrequirements. The result is lowerinstalled costs as only one mounting padand one inlet line are needed for the twoindependent and Benefits Inline, variable displacement pump Three displacement sizes displacement is varied bypressure/flow compensator controls Optional controls for maximumoperating flexibility Thru-drive available on PVE 19/21 Unique integrated pump package alsoavailable25V outletPVE outletControlPVE12 PVE19/21 PVE41/45-25 VIntegrated PumpPVE41/45 Piston pump section25V intra-vane CompensatorControl, C OptionThis control automatically varies pumpdisplacement to meet the system flowdemand for a constant system starts to reduce to zerowithin 14 bar (200 psi) of thecompensator setting.

3 Power draw-off isminimized, therefore, system reliefvalves should not be CompensatorControl with MaximumDisplacement Adjustment, CC OptionAs indicated for C option above,except there is an independent screwadjustment of maximum displacementfrom 100% (rated) to 25%. CC Note: Graphic symbols shown withexternal valve(s) and cylinder toillustrate typical Sensing Compensatorand Pressure Limiter, CVP(C) OptionThis compensator provides load sensingcontrol under all pressure conditions upto the desired maximum. It automaticallyadjusts pump flow in response to aremote pressure signal and maintainsoutlet pressure at approximately 11 bar(160 psi) above load pressure. Theintegral pressure limiter overrides theload sensing control, reducing pumpdisplacement as the preset maximumoperating pressure is reached. Overridebegins within 14 bar (200 psi) of thepreset maximum pressure compensatorsetting.

4 CVP(C) Note: Optional internal bleed orificediameter is .015 PVE with PressureCompensator Arranged forRemote Control, CG OptionExactly the same as the C (pressurecompensation option) except themachine operator is able to change thecompensator setting through the use ofa remote pilot relief valve. CG NOTEA kit is available for an electrical dualpressure compensator. This controlautomatically adjusts pump deliveryto maintain system volumerequirements at either of twopreselected operating pressuresThis allows lower settings for lowhorsepower start-up, equipmenttesting, etc. This kit also allows forhigher pressure settings as requiredin machine applications.
