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 VP1-095, -110 and -130 is as-
sembled 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.

NOTE: - The suction fitting must be orde-

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 al-
lowed
Fig. 3. Usually, no external radial and/or
axial forces are allowed on the VP1 shaft

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 environ-
ment and/or high pressures (200 bar and
above).
- Fluid cleanliness should follow ISO stand-
ard 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.

System pressure limiter
- The system (high) pressure relief valve is
factory set at 350 bar.
- Although it can be set higher, the system
pressure relief valve must not, under any
circumstance, be set higher than 400 bar
when the hydraulic system is being deliv-
ered to the final customer.
- Make sure ‘max peak pressure 420 bar’,
as measured in gauge port M on pump
(see fig. 3), is not exceeded.
Standby pressure
- The standby pressure, ∆p, is factory set at
25 bar but is adjustable between 15 and
40 bar.
- The 25 bar setting and the standard
orifices usually provide an acceptable
directional valve characteristic as well as
system stability.
- For additional information, please contact
Parker Hannifin.
Adjustments (refer to fig. 7 below)
1. System (high) pressure adjustment
screw; factory set at 350 bar (1 turn
approx. 140 bar)1)
2. Counter nut for adjustment screw 1
3. Bushing; basic valve setting, factory set;
DO NOT TOUCH!
Note: Before you read the measured
value, always activate and run a func-
tion after you have made the adjust-
ment of settings.
Adjust standby pressure first and then
the system pressure.
4. Standby pressure adjustment bushing;
factory set at 25 bar (1 turn approx.
17 bar)1)
5. Counter nut for bushing 4.
1) Before attempting to change a setting,
the corresponding counter nut must be
opened; it should be re-tightened after
the adjustment.

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.
