Hydraulic fluidFor detailed information on the choice of hydraulic fluids andapplication conditions, please see our catalog pages RE 90220(mineral oil), RE 90221 (environmentally acceptable hydraulicfluids) and RE 90223 (HF-hydraulic fluids) prior to configuration.

The variable displacement pump AA11VO is unsuitable foroperation with HFA, HFB and HFC. When using HF- orenvironmentally acceptable (Eco-evaluated) hydraulic fluidspossible restrictions in the technical data may have to be takenin consideration. If required please consult with our technicalsupport department. The hydraulic fluide type used should bestated on the order.

Operating viscosity range

We recommend you to choose the operating viscosity (at oper-ating temperature) in the optimum range for efficiency and usefullife of

νopt = opt. operating viscosity 80...170 SUS (16...36 mm2/s)

related to the tank temperature (open circuit).

Limit viscosity range

The following values apply for borderline conditions:

νmin = 42 SUS (5 mm2/s)temporary (t < 3 min)at max. perm. temperature of tmax = 240°F (+115°C).

Note that the max. hydraulic fluid temperature of 240°F (115°C)may not be exceeded even locally (e.g. in the bearing area).

νmax = 7400 SUS (1600 mm2/s)temporary (t < 3 min)at cold start (p ≤ 435 psi (30 bar), n ≤ 1000 min-1,tmin = -40°F (-40°C)).Only for starting up without load. The optimum operatingviscosity must be reached within about 15 minutes.

Special measures are necessary in the temperature range from-40°F (-40°C) to -13°F (-25°C), please ask.

For detailed information about use at low temperatures, seeRE 90300-03-B.

Selection diagram

Explanation of selection of the hydraulic fluid

In order to select the correct fluid, it is necessary to know theoperating temperature in the tank (open circuit) in relation tothe ambient temperature.

The hydraulic fluid should be selected so that the operatingviscosity is in the optimum range (νopt) in the operatingtemperature range, see selection diagram, shaded area. Werecomm-end you to choose the respective higher viscosityclass.

Example: At an ambient temperature of X°F (°C) an operatingtemperature of 140°F (60° C) is set in the tank. In the optimumoperating viscosity range (νopt; shaded area) this correspondsto the viscosity classes VG 46 or VG 68; to be selected:VG 68.

N.B.: The leakage oil temperature, influenced by pressure andspeed, is always above the tank temperature. The temperaturemay not be higher than 240°F (115°C) at any point in themachine.

If the above conditions cannot be satisfied in the case ofextreme operating parameters or high ambient temperatures,please ask.

FiltrationThe finer the filtration the better the cleanliness class of hydraulicfluid reached, the longer the life of the axial piston unit.

To ensure functional reliability of the axial piston unit at leastcleanliness class

20/18/15 in accordance with ISO 4406 is necessaryfor the hydraulic fluid.

At very high hydraulic fluid temperatures 195°F to max. 240°F(90°C to max. 115°C) at least cleanliness class

19/17/14 in accordance with ISO 4406 is required.

If the above classes cannot be observed, please consult withproduct support.

An unrestricted, full size case drain line directly to tank isrequired.

Temperature range of the shaft sealThe FKM shaft seal is permissible for housing temperatures of-13°F to 240°F (-25°C to +115°C).

Note:For applications below -13°F (-25°C), an NBR shaft seal isnecessary as a special version (permissible temperature range:-40°F to 194°F (-40°C to +90°C)).State NBR shaft seal in clear text in the order.

Flushing the housingIf a variable displacement pump with control device EP, HD, DRor stroke limiter (H., U.) is operated over a long period(t > 10 min) with flow zero or operating pressure215 psi (< 15 bar), flushing of the housing via ports "T1", "T2"or "R" is necessary.

(L/min) 2 3 3 4 4 4 5 6

The housing flushing is unnecessary in versions with chargepump (AA11VLO), since a part of the charge flow is directed tothe housing. Higher case drain flow beyond volumetric rotarygroup losses and control flow may be noticed.

Charge pump (impeller)The charge pump is a circulating pump by which the AA11VLO(size 130...260) is filled and therefore can be operated athigher speeds. This also simplifies cold starting at lowtemperatures and high viscosity of the hydraulic fluid. Tankcharging is therefore unnecessary in most cases. A tankpressurization of max. 30 psi (2 bar) is permissible with thecharge pump.

LR Power Control

pB • Vg = constantpB = operating pressure

Vg = displacement

The precise control with a hyperbolic control characteristic,provides an optimum utilization of available power.

The operating pressure acts on a rocker via a piston.An externally adjustable spring force counteracts this,it determines the power setting.

If the operating pressure exceeds the set spring force, thecontrol valve is actuated by the rocker, the pump swivels back(direction Vg min). The lever length at the rocker is shortenedand the operating pressure can increase at the same rate asthe displacement decreases without the drive powers beingexceeded (pB • Vg = constant).

The output power (characteristic) is influenced by theefficiency of the pump.

LR Power ControlLRC Override with cross-sensingCross sensing control is a summation power control system,whereby the total power, of both the AA11VO and of a samesize AA11VO power controlled pump mounted onto thethrough drive, are kept constant.

If a pump is operating at pressures below the start of thecontrol curve setting, then the surplus power not required, in acritical case up to 100%, becomes available to the other pump.Total power is thus divided between two systems as demandrequires.

Any power being limited by means of pressure cut-off or otheroverride functions is not taken into account.

Half side cross-sensing function

When using the LRC control on the 1st pump (AA11VO) and apower-controlled pump without cross-sensing attached to thethrough drive, the power required for the 2nd pump isdeducted from the setting of the 1st pump. The 2nd pumphas priority in the total power setting.

The size and start of control of the power control of the 2ndpump must be specified for rating the control of the 1st pump.

Size 40-145: LRC

LR3 High pressure related overrideThe high pressure related power override is a total powercontrol in which the power control setting is piloted by the loadpressure of an attached fixed displacement pump (port Z).

As a result the AA11VO can be set to 100 % of the total drivepower. The power setting of the AA11VO is reduced proportio-nal to the load-dependent rise in operating pressure of thefixed displacement pump. The fixed displacement pump haspriority in the total power setting.

The measuring area of the power reduction pilot piston isdesigned as a function of the size of the fixed displacementpump.

LR Power ControlLG1/2 Pilot pressure related overrideThis power control works by overriding the control setting withan external pilot pressure signal. This pilot pressure acts on theadjustment spring of the power regulator via port Z.

The mechanically adjusted basic setting can be hydraulicallyadjusted by means of different pilot pressure settings, enablingdifferent power mode settings.

If the pilot pressure signal is then adjusted by means of aexternal power limiting control, the total hydraulic powerconsumption of all users can be adapted to the available drivepower from the engine.

The pilot pressure used for power control is generated by anexternal control element that is not a component part of theA11VO (e.g. see also data sheet RE 95310, Electronic LoadLimiting Control, LLC).

LRE Power control with pressure cut-off,2-stage

By connecting an external pilot pressure to port Y, the basicvalue of the pressure cut-off can be increased by 725 +290 psi(50 +20 bar) and a 2nd pressure setting implemented.

This value is usually above the primary pressure relief valvesetting and therefore disables the pressure cut-off function.

The pressure signal at port Y must be between 290 and 725 psi(20 and 50 bar).

Characteristic: LRE

LRD Power control with pressure cut-offPressure cut-of is a pressure control that adjusts the pumpdisplacement back towards Vg min when a preset pressurevalue is reached.

This function overrides the power control, i.e. below the presetpressure value, the power function is effective.

LRDS Power control with pressure cut-off and load sensing

The load-sensing control is a flow control option that operatesas a function of the load pressure to regulate the pumpdisplacement to match the actuator flow requirement.

The flow depends here on the cross section of the externalsensing orifice (1) fitted between the pump outlet and theactuator. The flow is independent of the load pressure belowthe power curve and the pressure cut-off setting and within thecontrol range of the pump.

The sensing orifice is usually a separately arranged loadsensing directional valve (control block). The position of thedirectional valve piston determines the opening cross sectionof the sensing orifice and thus the flow of the pump.

The load-sensing control compares pressure before and afterthe sensing orifice and maintains the pressure drop across theorifice - and therefore the pump flow - constant as a function ofthe orifice size.

If the differential pressure ∆p increases, the pump is swivelledback towards Vg min and, if the ∆p decreases the pump isswivelling out towards Vg max until the pressure drop across thesensing orifice in the valve is restored.

∆porifice = ppump – pactuator

The setting range for ∆p is between 200 psi and 360 psi (14 barand 25 bar).

The standard differential pressure setting is 260 psi (18 bar).(Please state in clear text when ordering).

The stand-by pressure in zero stroke operation (sensing orificeplugged) is slightly above the ∆p setting.

In a standard LS system the pressure cut-off is integrated inthe pump control. In a LUDV (flow sharing) system thepressure cut-off is integrated in the LUDV control block.

(1) The sensing orifice (control block) is not included in thepump supply.

LR Power ControlLR... Power control with stroke limiterThe stroke limiter can be used to vary or limit the displacementof the pump continuously over the whole control range. Thedisplacement is set in LRH with the pilot pressure pSt (max.580 psi (40 bar)) applied to port Y or in LRU by the controlcurrent applied to the proportional solenoid. A DC current(PWM) of 12V (U1) or 24V (U2) is required to control theproportional solenoid.

The power control overrides the stoke limiter control, i.e. belowthe hyperbolic power characteristic, the displacement iscontrolled, by the control current or pilot pressure. Whenexceeding the power characteristic with a set flow or loadpressure, the power control overrides and reduces thedisplacement following the hyperbolic char acteristic.

To permit operation of the pump displacement control from itsstarting position Vg max to Vg min, a minimum control pressure of435 psi (30 bar) is required for the electrical stroke limiterLRU1/2 and the hydraulic stroke limiter.

The required control oil is taken either from the load pressure,or from the externally applied control pressure at the G port.

To ensure functioning of the stroke limiter at low operatingpressure as well, the port G must be supplied with externalcontrol pressure of approx. 435 psi (30 bar).

Note:If no external control pressure is connected at G, the shuttlevalve must be removed.

DR Pressure ControlDRL Pressure control for parallel operationThe pressure control DRL is suitable for pressure control ofseveral axial piston pumps AA11VO in parallel operationpumping into a common pressure header.

The parallel pressure control has a pressure rise characteristicof approx. 215 psi (15 bar) from qv max to qv min. The pumpregulates therefore to a pressure dependent displacementposition. This results in stable control behavior, without theneed of "staging" the individual pump compensators.

With the externally installed pressure relief valve (1) the nominalpressure setting of all pumps connected to the system isadjusted to the same value.


Each pump can be individually unloaded from the system by anseparately installed 3/2-way directional valve (2).

The check valves (3) in the service line (port A) or control line(port X) must be provided generally.

The external valves are not included in the pump supply.

As a separate pressure relief valve (1) we recommend:

DBDH 6 (manual control) see RE 25402

The size of the remote relief valve depends on the number ofpumps installed in parallel, and has to be able to handle thesum of the pilot flows provided by each pump control.

With the electrical control with proportional solenoid, the pumpdisplacement is adjusted proportionally to the solenoid current,resulting in a magnetic control force, acting directly onto thecontrol spool that pilots the pump control piston.

A 12V ( EP1) or 24 V (EP2) DC supply is required to operatethe proportional solenoid.

Control from Vg min to Vg max

With increasing control current the pump swivels to a higherdisplacement.

Starting position without control signal (control current):– at operating pressure and external control pressure

< 435 psi (30 bar): Vg max


A control pressure of 435 psi (30 bar) is required to swivel thepump from its starting position Vg max to Vg min .

The required control pressure is taken either from the loadpressure, or from the externally applied control pressure at theG port.

To ensure the control even at low operating pressure < 435 psi(30 bar) the port G must be supplied with a external controlpressure of approx. 435 psi (30 bar).

Note:If no external control pressure is required at G port, the parts ofthe shuttle valve are to be removed from the pump and G portmust be plugged.

Note:Install pump with EP control in the oil tank only when usingmineral hydraulic oils and an oil temperature in the tank of max.180° F (80° C).

The following electronic control devices are available forcontrolling the proportional solenoid:

– Proportional analog amplifier PV (see RE 95023)

– Digital electronic control unit RC (see RE 95200)

EP Electrical Control With Proportional SolenoidEP.D Electrical control with pressure cut-offThe pressure cut-off corresponds to a pressure control whichadjusts the pump displacement back to Vg min, when thepressure setting is reached.

This function overrides the EP control, i.e. the control currentrelated displacement control is functional below the pressuresetting.

The valve for the pressure cut-off is integrated in the controlhousing and is set to a fixed specified pressure value at thefactory.

Installation and Commissioning InstructionsGeneral

The pump housing must be filled with hydraulic fluid during commissioning and before operation (filling of housing case).Commissioning must take place at low speed and without load until the system has been bled completely.

In long periods at standstill the housing can empty via the service lines, sufficient filling of the housing must be guaranteed whenrestarting.

The case drain for the pump housing cavity must be drained into the tank through the highest leakage oil port. The minimumsuction pressure at port S of 12 psi (0.8 bar) absolute (without charge pump) or 8.5 psi (0.6 bar) (with charge pump) may not bedropped below of.

Installation below tank

Pumps under minimum oil level in the tank (standard).

– any installation position.

– installation position "shaft upwards":

Make sure that the pump housing is completely filled duringcommissioning. An air cushion in the area of the bearingscauses damage to the axial piston unit.

Measures:

– Fill the axial piston pump via the highest leakage oil port T1,T2, R prior to commissioning.

– Recommendation: fill suction lines.

– Operate the pump at low speed (starter speed) until thepump is completely filled.

– Minimum immersion depth of the suction or leakage oil linein the tank: 7.87 in (200 mm) (related to the min. oil level inthe tank).

Installation above tank

Pumps above minimum oil level in the tank.

The housing cavity may empty via the service lines duringlong periods of standstill (air gets in through the shaft seal),the bearing is not adequately lubricated when restarting.The axial piston unit must be filled via the highest leakage oilport prior to restarting (bleed via port R). Emptying via theleakage oil line can be prevented with a check valve in theleak oil line (opening pressure7.5 psi (0.5 bar). Emptying via the service ports can bereduced with a special version of the control plate.

– installation position "shaft horizontal" and "shaft upwards".

– installation position "shaft upwards".

– The version AA11VLO (with charge pump) is not designedfor installation above the tank.

See installation below tank for further measures.

Additional measures for installation above the tank:

– max. permissible suction height hmax = 31.5 in (800 mm)

– min. permissible pressure at port S (min. suction pressure)

– For control options with pressure control, displacementlimiters, HD and EP control, the minimum displacementsetting must be Vg ≥ 5% • Vg max.

– Recommendation: use suction line with "goose neck".


Safety Instructions– The pump AA11VO is designed for using in an open circuit.

– Configuration, assembly, commissioning of the pump must be performed by trained and qualified personnel.

– The operating and function ports are designed exclusively for connecting hydraulic lines.

– Tightening torques: The tightening torques specified in this data sheet are maximum values and may not beexceeded (maximum value for screw thread). Manufacturer specifications for the max.permissible tightening torques of the used fittings must be observed!

For DIN 13 fastening screws we recommend checking the tightening torque individuallyaccording to VDI 2230 Edition 2003.

– Caution: Thread depth of the S and A/B port UNC bolt holes do not conform to SAE standards on all pump sizes. Shortenedbolts and or "high collar" lock washers may be required. See installation drawing for full thread depth.

– There is a danger of burns from the pump and especially the solenoids during and shortly after operation.

– Observe the specified data and instructions.
