SymbolPPPPS LS LS LS LMSingle pumpDouble pumpMotor-pump-drive unitFunction, sectionDesignThe PV7 hydraulic pumps are variable displacement vane pumps.They mainly consist of the housing (1), rotor (2), vanes (3), stator ring(4), pressure controller (5) and adjustment screw (6).The circular stator ring (4) is retained between the small control piston(10) and the large control piston (11). The third contact point of thering is the height adjustment screw (7).The driven rotor (2) rotates inside the stator ring (4). The vanescontained within the rotor are pressed against the stator ring (4) bycentrifugal force.AdjustmentAt the same time as the system pressure builds up, the rear surfaceof the small control piston (10) is connected to the system via achannel and is, therefore always subjected to the system pressure.When the pump is in its displacement position, the rear surface ofthe large control piston (11) is also subjected to the system pressurevia a drilling in the control piston (14). The control piston (11) withthe larger surface area holds the stator ring (4) in its eccentric position.The pumps displaces fluid at a pressure that is lower than the zerostroke pressure set on the pressure controller (5).The control piston (14) is held in a certain position by a spring (13).X–X19X2961087341112PLSXSuction and displacement processThe chambers (8) which are required for the transport of the fluid areformed by the vanes (3), the rotor (2), the stator ring (4) and thecontrol plates (9).In order to ensure the pump function during commissioning, the statorring (4) is held in the eccentric position (displacement position) bythe spring (12) which is behind the large control piston (11).PV7Due to the rotation of the rotor (2), the chambers (8) increase in sizeand at the same time, fill with fluid via the suction channel (S). Whenthe maximum chamber volume is reached, the chambers (8) aredisconnected from the suction side. As the rotor (2) continues torotate, they are connected to the pressure side and become smallerand press the pressure fluid into the system via the pressure channel(P).3/32RE 10 515/05.00
FunctionOff-strokeIf force FP, resulting from the product of pressure x area, exceeds thecounter force FF of the spring, the controller piston (14) is movedagainst the spring (13). In this way, the chamber behind the largecontrol spool (11) is connected to tank and is thus unloaded.The small control piston (10), which is constantly under systempressure, moves the stator ring (4) towards the centre position, virtuallythe zero position. The pump maintains the pressure, the flow decreasesto zero, leakages are compensated for.Power loss and heating of the fluid are kept at a low level.The qV-p-characteristic curve runs vertically and shifts in parallel ashigher pressures are set.FP14513FFPTankSystem pressurePilot pressure104S11FPOn-strokeWhen the pressure in the system falls below the set zerostroke pressure, the spring (13) moves the contol piston(14) back to its inital position.The large control piston (11) is subjected to pressure andmoves the stator ring (4) into the eccentric position. Thepump is in its displacement position.14513FFPTankSystem pressure10RE 10 515/05.004S114/32PV7

LockMaterial No.: 00844598This lock is fitted to all pumps which have the controller option 3 , 7 or 8 .Functional descriptionAfter unlocking (by turning the key clockwise) the enire lock covercan be removed from the control. The control adjuster is thenaccessible.To lock, the lock cover is placed over the control adjuster and thenpressed home, the lock cylinder is pressed down and the key turnedin an anti-clockwise direction.A lock can be fitted to a standard pump by,– Unscrewing the domed nut from the control adjuster.– Fitting the nut which contains the lock.– Fitting the lock cover as described in the functional description.Engineering guidelines for combination pumps– The PV7 pumps are, as standard, capable of being combined.Each pump is fitted with a splined second shaft end.– When operating the PV7 pump, as a fixed displacement unit,the fixed displacement unit must be the rear pump.– The general technical data is the same as with the single pumps(see page 5).– The pump with the higher load (pressure x flow) should be thefirst pump stage.– When combining several pumps, the torques produced canreach excessively high values.The sum of the torques must not exceed the permissible values(see table)– Combination parts have to be a separate item on an order.– The necessary seals and screws are included in the combinationkit.Single pumpCombination pumpT1TmaxTmaxTabmaxfrommaxPV7Build size1016254063100Max. permissibleDrive torque TmaxOutput torque Tfrom max90140180280440680457090140220340T2Tab1from 11st pumpCombination pump:Required max. pressure:T T12nd pumpTab2from 2P2V7/25-30 V7/25-30 pn 160 bar p V 0.0159(Nm)ηhydr.-mech.T1.2 160 30 0.0159(Nm)0.85T1.2 90 Nm Tfrom maxCalculation exaple:V Displacement in in cm3ηhydr.-mech.

The PV7 hydraulic pumps are variable displacement vane pumps. They mainly consist of the housing (1), rotor (2), vanes (3), stator ring (4), pressure controller (5) and adjustment screw (6). The circular stator ring (4) is retained between the small control piston (10) and the large control piston (11). The third contact point of the
