Variable vane pump, direct controlled | PV7...A Series 1X / 2X
Functional description

Functional description
Hydraulic pumps, type PV7...A are direct controlled vane
pumps with variable displacement.
The basically comprise of the housing (1), cover (2), rotor
(3), vanes (4), stator ring (5), pressure spring (6), adjust-
ment screw (7) and control plate (8).
For limiting the maximum flow, the pump is fitted with an
adjustment screw (9).
The driven rotor (3) rotates within the stator ring (5). The
vanes (4) which are guided in the rotor (3) are pressed
against the inner running surface of the stator ring (5) by
centrifugal force.
Suction and displacement process
The chambers (10) which are required for the transport of
the hydraulic fluid are formed by the vanes (4), the rotor
(3), the stator ring (5), the control plate (8) and the cover
plate (2).
The chamber volume increases as the rotor (3) rotates and
the chambers are filled with hydraulic fluid via the suction
channel (S). When the largest chamber volume is reached,
the chambers (10) are separated from the suction side.
As the rotor (3) continues to rotate the connection to the
pressure side is opened, the chambers decrease in size and
force the hydraulic fluid into the system via the pressure
port (P).
Pressure control
The stator ring (5) is held in its initial excentric position by
spring (6). The maximum operating pressure required in
the system is set at the adjustment screw (7) via the spring
(6).
The pressure which builds up due to the work resistance
acts on the pressure side of the inner running surface of
the stator ring (5), against the force of the spring (6).
When the relevant pressure is reached, which is determined
by the set spring force, the stator ring (5) is moved out of
its excentric position in the direction of the zero position.
The flow adjusts itself to the value which is being
demanded at that time. When the maximum pressure,
which has been set at the spring (6), has been reached
then the pump regulates the flow back to virtually zero. The
operating pressure is maintained and only the case drain is
replaced. Losses and heating of the hydraulic fluid is
thereby minimized.

tained in the hydraulic systems. Effective filtration prevents faults
from occurring and at the same time increases the component
service life.

Project planning notes
Project planning notes
When using vane pumps we recommend that the following
instructions are particularly taken into account.
Project planning, installation and commissioning of the
vane pumps require the involvement of qualified personnel.
Technical data
All the technical data are dependent on manufacturing
tolerances and are valid with certain operating conditions.
Please therefore take into account that minor variations are
possible and technical data can be affected by differing
conditions (e.g. viscosity).
Characteristics for flow and absorbed power
Please take into account when dimensioning the engine the
maximum possible application data.
Noise
The values for sound pressure levels as shown on pages
6 to 9 were measured according to DIN45635 part
26. That means, only the noise emission of the pump is
depicted. Ambient influences (such as place of installation,
piping, etc.) are not taken into consideration. The values
only refer to one pump.
Note
The power unit design and the influences at the unit‘s
final place of installation, result in general in the fact that
the sound pressure levels lie 5 to 10 dB(A) higher than
that of the pump alone.
Case drain
On page 4 the average external case drain of the pump is
stated. Consider, that these values are only meant to be
project planning for determining cooler and pipeline sizes.
The zero stroke power is the relevant factor for the dimen-
sioning of the reservoir (see page 6 to 9). Restric-
tions in pipeline cross sections but also the use of
a case drain cooler can cause impermissible high pressure
spikes in the case drain line.
Pressure safeguarding
Pressure controller are not backups against pressure
overload. A separate pressure-relief valve is to be provided
in the hydraulic system.

Installation instructions
Fluid reservoir
▶ Match the usable reservoir volume to the operating
conditions.
▶ The permissible fluid temperature may not be exceeded,
if required, provide a cooler!
Lines and ports
▶ Remove protective plugs from the pump.
▶ We recommend the use of seamless precision steel
pipes according to DIN 2391 and removable pipe
connections.
▶ Select the pipe inside diameters according to the port
size.
▶ Throughly clean pipelines and fittings prior to installing.

Case drain
line
Suction line
▶ The case drain line to install in such a manner, that the
pump cannot drain empty!
▶ Under no circumstances may case drain and return fluid
be directly taken up in the pump suction port!
Filter
If possible, use return-line filters or pressure-line filters.
(Suction filter only in conjunction with low pressure switch/
clogging indicator)
Hydraulic fluid
▶ Please observe our specifications according to data
sheet 90220.
▶ We recommend brand name hydraulic fluids.
▶ Do not mix hydraulic fluids of different types since this
can result in decomposition and deterioration of the
lubricating quality.
▶ The hydraulic fluid must be replaced at regular intervals
relevant to the operating conditions. In connection with
this, the oil reservoir must also be cleaned of residues.
Drive
Electric motor + pump support + coupling + pump
▶ No radial or axial forces permissible on the pump drive
shaft!
▶ Motor and pump must be exactly aligned!
▶ Use torsionally flexible couplings.

Commissioning instructions
Commissioning instructions
Air bleeding
▶ All of the PV7...A type vane pumps are self-priming.
▶ Before initial commissioning , the pump must be air-bled
to protect it against damage.
▶ During the initial commissioning, we recommend to fill
the housing through the case drain line. Take into
account the filter grade! This increases operating safety
and prevents wear in the case of unfavorable installation
conditions.
▶ If the pump flow is not bubble-free after approx.
20 seconds, the system has to be rechecked. After the
operating values have been reached, check the pipe
connections for leakage and check the operating tem-
perature.
Commissioning
▶ Check whether the system is thoroughly and properly
installed.
▶ Take into account the motor and pump direction of
rotation arrows.
▶ Start the pump without load and let the flow run with-
out pressure for a few seconds in order to provide suf-
ficient lubrication.
▶ On no account let the pump run without hydraulic fluid!
Note
▶ Adjustment, maintenance and repair of the pump
may only be carried out by authorized, trained and
instructed personnel!
▶ Use only original Rexroth spare parts!
▶ The pump may only be operated within the permissible
data.
▶ The pump may only be operated when in perfect
condition!
▶ When carrying out any work on the pump (e.g. mount-
ing and removal) switch the system to zero pressure
and isolate from the mains supply!
