Notes on the selection of hydraulic fl uid
In order to select the correct fl uid, it is necessary to know the
operating temperature in the tank (open circuit) in relation to
the ambient temperature.
The hydraulic fl uid should be selected so that within the ope-
rating temperature range, the viscosity lies within the optimum
range (
ν
opt
)
; see shaded section in the selection diagram. We
recommend, that the higher viscosity grade is selected in each
case.
Temperature range (see selection diagram)
t
min
= – 25° C
t
max
= + 90° C
Example: at an ambient temperature of X° C the operating
temperature in the tank is 60° C. In the optimum viscosity range
(ν
opt
; shaded area), this corresponds to grades VG 46 or VG 68;
select: VG 68.
Important: The case drain temperature is infl uenced by pres-
sure and speed and is always higher than the tank temperature.
However the max. temperature at any point in the system
may not
exceed 90° C.
Technical data
Hydraulic fl uid
For extensive information on the selection of hydraulic fl uids and
application conditions please consult our data sheets RE 90220
(mineral oils), RE 90221 (ecologically acceptable fl uids) and RE
90223 (HF-fl uids)
.
The variable pump A4VSO is suitable for operation on HF-fl uids.
(HFA, HFB, and HFC: EA4VSO or A4VSO....F
HFD: standard version A4VSO with FKM seals)
However, limitations to the technical data, according to
RE 90223 must be observed.
On certain selected HFC-fl uids, pump sizes 125...355, exe-
cuted in accordance to RE 92053 can be operated with the
same pressures and speeds as on mineral oil.
On operation with HFA and HFB-fl uids, limitations of the tech-
nical data must be observed according to RE 90223.
On operation with rolling oil please consult us.
When ordering, please state the fl uid to be used.
Operating viscosity range
Within the operating viscosity range between 16...100 mm
2
/s
the units can be operated without limitations of the technical
data.
In order to obtain optimum effi ciency and service life, we
recommend that the operating viscosity (at operating tempera-
ture) be selected in the range

Bearing fl ushing
For the following operating conditions bearing fl ushing is
required for a safe, continuous operation:
– Applications with special fl uids (non mineral oils) due to
limited lubricity and narrow operating temperature range
– Operation at critical conditions of temperature and viscosity
with mineral oil
Flushing is recommended with vertical mounting (drive shaft
facing upwards) in order to ensure lubrication of the front
bearing and shaft seal.
Flushing is carried out via port „U“, located in the front fl ange
area of the pump. The fl ushing fl uid fl ows through the front be-
aring and leaves the pump together with the case drain fl ow.
Depending on pump size, the following fl ushing fl ows are
recommended:
Size 40 71 125 180 250

Size 355 500 750 1000
recommended
fl ushing fl ow
q
Sp
L/min 15 20 30 40
These recommended fl ushing fl ows will cause a pressure drop
of approx. 2 bar (series 1) and 3 bar (series 3) between the
entrance to port„U“ and the pump case (including the pipe
fi ttings).
Notes regarding series 30
When using external bearing fl ushing the throttle screw at port
U must be turned in to the end stop.
Filtration of the fl uid (Axial piston unit)
The fi ner the fi ltration, the better the achieved cleanliness of
the fl uid and the longer the life of the axial piston pump.
To ensure a reliable functioning of the axial piston unit, a mini-
mum cleanliness class of
20/18/15 acc. to ISO 4406 is necessary.
Case drain pressure
The permissible case drain pressure (housing pressure) is
dependent on the drive speed (see diagram).

Summary of controls
Speed control DS1, secundary controlled (see RE 92056)
The speed control DS1 controls the secundary
unit (motor) in such a manner, that this motor
delivers suffi cient torque to maintain the required
output speed. When connected to a constant
pressure system, this torque is proportional to
motor displacement and thus also proportional to
the swivel angle

Electro hydraulic control system
DFE1
(see RE 92088)
The power, pressure and swivel angle control of the
variable pump A4VSO...DFE1 is accomplished by
means of an electrically controlled proportional val-
ve. A current signal to the proportional valve moves
the control piston and determines via an integrated
positional transducer the cradle‘s swivel angle and
thus the pump fl ow. When the electric drive motor
is switched off and the system is pressureless, the
bias spring in the control chamber will swivel the
pump to max. displacement (V
g max
).

Through drive
The axial piston unit A4VSO can be equipped with a through drive, as shown in the type code on page 4.
The through drive execution is designated by the code K/U 31...99.
We recommend, that no more than three pumps be coupled together.

Single pump with through drive
If no further pumps are factory-mounted the simple type code is suffi cient.
included in this case are:
on all through drives except K/U 99
shaft coupler, mounting screws, seal and if required an adapter fl ange
on K/U 99
with through drive shaft, without shaft coupler, without adapter fl ange; unit is closed with pressure tight cover.
Universal through drive
On pump sizes 125...355 all through drives are supplied as universal through drives „U“ .
These have the advantage, that they can be adapted later on.
Simply by exchanging the adapter fl ange and the shaft coupler it is possible to convert the through drive option.
The conversion sets must be ordered separately, see RE 95581.
Combination pumps
Independent circuits are available for the user when further pumps are built on.
1. If the combination consists of 2 Rexroth axial piston pumps, and if this must be factory mounted, the two individual type
codes must be joined by a „+“ .
Ordering example:
A4VSO 125 DR / 30 R – PPB13K33 + A4VSO 71 DR / 10 R – PZB13N00
2 If a gear or a radial piston pump must be factory mounted as the second pump please consult us.

Mounting position:
Optional. The pump case must be fi lled with fl uid during com-
missioning and remain full when operating.
In order to reduce the operating noise level, all connecting lines
(suction, pressure and case drain lines) must be de-coupled
from the tank, using fl exible elements.
The use of check valves in the case drain line must be avoided.
The case drain line must be returned directly to tank without a
reduction in cross section.
Exceptions maybe possible, please consult us fi rst.
1. Vertical installation (shaft end pointing upwards)
With a vertical installation, bearing fl ushing is recommended
to provide lubrication for the front bearing, see page 6.
The following installation conditions must be taken into
account:
1.1 Installation into the reservoir
a) When the minimum fl uid level is equal to or above the
pump mounting fl ange area: ports »R/L«, »T« and »S« open
(see fi g. 1).

Fig. 1
b) When the minimum fl uid level is below the mounting
fl ange area: ports»R/L«,»T« und possibly »S« must be piped
as shown in fi g. 2. Also observe the conditions as shown in
point 1.2.

1.2 Installation outside the reservoir
Before installation, fi ll the pump housing with the pump in a
horizontal position.
Pipe port »T« to tank, »R/L« plugged.
Filling in mounted condition: fi ll via »R« and bleed via»T«,
afterwards plug port»R«.
Conditions: A minimum pump inlet pressure (suction pres-
sure) of 0,8 bar abs. is necessary. Avoid mounting above
the reservoir in order to reduce the noise level.
2. Horizontal installation
The highest situated of the ports»T«,»K
1
«, »K
2
« or »R/L« must
be used for fi lling/bleeding and subsequently to connect the
case drain line.
2.1 Installation inside the reservoir
a) When the minimum fl uid level is equal to or lies above the
upper edge of the pump: case drain port and suction port
»S« open (see fi g. 3).

b) When the minimum fl uid level lies below the upper edge
of the pump: case drain port and possibly port »S« must be
piped, see fi g. 4. Observe conditions as shown in point 1.2.
Fill pump housing prior to commissioning.
2.2 Installation outside the reservoir
Fill the pump housing before commissioning.
a) Mounting above the reservoir see fi g. 4.
Observe conditions as shown in point 1.2.
b) Mounting below the reservoir
