directly to the stroking piston through either the X1 or X2 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- X1; X2).
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 Ps port must be used as the pilot pressure source for the T1 T2 X1 X2 S MA A
selected control device, to enable the function of the built-in
pressure cut-off valve. Please refer to page 8 for a description Version with DA control valve and pressure cut-off

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

flow and/or pressure. b X1 B to A MA
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-

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/s2) {10 g (= 98.1 m/s2)}.
For combination pumps consisting of more than two pumps, the mounting flange must be rated for the permissible mass torque.

Dimensions in inches and (millimeters).
The mechanical stroke limiter is an additional function allowing
continuous reduction of the maximum displacement of the M4
pump, regardless of the control unit used.
The stroke of the stroke cylinder and hence the maximum

screws.

Installation Situation for Coupling Assembly Before finalizing your design, please
request a binding installation drawing.
Dimensions in inches and (millimeters).
To ensure that rotating components (coupling hub) and fixed components (case, retaining ring) do not come into contact with
each other, the installation conditions described here must be observed. This depends on the size and the splined shaft.

Size 18 and 45 (with free turning):

– Please observe diameter of the free turning.

Size 63 (without free turning):

– The outer diameter of the coupling hub must be smaller than the inner diameter of the retaining ring d2 at the zone of the drive
shaft collar (measure x2 – x4).

Installation Notes
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.-T1/T2) 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) Above-tank installation

Pump below the minimum fluid level of the tank. Pump above the min. fluid level of the tank
Recommended installation positions: 1 and 2. Observe the maximum permissible suction height hmax = 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.
