Axial Piston Variable Pump

AA10VG

Data sheet

Features

– Variable axial piston pump of swashplate design for hydrosta-

tic closed circuit transmission

– Flow is proportional to drive speed and displacement and is

infinitely variable

– Output flow increases with the swivel angle of the swash-

plate from 0 to its maximum value

– Flow direction changes smoothly when the swashplate is

moved through the neutral position

– A wide range of highly adaptable control devices is available

for different control and regulating functions

– The pump is equipped with two pressure relief valves on the

high pressure ports to protect the hydrostatic transmission

(pump and motor) from overload

– The pressure relief valves also function as boost valves

– The integrated boost pump acts as a feed and control oil

pump

– The maximum boost pressure is limited by a built-in boost

pressure relief valve

Technical Data

Hydraulic ﬂ uid

Before 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 applica-

tion conditions.

The variable pump AA10VG is unsuitable for operation with

HFA, HFB and HFC. If HFD or environmentally acceptable hy-

draulic fluids are being used, the limitations regarding technical

data and seals mentioned in RE 90221 and RE 90223 must

be observed.

When ordering, please indicate the hydraulic fluid used.

Operating viscosity range

For optimum efficiency and service life, select an operating vis-

cosity (at operating temperature) within the optimum range of

opt

= opt. operating viscosity 80...170 SUS (16...36 mm

/s)

depending on the circuit temperature (closed circuit).

Limits of viscosity range

The limiting values for viscosity are as follows:

min

= 42 SUS (5 mm

/s)

short term (t < 3 min)

at max. perm. temperature of t

max

= +240 °F (+115 °C)

max

= 7400 SUS (1600 mm

/s)

short term (t < 3 min)

at cold start

(p ≤ 435 psi / 30 bar, n ≤ 1000 rpm,

min

= -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

bearing area). The temperature in the bearing area is - depen-

ding on pressure and speed - up to 9 °F (5 K) higher than the

average case drain temperature.

Special measures are necessary in the temperature range from

-40 °F to -13 °F (-40 °C to -25 °C) (cold start phase), please

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

a closed circuit the circuit temperature.

The hydraulic fluid should be chosen so that the operating vis-

cosity in the operating temperature range is within the optimum

range (ν

opt

) - 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 °F (X °C) an ope-

rating temperature of 140 °F (60 °C) is set in the circuit. In

the optimum operating viscosity range (ν

opt

; shaded area) this

corresponds to the viscosity classes VG 46 or VG 68; to be

selected: VG 68.

Please note: The case drain temperature, which is affected by

pressure and speed, is always higher than the circuit tempera-

ture. 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 consult us.

Shaft seal ring

Permissible pressure loading

The service life of the shaft seal ring is affected by the speed

of the pump and the case drain pressure. It is recommended

that the average, continuous case drain pressure at opera-

ting temperature 45 psi (3 bar) absolute not be exceeded

(max. permissible case drain pressure 90 psi (6 bar) absolute

at reduced speed, see diagram). Short term (t < 0.1 s) pressu-

re spikes of up to 145 psi (10 bar) absolute are permitted. The

service life of the shaft seal ring decreases with an increase in

the frequency of pressure spikes.

The case pressure must be equal to or greater than the exter-

nal pressure on the shaft seal ring.

Temperature range

The FKM shaft seal ring is permissible for case temperatures of

-13 °F to +240 °F (-25 °C to +115 °C).

Note:

For application cases below -13 °F (-25 °C), an NBR shaft seal

ring is necessary (permissible temperature range: -40 °F to

+195 °F / -40 °C to +90 °C). Please state NBR shaft seal ring

in plain text when ordering. Please contact us.

Technical Data

Filtration

The finer the filtration, the higher the cleanliness level of the

hydraulic 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 cleanliness level of at least

20/18/15 according to ISO 4406.

Depending on the system and the application, for the AA10VG,

we recommend

Filter elements β

≥ 100

With a rising differential pressure at the filter elements, the

β-value must not deteriorate.

At very high hydraulic fluid temperatures (195 °F to max. 240 °F /

90 °C to max. 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.

For notes on filtration types, see page 38.

Pressure Cut-Off, D

The pressure cut-off corresponds to a pressure regulation

which, after reaching the set pressure, adjusts the displace-

ment of the pump to V

min

This valve prevents the operation of the high-pressure relief

valves when accelerating or decelerating.

Both the pressure peaks occurring when the swashplate is

swiveled rapidly and also the maximum pressure in the system

are safeguarded by the high-pressure relief valves.

The setting range of the pressure cut-off may be anywhere

within the entire operating pressure range. However, it must be

set 435 psi (30 bar) lower than the setting of the high-pressure

relief valves (see setting diagram, page 9).

Please state the setting value of the pressure cut-off in plain

text when ordering.

With the direct operated hydraulic control (DG), pump dis-

placement is controlled by a hydraulic pilot pressure applied

directly to the stroking piston through either the X

or X

port.

Flow direction is determined by which pilot port is pressurized

(please refer to the data table at the top of page 9; control

pressure column- X

; X

Pump displacement is infinitely variable and proportional to the

applied pilot pressure, but is also influenced by system pressu-

re and pump drive speed.

The P

port must be used as the pilot pressure source for the

selected control device, to enable the function of the built-in

pressure cut-off valve. Please refer to page 8 for a description

of the pressure cut-off function.

Application of the DG Control requires a review of the engine

and vehicle parameters to ensure that the pump is set up

correctly. All DG applications must be reviewed by a Rexroth

Application Engineer.

HD - Hydraulic Control, Pilot-Pressure Related

The flow output of the pump is infinitely varied between 0 and

100%, proportional to the difference in pilot pressure applied

to the two control ports (Y

and Y

The pilot signal, which originates from an external, remote sour-

ce, is pressure only. Flow is negligible as the pilot signal is only

acting on the spool of the control valve.

This spool then directs control oil into and out of the stroking

cylinder to adjust pump displacement as required.

A feedback lever, connected to the stroking piston, maintains

the pump flow for any given pilot signal.

If the pump is also equipped with a DA control valve (see pa-

ge 15), automotive operation is possible for travel drives.

Note

The spring return feature in the control unit is not a safety

The spool valve inside the control unit 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-

ween 0° and ±29° from the spring centered zero flow position.

A feedback lever, connected to the stroking piston, maintains

ween 0° and 29°.

If the pump is also equipped with a DA control valve (see pa-

The maximum required torque at the lever is 15 lb-in (170 Ncm).

To prevent damage to the HW control module a positive me-

chanical stop must be provided for the HW control linkage.

Note:

Spring centering enables the pump to move automatically into

neutral position (V

torque on the control lever of the HW control unit (regardless

of deflection angle).

Variation: Neutral position switch, L

The switch contact in the neutral position is closed when the

control lever on the HW control unit is in its neutral position.

The switch opens if the control lever is moved out of neutral in

either direction.

The neutral position switch provides a safety function for drive

units that require zero flow under certain operating conditions

(e.g. starting engine).

Bosch Rexroth Corp. 13/44

The DA control is an engine speed-dependent, or automotive,

type control system. The built-in DA regulating cartridge ge-

nerates a pilot pressure that is proportional to pump (engine)

drive speed. This pilot pressure is directed to the positioning

cylinder of the pump by a solenoid actuated 4/3 way direc-

tional valve. Pump displacement is infinitely variable in each

direction of flow, and is influenced by both pump drive speed

and discharge pressure. Flow direction (i.e. machine forward or

reverse) is controlled by energizing solenoid a or b.

Increasing pump drive speed generates a higher pilot pressure

from the DA cartridge, with a subsequent increase in pump

flow and/or pressure.

Dependent on the selected pump operating characteristics,

increasing system pressure (i.e. machine load) causes the

pump to swivel back towards a smaller displacement. Engine

overload (anti-stall) protection is achieved by the combination

of this pressure-related pump de-stroking, and the reduction of

pilot pressure as the engine speed drops.

Any additional power requirement, such as implement hy-

draulics, may result in further engine pull down. This causes a

further reduction in pilot pressure and therefore pump displace-

ment. Automatic power division and full utilization of available

power is thus achived for both the vehicle transmission and

the implement hydraulics, with priority given to the implement

hydraulics.

To provide controllable reduced vehicle speed operation when

high engine speeds are required for fast implement hydraulics,

various inching options are available.

The DA regulating cartridge can also be used in pumps with

conventional control devices, such as EP, HW or HD, to provi-

de an engine anti-stall function, or as a combination of automo-

tive and displacement control functions.

Application of the DA control is only appropriate on certain

types of vehicle drive systems, and requires a review of the

engine and vehicle parameters to ensure proper application

of the pump, and safe and efficient machine operation. All DA

applications must therefore be reviewed by a Rexroth Applica-

tion Engineer.

Combination pumps make it possible to have independent circuits without the need to fit splitter gearboxes.

When ordering combination pumps, the type designations of the 1st and 2nd pumps must be linked by a “+”.

Example of order:

AA10VG45HW1/10R-NTC60F045S + AA10VG45HW1/10R- NSC60F005S

A tandem pump combined of two equal sizes is permissible without additional supports where the dynamic acceleration does not exceed max.

0.022 lbs (= 322 ft/s

{10

(= 98.1 m/s

)}.

For combination pumps consisting of more than two pumps, the mounting flange must be rated for the permissible mass torque.

The mechanical stroke limiter is an additional function allowing

continuous reduction of the maximum displacement of the

pump, regardless of the control unit used.

The stroke of the stroke cylinder and hence the maximum

swivel angle of the pump are limited by means of two adjusting

screws.

General

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 pump case drain connection (i.e.-T

) must be directed to the tank via the highest case drain port. The minimum suction

pressure at port S must not fall below 12 psi (0.8 bar) abs. (cold start 7.5 psi / 0.5 bar absolute).

In all operating 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 installation

Pump above the min. ﬂ uid level of the tank

Observe the maximum permissible suction height h

max

31.5in

(800 mm)

Recommendation for installation position 8 (shaft upwards):

A check valve in the case drain line (opening pressure 7.5 psi /

0.5 bar) can prevent draining of the case interior.

Notice

RA 92750-A/06.09 AA10VG

Bosch Rexroth Corp. 43/44

– The AA10VG pump is designed to be used in closed circuits.

– Project planning, assembly and commissioning of the pump require the involvement of qualified personnel.

– The service line ports and function ports are only designed to accommodate hydraulic lines.

– During and shortly after operation, there is a risk of burns on the pump and especially on the solenoids. Take suitable safety

precautions, e.g. wear protective clothing

– There may be shifts in the characteristic depending on the operating state of the pump (operating pressure, fluid temperature).

– Tightening torques:

- The tightening torques specified in this data sheet are maximum values and must not be exceeded

(maximum values for screw thread).

Manufacturer´s instruction for the max. permissible tightening torques of the used fittings must be observed!

- For ISO 68 / DIN 13 fixing screws, we recommend checking the tightening torque individually according to

VDI 2230 Edition 2003.

– The data and information contained herein must be adhered to.
