Axial piston fixed pump | A17FO Series 10
Hydraulic fluid
Hydraulic fluid
The fixed pump A17FO is designed for operation with HLP
mineral oil according to DIN 51524.
Application instructions and requirements for hydraulic
fluids should be taken from the following data sheets
before the start of project planning:
90220: Hydraulic fluids based on mineral oils and
related hydrocarbons
90221: Environmentally acceptable hydraulic fluids
90222: Fire-resistant, water-free hydraulic fluids
(HFDR/HFDU)
The axial piston unit is not suitable for operation with
water-containing HF hydraulic fluid.
Notes on selection of hydraulic fluid
The hydraulic fluid should be selected such that the operat-
ing viscosity in the operating temperature range is within
the optimum range (ν
opt
see selection diagram).
Note
At no point of the component may the temperature be
higher than 115°C. The temperature difference specified in
the table is to be taken into account when determining the
viscosity in the bearing.
Please contact us if the above conditions cannot be met
due to extreme operating parameters.

Operating pressure range
Filtration of the hydraulic fluid
Finer filtration improves the cleanliness level of the hydraulic
fluid, which increases the service life of the axial piston unit.
A cleanliness level of at least 20/18/15 is to be maintained
according to ISO4406.
At very high hydraulic fluid temperatures (90°C to maximum
103°C, measured at air bleed port R), a cleanliness level of at
least 19/17/14 according to ISO4406 is necessary.

acceleration at start (lower than the maximum angular
acceleration) can be found in data sheet 90261.

Direction of rotation
Direction of rotation
The direction of rotation of the axial piston unit is defined
by means of a pressure connection screwed into the ser-
vice line port and can easily be changed.
By changing the pressure connection, the service line port
and the suction port are exchanged. As a result, the permis-
sible drive direction is changed. This is necessary when
mounting on a power take-off with counter-clockwise rota-
tion, for example. The procedure for conversion of the
pressure nipple can be found in the instruction manual
(91520-01-B, chapter 6.4.2 “Direction of rotation and
change of direction of rotation”).
Direction of rotation on delivery
On delivery, the pressure connection (1) is pre-assembled
in the right-hand service line port of the axial piston unit.
The permissible drive direction of the pump looking at the
drive shaft: counter-clockwise. The power take-off turns
clockwise.
Note
The pressure connection is pre-installed upon delivery and
must be tightened with the torque stipulated for the appro-
priate thread size prior to installation (see instruction
manual).

Notes on suction line
Keep as short and straight as possible, without sharp bend
Use a supporting ring for plastic hoses
Use two hose clamps to protect the suction hose against
air suction
Note pressure resistance of suction hose compared to
ambient pressure
Replacing seals
The O-rings used as seals to prevent air from entering the
suction line are to be replaced after every removal and new
installation in order to guarantee complete sealing.
Material number for O-rings:
R909083796: O-ring for suction stud G3/4
R909083802: O-ring for suction stud G1

Coupling flange
There are special, modified coupling flanges in 4-hole and
6-hole design for the cardan shaft drive.
The coupling flange is not included in the scope of delivery
and must be ordered separately.

Note
Assembly of the coupling flange is carried out by pull-
ing onto the drive shaft with the aid of the threaded
bore in the drive shaft end.
The coupling flange must be clamped on the drive
shaft using a socket-head screw. In addition, perma-
nent lubrication should be applied between the drive
shaft and the coupling flange.
The socket-head screw should be secured in a suitable
manner (e.g. gluing with Loctite 276) and tightened
with a tightening torque of 130Nm.
Sudden axial impact upon the drive shaft will lead to
rotary group damage and therefore must be avoided.

Axial piston fixed pump | A17FO Series 10
Installation instructions
Installation instructions
General
During commissioning and operation, the axial piston unit
must be filled with hydraulic fluid and air bled. This must
also be observed following a long standstill as the axial
piston unit can empty via the hydraulic lines.
The pump housing is internally connected to the suction
chamber. A separate drain line from the housing to the
reservoir is not needed.
To achieve favorable noise values, decouple all connecting
lines using elastic elements and avoid above-reservoir
installation.
In all operating conditions, the suction line must flow into the
reservoir below the minimum fluid level. The permissible
suction height h
S
results from the overall loss of pressure.
However, it must not be higher than h
Smax
=800 mm. The
minimum suction pressure at port S must also not fall below
0.8bar absolute during operation and during cold start.
Installation position
See the following examples 1 to 4.
Further installation positions are available upon request.
Recommended installation position: 1 and 2.
Below-reservoir installation (standard)
Below-reservoir installation means that the axial piston unit
is installed outside of the reservoir below the minimum
fluid level.

Project planning notes
Project planning notes
The A17FO pump is designed to be used in open circuits.
The project planning, installation and commissioning of
the axial piston unit requires the involvement of quali-
fied personnel.
Before using the axial piston unit, please read the corre-
sponding instruction manual completely and thoroughly. If
necessary, these can be requested from Bosch Rexroth.
Before finalizing your design, please request a binding
installation drawing.
The specified data and notes must be observed.
Depending on the operating conditions of the axial
piston unit (operating pressure, fluid temperature), the
characteristic may shift.
Preservation: Our axial piston units are supplied as
standard with protection to preserve for a maximum of
12 months. If longer preservative protection is required
(maximum 24 months), please specify this in plain text
when placing your order. The preservation periods apply
under optimal storage conditions, details of which can
be found in the data sheet 90312 or the instruction
manual.
Not all variants of the product are approved for use in
safety functions according to ISO13849. Please consult
the responsible contact person at Bosch Rexroth if you
require reliability parameters (e.g. MTTF
d
) for functional
safety.
Be sure to add a pressure relief valve to the hydraulic
system.
Please note the details regarding the tightening torques
of port threads and other threaded joints.
Working ports:
The ports and fastening threads are designed for the
specified maximum pressure. The machine or system
manufacturer must ensure that the connecting ele-
ments and lines correspond to the specified applica-
tion conditions (pressure, flow, hydraulic fluid, tem-
perature) with the necessary safety factors.
The service line ports and function ports can only be
used to accommodate hydraulic lines.
Safety instructions
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).
