VP1 Pump SAE
Design
Large angle - compact design
The pump design permits a large angle, 20°, between
piston and slipper shoe/swashplate, providing compact-
ness and small outer dimensions.
Long life
The VP1 is designed for trucks with hydraulic load sens-
ing systems. It is sturdy, yet simple, with few moving
parts. The result is a reliable pump with long service life.
The VP1 is a variable displacement pump for truck
applications. It can be close-coupled to a gearbox PTO
(power take-off) or to a coupling independent PTO (e.g.
an engine PTO).
An application that makes full use of all the features of
the VP1 is truck cranes with a load sensing system. The
complex systems of refuse collection vehicles and sew-
age trucks as well as various combinations of tippers,
cranes, snow ploughs, and salt/sand spreaders can also
be greatly simplified and optimised with the VP1 pump.
The VP1 provides the hydraulic system with the correct
amountofuidatpreciselytherightmoment,effectively
reducing energy consumption and heat generation. This
means a smoother and quieter hydraulic system with
much reduced impact on the environment.
The VP1 is highly efficient and extremely light. It is reli-
able, economical and easy to install.
The 3 sizes, VP1-095, -110 and -130 have small installa-
tion dimensions.
The VP1 is suitable for all load sensing systems,
regardless of make.

• Variabledisplacement
• Lownoiselevel
• Highpower-to-weightratio
• Compactandlight
• Highlyefcient
• Sturdydesign
• Withstandslowtemperatures
Retainer plate
The retainer plate (refer to the cut-away illustration
in next page) is of a heavy duty design which makes
the pump withstand high shaft speeds and fast speed
changes.(e. g. engine PTO).

VP1 in load sensing systems
When installed in a load sensing system, the VP1 sup-
pliesthecorrectamountofowrequiredbythevarious
work functions currently engaged.
This means that energy consumption and heat genera-
tion are minimised and much reduced in comparison
with a fi xed displacement pump used in the same sys-
tem.
Diagram1showstherequiredpower(owtimespres-
sure)inaconstantowsystemwithaxeddisplacement
pump.
Diagram 2 shows the sharply reduced power require-
ment in a load sensing system with a variable displace-
ment pump such as the VP1.
In both cases the pump pressure is slightly higher than
what is required by the heaviest load (’Load 2’) but the
VP1,becauseofthemuchsmallerowbeingdelivered,
needs only the power indicated by the shaded area
’Load power’.
Inaconstantowsystem,ontheotherhand,excess
uidisshuntedtotankandthecorrespondingpower,
’Wasted power’ (shown in diagram 1), is a heat loss.

LS load sensing control function
Refer to corresponding hydraulic schematic below.
A selected 'opening' of the directional control valve spool
correspondstoacertainowtotheworkfunction.This
ow,inturn,createsapressuredifferentialoverthe
spool and, consequently, also a ∆p between the pump
outlet and the LS port.
When the differential pressure decreases (e.g. the direc-
tional valve is ‘opened’ further) the ∆p also decreases
and the LS valve spool moves to the left. The pressure
to the setting pistons then decreases and the pump dis-
placement increases.
The increase in pump displacement stops when the ∆p
finally reaches the setting (e.g. 25 bar) and the forces
acting on the valve spool are equal.
If there is no LS signal pressure (e.g. when the direc-
tionalvalveisintheneutral,no-owposition)thepump
onlydeliverssufcientowtomaintainthestandbypres-
sure as determined by the ∆p setting.

NOTE:
- Make sure max torque and bending moment (due to
the weight of the pump) of the utilised PTO are not
exceeded. (The approx. center of gravity of the
various pump sizes are shown in the installation
drawings).
- Make sure max allowed output torque from the PTO
is not exceeded.

A suitable pump size for a truck application
can be selected as follows:
Operating conditions
As an example, a cargo crane specifies:
•Flow:60-80l/min(15.84-21.12gpm)
Pressure: 230 bar (3336 psi)
Diesel engine speed ≈ 800 rpm
Determine pump speed
As example a PTO with a Gear Ratio of
1:1.54.
The pump speed will be:
•800x1.54≈ 1200 rpm
Select a suitable pump size
Use diagram 1 and select a pump that will
provide 60 - 80 l/min at 1200 rpm.
Follow line 'a' (1200 rpm) until it
crosses line 'b' (70 l/min).
•F1-61isasuitablechoice
Required input torque
Make sure the PTO and the gear-box
tolerates the pump torque. Use diagram 2
to obtain the required pump torque.
Follow a line from 'c' (230 bar) until it
crosses the F1-61 line (the selected pump).
•Read220Nm(at'd')
NOTE: A rule-of-thumb is to select the
highest PTO ratio and the smallest pump
size that meets the crane specifica-
tion without exceeding the pump speed,
pressure, and power limitations.

speeds shown in table 2, right, should not be exceeded.
From table 1 (page 13), select the smallest line

example:
•At100l/min26.42 gpm, a 50 mm 2" suction line and
a 25 mm 1" pressure line is needed.
NOTE: Long inlet (suction) lines, low inlet pres-
sure (caused by e.g. a reservoir positioned below the
pump) and/or low temperatures may require larger line
dimensions.
Alternatively, the pump speed will have to be lowered
to
avoid pump cavitation (which may cause noise, deterio-
rating performance and pump damage).

ROTATION
Installation and start-up for F1
Drain line
Fixed displacement pumps don’t
need an external drain line as they
are internally drained.
When the pump is mounted in a
Engine-PTO we recommend a drain
line from the bypass valve directly to
oil tank.
Filtration
Filtration should follow ISO standard
4406, code 20/18/13.
To obtain the longest life of fixed dis-
placement pumps, we recommend
an oil cleanliness
of 10 µm (absolute).
Start-up
Make sure the entire hydraulic sys-
tem is clean before filling it with
arecommendedhydraulicuid.
In particular, make sure the pump is
filled (to at least 50%) as the internal
leakage does not provide sufficient
lubrication at start-up.
Fluids
The fixed displacement pumps data
shown in the specifications for each
pump in chapter 1 and 2 are valid
when operating on high quality, min-
eral based hydraulic oil.
Type HLP (according to DIN 51524)
hydraulic oil is suitable as well as
biologicallydegradeableuidslike
natural and synthetic esters and
polyalfaolefins.
Theutilisedhydraulicuidshall
meet one of the following Swedish
standards:
- SS 15 54 34
- SMR Hydraulic Oil Standard 1996-2.
Contact Parker Hannifin for further
information.
NOTE: - ATF (automatic transmis-
sionuid)andAPItype
CD engine oils may also
be useable.
- Seals are made of nitrile
rubber; make sure the
utiliseduidiscompatible
with this material.
Fluid temperature
Main circuit: Max 75 °C 167 °F.
NOTE: - The suction port should
always be above the
pressure port when the
pump is installed above
the reservoir oil level.
- During operation, the
pump must be filled with
oil to at least 50%.
Direction of rotation
The pictures above show direction of
owvs.shaftrotation.
The direction of rotation can be
changed (i. e. from right hand to left
hand) by turning the end cap.
Remove the four cap screws and turn
the end cap about half a turn while
making sure it stays in contact with
the barrel housing.
Re-fit the cap screws and torque to
59-74 lbf ft (80-100 Nm).
Installation
Make sure max torque and bending
moment (due to the weight of the
pump) of the utilised PTO are not
exceeded. (The approx. center of
gravity of the various pump sizes are
shown in the installation drawings).
NOTE: In order to obtain the longest
bearing life, the pump should
be installed according to
the
information shown on
page 20 "Pump bearing life".
Fluid viscosity
Recommended viscosity:
20 to 30 mm
2

Pump bearing life
Bearing life is dependent on how
the pump is installed on the PTO as
shown in the illustrations below.
A pump mounted according to fig.
1 gives the lowest bearing life; the
highest is obtained when installed
according to fig. 3.
Parker Hannifin will assist in deter-
mining bearing life in a particular
application.

Installation and start up
If any oil should drop 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 gearbox
caused by improper maintenance of the
hydraulic system.

• 10µm(absolute)incontaminatedenvironment
or at high pressures.
Filtration should meet ISO standard 4406:
code 20/18/13.
Drain line
The LS valve requires a separate drain line;
it should be routed directly to the reservoir
(refer to fig. 8).
Start-up
Make sure the entire hydraulic system is clean before
llingitwitharecommendeduid.
In addition, the VP1 pump must be purged to remove
any entrapped air in the pump housing; utilise the upper-
most purge port (fig. 8).
IMPORTANT
As shown in fig. 8, the pump inlet must always
be below the lowest reservoir oil level.

Direction of rotation
The basic VP1 pump is uni-directional; there is a left
hand and a right hand version (indicated by the arrow on
the side of the VP1 pump (fig. 4 and 5).
Consequently, the required direction of rotation must be
stated when ordering the pump.
Installation
The VP1 can be installed (close-coupled) directly on a
PTO.
Before start-up, the pump must be filled with hydraulic
uidandpurged.Utilisetheuppermostpurgeplug(refer
to the installation drawing on page 12, chapter 2).
Figure 6 (page 19) shows two ways of installing a gear
on the VP1 shaft. On a non-geared or a geared PTO
with support bearings, the pump shaft is usually installed
directly in the internally splined PTO output shaft.
Make sure max torque and bending moment (due to
the weight of the pump) of the utilised PTO are not
exceeded. (The approx. center of gravity of the various
pump sizes are shown in the installation drawings).
