Hydraulic fluidFor detailed information on the choice of hydraulic fluidsand application conditions, please see our catalog pagesRE 90220 (mineral oil), RE 90221 (environmentally acceptablehydraulic fluids) and RE 90223 (HF-hydraulic fluids) prior toconfiguration.
The variable displacement pump A11VO 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 (atoperating temperature) in the optimum range for efficiency anduseful life of
opt = opt. operating viscosity 16...36 mm2/s
related to the tank temperature (open circuit).
Limit viscosity range
The following values apply for borderline conditions:
min = 5 mm2/stemporary (t < 3 min)at max. perm. temperature of tmax = +115C.
Note that the max. hydraulic fluid temperature of 115C maynot be exceeded even locally (e.g. in the bearing area).
max = 1600 mm2/stemporary (t < 3 min)at cold start (p 30 bar, n 1000 min-1, tmin = -40C).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-40C to -25C, please ask.
For detailed information about use at low temperatures, seeRE 90300-03-B.
Selection diagram
Explanation of selection of the hydraulic fluid
Knowledge of the operating temperature in the tank (opencircuit) depending on the ambient temperature is a prerequisitefor the correct choice of hydraulic fluid.
The hydraulic fluid should be selected so that the operatingviscosity is in the optimum range (opt) in the operatingtemperature range, see selection diagram, shaded area.We recommend you to choose the respective higher viscosityclass.
Example: At an ambient temperature of X C an operatingtemperature of 60 C is set in the circuit. In the optimumoperating viscosity range (opt; shaded area) this correspondsto the viscosity classes VG 46 or VG 68; to be selected:VG 68.
Note: The leakage oil temperature, influenced by pressure andspeed, is always above the tank temperature. The temperaturemay not be higher than 115C at any point in the machine.
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 ofhydraulic fluid reached, the longer the life of the axial pistonunit.
To ensure functional reliability of the axial piston unit at leastcleanliness class
20/18/15 in accordance with ISO 4406 is necessary forthe hydraulic fluid.
At very high hydraulic fluid temperatures (90C to max. 115C)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.

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

The housing flushing is unnecessary in versions with chargepump (A11VLO), 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 with which the A11VLO(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 a max. 2 bar is permissible with charge pump.

LR Power ControlThe power control regulates the displacement of the pumpdepending on the operating pressure so that a given drivepower is not exceeded at constant drive speed.
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 A11VO and of a samesize A11VO power controlled pump mounted onto the throughdrive, 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 (A11VO) 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 A11VO can be set to 100 % of the total drivepower. The power setting of the A11VO 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).

Power control with negative override, LG1: the force resultingfrom the pilot pressure is acting against the mechanicaladjustment spring of the power control.
Increasing the pilot pressure reduces the power setting.

LE1/2 Electrical override (negative)Contrary to hydraulic power control override, the basic powersetting is reduced by an electrical pilot current applied to aproportional solenoid. The resulting force is acting against themechanical power control adjustment spring.
Increase in current = decrease in power
If the pilot current signal is adjusted by a load limiting control(e.g. LLC control RE 95310) the power consumption of allmechanical and hydraulic actuators is decreasing the A11VOpower setting to match the remaining available power from theengine.
A 12V (LE1) or 24V (LE2) supply is required for the control ofthe proportion solenoid.

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 50 +20 barand 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 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.
The pressure cut-off function is integrated into the pumpcontrol module and is preset to a specified value at the factory.
Setting range from 50 to 350 bar

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.

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. 40bar) applied to port Y or in LRU by the control current appliedto the proportional solenoid. A DC current of 12V (U1) or 24V(U2) is required to control the proportional 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 characteristic.
To permit operation of the pump displacement control from itsstarting position Vg max to Vg min, a minimum control pressure of30 bar is required for the electrical stroke limiter LRU1/2 andthe 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. 30 bar.
Note:If no external control pressure is connected at G, the shuttlevalve must be removed.

DR Pressure ControlDR Pressure controlThe pressure control keeps the pressure in a hydraulic systemconstant within its control range even under varying flowconditions. The variable displacement pump only moves asmuch hydraulic fluid as is required by the actuators. If theoperating pressure exceeds the setpoint set at the integralpressure control valve, the pump displacement is automaticallyswivelled back until the pressure deviation is corrected.
In zero pressure non-running condition, the pump is swivelledto its starting position (Vg max) by means of the control spring.
Setting range from 50 to 350 bar.

DRS Pressure control with load sensingThe 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 pressure cut-off setting and within the control range of thepump.
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 pactuatorThe setting range for p is between 14 bar and 25 bar.
The standard differential pressure setting is 18 bar. (Pleasestate in clear text when ordering).
The stand-by pressure in zero stroke operation (sensing orificeplugged) is slightly above the p setting.
(1) The sensing orifice (control block) is not included in thepump supply.

DR Pressure ControlDRG Pressure control, remote controlledThe remote control pressure cut-off regulator permits theadjustment of the pressure setting by a remotely installedpressure relief valve (1). Pilot flow for this valve is provide by afixed orifice in the control module. The pressure drop acrossthis relief valve is additive to the spring bias of the controlspool.
Setting range from 50 to 350 bar.
In addition the pump can be unloaded into a standby pressurecondition by an externally installed 2/2-way directional valve(2).
Both functions can be used individually or in combination (seecircuit diagram).
The external valves are not included in the pump supply.
As a separate pressure relief valve (1) we recommend:

DR Pressure ControlDRL Pressure control for parallel operationThe pressure control DRL is suitable for pressure control ofseveral axial piston pumps A11VO in parallel operationpumping into a common pressure header.
The parallel pressure control has a pressure rise characteristicof approx. 15 bar from qv max to qv min. The pump regulatestherefore to a pressure dependent displacement position. Thisresults in stable control behavior, without the need 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.
Setting range from 50 to 350 bar.
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.
