Important installation
information
1. Make sure max input torque and max
bending moment of the PTO (including
the VP1 pump) are not exceeded.
Also, make sure the direction of rotation
of the VP1 pump correspond to the PTO,
and that pump and PTO specifications
are not exceeded in the application.
2. When VP1-045/075 is assembled to an
engine PTO make sure that the pump
isn’t overheated in the off-load mode. For
more information, see page 4, BPV-VP1
unloading valve.
3. Never use excessive force when install-
ing a gear, coupling or sleeve on the VP1
pump shaft.
4. The pump should be installed below the
lowest oil level in the reservoir (fig. 6, pg.
5);
if this is not possible, please contact
Parker Hannifin for further information.
5. A separate drain line must be installed
between the control drain port T and the
reservoir (refer to fig. 6, pg. 5); connect
the drain line directly to the oil cooler (if
the hydraulic system is so equipped).
6. A pressure relief valve is recommended
in the outlet (pressure) line from the
pump; it should be set 15–20 bar higher
than max pressure setting of the pump.
Example: The main pressure relief
valve located in the direc-
tional control valve.
7. Fill the pump with oil and bleed the pump
before start-up.
NOTE: - The suction fitting must be orde-
red separately (refer to pg. 7)
- VP1-045 / -075 installation on
a PTO:
please refer to page 3 for
information.
NOTE: Always run a function,
after adjusting the standby pres-
sure or the max pressure setting,
before you read the value.

The VP1 input shaft must not be subject to
external radial and/or axial forces (see
illustration to the right).
Installation examples:
a) A gear drive with a bearing supported
gear is acceptable (as shown in the illus-
tration below)
b) A gear mounted directly on the VP1 input
shaft is usually not acceptable
c) A belt drive pulley installed directly on
the VP1 input shaft is usually not allowed
Fig. 3. Usually, no external radial and/or
axial forces are allowed on the VP1 shaft
VP1 installation on a PTO /engine PTO
NOTE: If an installation according to
b) or c) above, is considered,
contact Parker Hannifin.

Installation Information Unloading Valve BPV for VP1
VP1 installation on an engine PTO
BPV-VP1 unloading valve
The BPV-VP1 unloading valve is utilized in
hydraulic systems where the pump is in
constant operation.
The valve protects the pump from being
overheated in the off-load mode by allow-
ing a small flow through the pump. When
load sensing valve function is engaged, the
bypass flow is cut off (as port ‘X’ is being
pressurized).
The valve will also de-air the suction line
and the pump body after a long standstill.
(The pump is assembled above the oil-
tank and during the standstill some of the oil
in the pump housing has been drained back
to the oil-tank)

Start-up procedure
- Make sure the entire hydraulic system is
as clean as possible before filling it with
a recommended fluid.
- The pump must be filled with fluid and
then purged before start-up (fig. 6).
Please note, that purging should only be
performed when the pump is connected
to the reservoir and the entire system is
filled with hydraulic fluid.
- Air in the VP1 (or in the rest of the
hydraulic system) can cause excessive
noise and damage pump performance.
- When starting up the system, activate
high flow/low pressure in order to purge
the hydraulic system properly.
- As previously pointed out, a separate
drain line is required between control
port T and the reservoir (fig. 6).
- Do not install a suction filter in the inlet
line.
Fluids
Suitable fluids: Mineral based, hydraulic flu-
ids type HLP (DIN 51524), ATF (automatic
transmission fluids) and API/CD motor oils.
Fluid temperature
Main circuit: Max 75 °C.
Viscosity
Recommended viscosity: 20 – 30 mm2/s
(cSt).
Operating viscosity limits:
- Min 10 mm2/s; max 400 mm2/s
- At start-up: max 1000 mm2/s.
Filtration
- 25 µm (absolute) in clean environment
and/or low pressures (<200 bar)
- 10 µm (absolute) in contaminated envi-
ronment and/or high pressures (200 bar
and above).
- Fluid cleanliness should follow ISO
standard 4406, code 20/18/13.
NOTE: Before start-up, open the uppermost
purge plug and purge the pump.
After purging, make sure the plug is
tightened but not to more than 30 Nm.

Tandem coupling VP1-045/075
The VP1 pump has a through-shaft which
means that an additional pump, such as a
fixed displacement F1, can be installed in
tandem with the VP1 by means of an adap-
tor kit (fig. 7).
NOTE:
The bending moment caused by the weight
of a tandem assembly normally exceeds
that allowed by the PTO.
To prevent damage, the auxiliary pump
should be supported by a bracket attached
to the gearbox; it must not be fastened to
the truck chassis.
Likewise, when the tandem assembly is
installed on a separate bracket and driven
by a cardan shaft, the auxiliary pump should
have a support attached to the pump bracket.
Fig. 7 Adaptor kit (P/N 379 7795) for tandem coupling.
IMPORTANT
Contact Parker Hannifin for additional
information when considering tandem
mounting a second VP1 pump.
Installation information tandem coupling
1. The pump must be filled with oil and then
purged before start-up.
2. Adaptor between the pumps shall be mounted
with the purge plug pointing upwards, fill and
purge the adaptor with oil.
3. Set the standby pressure on the controls
with a difference of 5 bar (Example 27 bar on
pump 1 and 32 bar on pump 2).

LS control adjustments
Signal pressure limiter
- The signal pressure relief valve is factory set at
330 bar (fig. 8).
- The LS pressure relief valve must not, under
any circumstance, be set higher than 380 bar
when the hydraulic system is being delivered to
a customer.
- Make sure max pressure not exceed 400 bar.
The pressure can easily be measured in the
gauge port on the pump housing.
Differential pressure setting
- The standby pressure, ∆p, is factory set at
25 bar but is adjustable to 35 bar.
- This 25 bar setting and the installed, standard
orifices usually provide an acceptable directiona l
valve characteristic as well as system stability.
For additional information, please contact
Parker Hannifin.

If any oil should come out of the indication-hole on the pump;
- Stop the system immediately.
- Determine the cause of leakage.
- Replace damaged parts.
- Make sure you have corrected the source of the problem, not only
the symptom.
Parker can not be held responsible for damage to PTO, engine and gear-
box caused by improper maintenance of the hydraulic system.
