Hydraulic fluidBefore starting project planning, please refer to our data sheets RE 90220 (mineral oil), RE 90221 (environmentally acceptable hydraulic fluids) and RE 90223 (HF hydraulic fluids) for detailed information regarding the choice of hydraulic fluid and operating conditions.

The variable pump AA11VO is not suitable for operating with HFA, HFB and HFC. If HFD or environmentally accept-able hydraulic fluids are being used, the limitations regarding technical data and seals mentioned in RE 90221 and RE 90223 must be observed.

When ordering, indicate the hydraulic fluid that is to be used.

Operating viscosity range

For optimum efficiency and service life, select an operating vis-cosity (at operating temperature) within the optimum range of

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

depending on the tank temperature (open circuit).

Limits of viscosity range

The limiting values for viscosity are as follows:

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

νmax = 7400 SUS (1600 mm2/s) Short-term (t < 3 min) At cold start (p ≤ 435 psi (30 bar), n ≤ 1000 rpm, tmin = -40 °F (-40 °C)). Only for starting up without load. Optimum operating viscosity must be reached within approx. 15 minutes.

Note that the maximum hydraulic fluid temperature of 240 °F (115 °C) must not be exceeded locally either (e.g. in the bear-ing area). The temperature in the bearing area is – depending on pressure and speed – up to 9°F (5 K) higher than the aver-age case drain temperature.

Special measures are necessary in the temperature range from -40 °F (-40 °C) and -13 °F (-25 °C) (cold start phase) , please contact us.

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

Details regarding the choice of hydraulic fluid

The correct choice of hydraulic fluid requires knowledge of the operating temperature in relation to the ambient temperature: in an open circuit the tank temperature.

The hydraulic fluid should be chosen so that the operating vis-cosity in the operating temperature range is within the optimum range (νopt.) – see the shaded area of the selection diagram. We recommended that the higher viscosity class be selected in each case.

Example: At an ambient temperature of X °C an operating temperature of 140 °F (60 °C) is set. In the optimum operating viscosity range (νopt; shaded area) this corresponds to the viscos-ity classes VG 46 and VG 68; to be selected: VG 68.

Note The case drain temperature, which is affected by pressure and speed, is always higher than the tank temperature. At no point in the system may the temperature be higher than 240 °F (115°C).

If the above conditions cannot be maintained due to extreme operating parameters, please contact us.

FiltrationThe finer the filtration, the higher the cleanliness level of the hy-draulic fluid and the longer the service life of the axial piston unit.

To ensure functional reliability of the axial piston unit, the hy-draulic fluid must have a claenliness level of at least20/18/15 according to ISO 4406.

At very high hydraulic fluid temperatures (195 °F (90 °C) to maximum 240 °F (115 °C), at least cleanliness level 19/17/14 according to ISO 4406 is required.

If the above classes cannot be observed, please contact us.

Temperature range of the shaft seal ringThe FKM shaft seal ring is permissible for case drain tempera-tures of -13 °F to 240 °F (-25 °C to +115 °C).

NoteFor applications below-13 °F (-25 °C), an NBR shaft seal ring is necessary (permissible temperature range: -40 °F to 194 °F (-40 °C to +90 °C). State NBR shaft seal ring in clear text in the order.

Flushing the caseIf a variable pump with control unit EP, HD, DR or stroke limiter (H., U., ) is operated over a long period (t > 10 min) with flow zero or operating pressure < 220 psi (15 bar), flushing of the case via ports "T1", "T2" or "R" is necessary.

Flushing the case is unnecessary in versions with charge pump (AA11VLO), since a part of the charge flow is directed to the case.

Charge pump (impeller)The charge pump is a circulating pump with which the AA11VLO (size 130 to 260) is filled and therefore can be operated at higher speeds. This also simplifies cold starting at low temperatures and high viscosity of the hydraulic fluid. Tank charging is therefore unnecessary in most cases. A tank pres-sure of a maximum 30 psi (2 bar) is permissible with charge pump.

LR – Power controlThe power control regulates the displacement of the pump de-pending on the operating pressure so that a given drive power 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 measuring piston. An externally adjustable spring force counteracts this, it determines the power setting.

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

The hydraulic output power (characteristic LR) is influenced by the efficiency of the pump.

State in clear text in the order:

drive speed n in rpm –

maximum flow q – V max in l/min

LRC Override with cross sensingCross sensing control is a summation power control system, whereby the total power, of both the AA11VO and of a same size AA11VO power controlled pump mounted onto the through drive, are kept constant.

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

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

Half side cross sensing function

When using the LRC control on the 1st pump (AA11VO) and a power-controlled pump without cross sensing attached to the through drive, the power required for the 2nd pump is deducted from the setting of the 1st pump. The 2nd pump has priority in the total power setting.

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

LR – Power controlLR3 High-pressure related overrideThe high-pressure related power override is a total power control in which the power control setting is piloted by the load pressure of an attached fixed pump (port Z).

As a result the AA11VO can be set to 100 % of the total drive power. The power setting of the AA11VO is reduced propor-tional to the load-dependent rise in operating pressure of the fixed pump. The fixed pump has priority in the total power setting.

The measuring area of the power reduction pilot piston is desi-gned as a function of the size of the fixed pump.

LR – Power controlLG1/2 Pilot-pressure related overrideThis power control works by overriding the control setting with an external pilot pressure signal. This pilot pressure acts on the adjustment spring of the power regulator via port Z.

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

If the pilot pressure signal is then adjusted by means of an external power limiting control, the total hydraulic power consumption of all users can be adapted to the available drive power from the engine.

The pilot pressure used for power control is generated by an external control element that is not a component part of the AA11VO (e.g. see also data sheet RE 95310, Electronic Load Limiting Control, LLC).

LE1/2 Electric override (negative)Contrary to hydraulic power control override, the basic power setting is reduced by an electric pilot current applied to a proportional solenoid. The resulting force is acting against the mechanical power control adjustment spring.

The mechanically adjusted basic power setting can be varied by means of different control current settings.

Increase in current = decrease in power

If the pilot current signal is adjusted by a load limiting control the power consumption of all actuators will be reduced to match the available power from the diesel engine.

A 12V (LE1) or 24V (LE2) supply is required for the control of the proportion solenoid.

LRD Power control with pressure cut-offThe pressure cut-off corresponds to a pressure control which adjusts the pump displacement back to Vg min, when the pres-sure setting is reached.

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

The pressure cut-off function is integrated into the pump cont-rol module and is preset to a specified value at the factory.

LRDS Power control with pressure cut-off and load sensing

The load sensing control is a flow control option that operates as a function of the load pressure to regulate the pump dis-placement to match the actuator flow requirement.

The flow depends here on the cross section of the external sensing orifice (1) fitted between the pump outlet and the actuator. The flow is independent of the load pressure below the power curve and the pressure cut-off setting and within the control range of the pump.

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

The load sensing control compares pressure before and after the sensing orifice and maintains the pressure drop across the orifice (differential pressure Δp) and with it the pump flow constant.

If the differential pressure Δp increases at the sensing orifice, the pump is swivelled back (towards Vg min), and, if the differen-tial pressure Δp decreases, the pump is swivelled out (towards Vg max) until the pressure drop across the sensing orifice in the valve is restored.

Δporifice = ppump – pactuator

The setting range for Δp is between 200 psi and 365 psi(14 bar and 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 orifice plugged) is slightly above the Δp setting.

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

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

LR... Power control with stroke limiterThe stroke limiter can be used to vary or limit the displacement of the pump continuously over the whole control range. The displacement is set in LRH with the pilot pressure pSt (maxi-mum 580 psi (40 bar)) applied to port Y or in LRU by the con-trol current applied to 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. below the hyperbolic power characteristic, the displacement is cont-rolled by the control current or pilot pressure. When exceeding the power characteristic with a set flow or load pressure, the power control overrides and reduces the displacement follo-wing the hyperbolic characteristic.

To permit operation of the pump displacement control from its starting position Vg max to Vg min, a minimum control pressure of 435 psi (30 bar) is required for the electric stroke limiter LRU1/2 and the hydraulic stroke limiter LRH2/6.

The required control pressure 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 even at low operating pressure, port G must be supplied with external control pressu-re of approx. 435 psi (30 bar).

NoteIf no external control pressure is connected at G, the shuttle valve must be removed.

LR – Power controlNote

The spring return feature in the controller is not a safety device

The spool valve inside the controller can get stuck in an undefined position by internal contamination (contamina-ted hydraulic fluid, abrasion or residual contamination from system components). As a result, the axial piston unit can no longer supply the flow specified by the operator.

Check whether your application requires that remedial mea-sures be taken on your machine in order to bring the driven consumer into a safe position (e.g. immediate stop).

DR – Pressure controlDRL Pressure control for parallel operationThe pressure control DRL is suitable for pressure control of se-veral axial piston pumps AA11VO in parallel operation pumping into a common pressure header.

The parallel pressure control has a pressure rise characteris-tic of approx. 220 psi (15 bar) from qv max to qv min. The pump regulates therefore to a pressure dependent swive angle. This results in stable control behavior, without the need of "staging" the individual pump compensators.

With the externally installed pressure relief valve (1) the nominal pressure setting of all pumps connected to the system is adjus-ted to the same value.


Each pump can be individually unloaded from the system by a separately 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.

HD – Hydraulic control, pilot-pressure relatedWith the pilot-pressure related control the pump displacement is adjusted in proportion to the pilot pressure applied to port Y.Maximum permissible pilot pressure pSt max = 580 psi (40 bar)

Control from Vg min to Vg max.

With increasing pilot pressure the pump swivels to a higher displacement.

Start of control (at Vg min), can be setfrom 60 to 145 psi (4 to 10 bar)


Starting position without control signal (pilot pressure):



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

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

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


Note





HD – Hydraulic control, pilot-pressure relatedHD.D Hydraulic control

with pressure cut-offThe pressure cut-off corresponds to a pressure control which adjusts the pump displacement back to Vg min when the pressu-re setting is reached.

This function overrides the HD control, i.e. the pilot-pressure related displacement control is functional below the pressure setting.

The pressure cut-off function is integrated into the pump cont-rol module and is preset to a specified value at the factory.

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

Control from Vg min to Vg max

With increasing control current the pump swivels to a higher displacement.

Starting position wthout control signal (control current):



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

The required control pressure is taken either from the load pressure, or from the externally applied control pressure at port G.To ensure the control even at low operating pressure < 435 psi (30 bar) the port G must be supplied with an external control pressure of approx. 435 psi (30 bar).


NoteInstall pump with EP control in the oil tank only when using mineral hydraulic oils and an oil temperature in the tank of maximum 180 °F (80 °C).

The following electronic control units and amplifiers are available for actuating the proportional solenoids (see also www.boschrexroth.com/mobilelektronik):

Installation notesGeneral

During commissioning and operation, the axial piston unit must be filled with hydraulic fluid and air bled. This is also to be obser-ved following a relatively long standstill as the system may empty via the hydraulic lines.

The case drain in the case interior must be directed to the tank via the highest tank port (T1, T2). The minimum suction pressure at port S must not fall below 12 psi (0.8 bar) absolute (without charge pump) or 9 psi (0.6 bar) (with charge pump).

In all operational conditions, the suction line and case drain line must flow into the tank below the minimum fluid level.

Installation position

See examples below. Additional installation positions are available upon request.

Below-tank installation (standard)Pump below the minimum fluid level of the tank.

Recommended installation positions: 1 and 2.

Above-tank installationPump above the minimum fluid level of the tank.

Observe the maximum permissible suction heighths max = 31.50 in (800 mm).

The version AA11VLO (with charge pump) is not designed for installation above the tank. Recommendation for installation position 7 (shaft up): A check valve in the case drain line (opening pressure 7.5 psi (0.5 bar)) can prevent the case interior from draining.For control options with pressure control, displacement limiters, HD and EP control, the minimum displacement setting must be Vg ≥ 5% Vg max.
