The following must be taken into account during project planning:
Excessive current levels (I > 1200 mA with 12 V or I > 600 mA with 24 V) to the ER solenoid can result in undesired increase
of pressure which can lead to pump or system damage:
- Use Imax current limiter solenoids.
- A sandwich plate pressure reducing valve can be used to protect the pump in the event of overflow.
An accessory kit with sandwich plate pressure reducing valve can be ordered from Rexroth under part number R902490825.

Technical data
Hydraulic fluid
Notes on the choice of hydraulic fluid
Before starting project planning, please refer to our data
sheets RE 90220 (mineral oil), RE 90221 (environmentally
acceptable hydraulic fluids) and RE 90222 (HFD hydraulic
fluids) for detailed information regarding the choice of hydraulic
fluid and application conditions.
In order to select the correct hydraulic fluid, it is necessary to
know the operating temperature in the reservoir (open circuit)
in relation to the ambient temperature.
If environmentally acceptable hydraulic fluids are being used,
the limitations regarding technical data and other seals must
be observed. Please contact us.
Operating viscosity range
For optimum efficiency and service life we recommend that the
operating viscosity (at operating temperature) be selected in
the range
nopt = opt. operating viscosity 80 - 170 SUS (16 ... 36 mm /s)
2
referred to reservoir temperature (open circuit).
Limits of viscosity range
For critical operating conditions the following values apply:
nmin =
60 SUS (10 mm2/s)
short-term (t ≤ 1 min)
at max perm. case drain temperature of 239 °F
(115 °C).
7500 SUS (1600 mm2/s)
short-term (t ≤ 1 min)
on cold start
(p ≤ 435 psi (30 bar), n ≤ 1000 rpm, tmin -13 °F
(-25 °C))
Depending on the installation situation, special measures are
necessary at temperatures between -40 °F (-40°C) and -13 °F
(-25°C). Please contact us.
For detailed information on operation with low temperatures
see data sheet RE 90300-03-B.

Example: at an ambient temperature of X °F (°C) the operating
temperature is 140 °F (60 °C). In the optimum operating viscosity range (nopt; shaded area) this corresponds to viscosity
grades VG 46 resp. VG 68; VG 68 should be selected.
Important:
The case drain temperature is influenced by pressure and input
speed and is always higher than the reservoir temperature.
However, at no point in the component may the temperature
exceed 239 °F (115 °C). The temperature difference specified
on the left is to be taken into account when determining the
viscosity in the bearing.
If the above conditions cannot be met, due to extreme operating parameters please contact us.
Please also ensure that the max. case drain temperature
of 239 °F (115 °C) is not exceeded in localized areas (for
instance, in the bearing area). The fluid temperature in the
bearing area is
approx. 7 °F (5 K) higher than the average case drain temperature.
nmax = The hydraulic fluid should be selected so that within the operating temperature range, the viscosity lies within the optimum
range (nopt), see shaded section of the selection diagram. We
recommend to select the higher viscosity grade in each case.

Filtration of the hydraulic fluid
The finer the filtration the better the cleanliness level of the hydraulic fluid and the longer the service life of the axial piston unit.
In order to guarantee the functional reliability of the axial piston
unit it is necessary to carry out a gravimetric evaluation of the
hydraulic fluid to determine the particle contamination and the
cleanliness level according to ISO 4406. A cleanliness level of
at least 20/18/15 must be maintained.
At very high hydraulic fluid temperatures (195 °F (90 °C) to maximum 239 °F (115 °C)), a cleanliness level of at least 19/17/14
according to ISO 4406 is necessary.
If the above cleanliness levels cannot be maintained, please
contact us.

1) The
values are applicable:
- for an absolute pressure pabs = 15 psi (1 bar) at suction port S
- within the optimum viscosity range from nopt = 80 to 170 SUS (16 to 36 mm2/s)
- for mineral-oil based hydraulic fluid.
2)
The scope of application lies between the minimum necessary and the maximum permissible drive speeds.
Valid for external excitation (e.g. diesel engine 2- to 8-fold rotary frequency, cardan shaft 2-fold rotary frequency).
The limiting value is only valid for a single pump.
The loading capacity of the connecting parts must be taken into account.
Note
Exceeding the maximum or falling below the minimum permissible values can lead to a loss of function, a reduction in operational
service life or total destruction of the axial piston unit. We recommend to check the loading through tests or calculation / simulation and comparison with the permissible values.

service life or total destruction of the axial piston unit. We recommend to check the loading through tests or calculation / simulation and comparison with the permissible values.
Sizes 45, 71, 100 and 140 are optionally available in high-speed version.
External dimensions are not affected by this option.

DG – Two-point control, directly operated
The variable pump can be set to a minimum swivel angle
by connecting an external control pressure to port X.

This will supply control fluid directly to the stroke piston;
a minimum control pressure of pst ≥ 725 psi (50 bar) is required.
X
The variable pump can only be switched between Vg max or Vg min.

Please note, that the required control pressure at port X is
directly dependent on the actual operating pressure pB in
port B. (See control pressure characteristic).

DR – Pressure control
The pressure control limits the maximum pressure at the pump
output within the pump control range. The variable pump only
supplies as much hydraulic fluid as is required by the consu­
mers. If the operating pressure exceeds the pressure setpoint
set at the integrated pressure valve, the pump will adjust
towards a smaller displacement and the control deviation will
be reduced. The pressure can be set steplessly at the control
valve.

DRG – Pressure control, remotely operated
The DR-control valve (see page 11) is overriding this DRGremote setting of max. outlet pressure.
Circuit diagram, sizes 18 to 100
Not included in the delivery contents
A pressure relief valve can be externally piped to port X for
remote setting of pressure below the setting of the DR control
valve spool. This relief valve is not included in the delivery
contents of the DRG control.
X
The differential pressure at the DRG control valve is set as
standard to 290 psi (20 bar). This results in a pilot oil flow to
the relief valve of approx. 0.4 gpm (1.5 l/min) at port X. If another setting is required (range from 145-320 psi (10-22 bar))
please state in clear text.

As a separate pressure relief valve we can recommend:
B
DBDH 6 (hydraulic) to RE 25402 or
DBETR-SO 381 with orifice dia 0.03 inch (Ø 0.8 mm) in P
(electric) to RE 29166.

Execution of the pressure control like DR(G), see page 11 (12).
Execution of the flow control like DFR, DFR1, see page 13.
In order to achieve a constant drive torque with varying operating pressures, the swivel angle and with it the output flow from
the axial piston pump is varied so that the product of flow and
pressure remains constant.
Control data
For pressure control DR data, see page 11.
For flow control FR data, see page 13.
Flow control is possible below the power control curve.

ED – Electro-hydraulic pressure control
Influence of pressure setting on standby level
The ED valve is set to a certain pressure by a specified,
variable solenoid current.
psi (bar)
435 (30)
If there is a change at the consumer (load pressure),
the position of the control piston changes.
This causes an increase or decrease in the pump swivel angle
(flow) in order to maintain the electrically set pressure level.
The pump thus only delivers as much hydraulic fluid as the
consumers can take. The desired pressure level can be set
steplessly by varying the solenoid current.

When the solenoid current signal drops towards a zero value,
the maximum output pressure is limited to pmax by an adjustable
hydraulic pressure cut-off (secure fail safe function in case of a
loss of power e.g. for use as fan drives).
The response time characteristic of the ED-control was
optimized for the use as a fan drive system.

Combination pumps A10VO + A10VO
Before finalizing your design request a certified
installation drawing.
Dimensions in inches and (mm).
When using combination pumps it is possible to have multiple, mutually independent circuits without the need for a splitter
gearbox.
When ordering combination pumps the model codes for the first and the second pump must be joined by a "+".
Order example:
A10VSO100DFR1/31R-VSB12K04+
A10VSO45DFR/31R-VSA12N00
If no further pumps are to be factory-mounted, the simple type code is sufficient.
It is permissible to use a combination of two single pumps of the same size (tandem pump), considering a dynamic mass acceleration force of maximum 10 g (= 98.1 m/s2) without an additional support bracket.
Each through drive is plugged with a non-pressure-resistant cover. Before commissioning the units, they must therefore be
equipped with a pressure-resistant cover.
Through drives can also be ordered with pressure-resistant covers. Please specify in clear text.
For combination pumps comprising more than two pumps, the mounting flange must be calculated for the permissible moment of
inertia.

Installation instructions
General
Below-reservoir installation (standard)
The axial piston unit must be filled with hydraulic fluid and air
bled during commissioning and operation. This must also be
observed following a longer standstill as the axial piston unit
empty via the hydraulic lines.
Below-reservoir installation means the axial piston unit is installed outside of the reservoir below the minimum fluid level.
1
Particularly with the "drive shaft up/down" installation position,
filling and air bleeding must be carried out completely as there
is, for example, a danger of dry running.
2

The case drain fluid in the motor housing must be directed to
the reservoir via the highest case drain port (L1, L2, L3).
SB
ht min

For combinations of multiple units, make sure that the respective case pressure in each unit is not exceeded. In the event of
pressure differences at the case drain ports of the units, the
shared case drain line must be changed so that the minimum
permissible case pressure of all connected units is not exceeded in any situation. If this is not possible, separate case drain
lines must be laid if necessary.

Installation instructions
Above-reservoir installation
Inside-reservoir installation
Above-reservoir installation means the axial piston unit is
installed above the minimum fluid level of the reservoir.
To prevent the axial piston unit from draining, a height
difference hES min of at least 0.98 in (25 mm) at port L 1 is
required in installation position 6.
Inside-reservoir installation is when the axial piston unit is
installed in the reservoir below the minimum fluid level.
The axial piston unit is completely below the hydraulic fluid.
Observe the maximum permissible suction height
hS max = 31.50 in (800 mm).
A check valve in the case drain line is only permissible in
individual cases. Consult us for approval.

Axial piston units with electrical components (e.g. electric control, sensors) may not be installed in a reservoir below
the fluid level.

General instructions
–– The A10VO / A10VSO pump is designed to be used in open circuit.
–– Project planning, installation and commissioning of the axial piston unit require the involvement of qualified personnel.
–– Before operating the axial piston unit, please read the appropriate instruction manual thoroughly and completely. If necessary, request these
from Bosch Rexroth.
–– During and shortly after operation, there is a risk of burns on the axial piston unit and especially on the solenoids.
Take appropriate safety measures (e.g. by wearing protective clothing).
–– Depending on the operating conditions of the axial piston unit (operating pressure, fluid temperature), the characteristics may shift.
–– Service line ports:
-- The ports and fastening threads are designed for the specified maximum pressure. The machine or system manufacturer must ensure that
the connecting elements and lines correspond to the specified application conditions (pressure, flow, hydraulic fluid, temperature) with the
necessary safety factors.
-- The service line ports and function ports are only designed to accommodate hydraulic lines.
–– Pressure cut-off and pressure control do not provide security against pressure overload. A separate pressure relief valve is to
be provided in the hydraulic system.
–– The data and notes contained herein must be adhered to.
–– The product is not approved as a component for the safety concept of a general machine according to ISO 13849.
–– The following tightening torques apply:

Observe the manufacturer‘s instruction regarding the tightening torques of the used fittings.
-- Mounting bolts:
For mounting bolts with metric ISO thread according to DIN 13 or thread according to ASME B1.1, we recommend checking the tightening
torque individually according to VDI 2230.
-- Female threads in axial piston unit:
The maximum permissible tightening torques MG max are maximum values for the female threads and must not be exceeded. For values, see the
following table.
-- Threaded plugs:
For the metal threaded plugs supplied with the axial piston unit, the required tightening torques of the threaded plugs
