The VPPL are variable displacement axial-piston pumps
with variable swash plate, suitable for applications with
open circuits and intermediate pressures.
They are available in seven nominal sizes, with
displacements of 8, 16, 22, 36, 46, 70 and 100 cm
3
/rev.
The pump flow rate is proportional to the rotation speed
and to the angle of the swash plate, which can be
continuously modulated. The maximum and minimum
angle can be limited mechanically via suitable regulating
screws.
They are usually supplied with a SAE J744 2-hole flange
and a SAE J744 cylindrical with key shaft.
They are available with four different types of regulating
control, each according to the application needs.

2 - HYDRAULIC FLUID
2.1 - Fluid type
Use mineral oil-based hydraulic fluids HL or HM type, according to ISO 6743-4. With these fluids use NBR seals. Using fluids at temperatures
higher than 70 °C causes a faster degradation of the fluid and of the seals characteristics. The fluid must be preserved in its physical and
chemical characteristics.
The operating fluid viscosity must be within the following range:
minimum viscosity 10 cSt referred to a maximum temperature of 90 °C for the drainage fluid
optimum viscosity 20 / 50 cSt referred to the operating temperature of the fluid in the tank
maximum viscosity 1000 cSt limited only to the cold start-up of the pump, which has to be carried out with the plant at
minimum pressure.
When selecting the fluid type, be sure that the true viscosity is within the range specified above at the operating temperature.
2.2 - Fluid viscosity
2.3 - Degree of fluid contamination
The maximum degree of fluid contamination must be according to ISO 4406:1999 class 20/18/15; therefore the use of a delivery or return filter
with β
20
≥75 is suggested.
A degree of maximum fluid contamination according to ISO 4406:1999 class 20/16/13 is recommended for optimum endurance of the pump.
Hence, the use of a filter with β
10
≥100 is recommended.
For the installation of filters on the suction line, see paragraph 10. The suction filter must be equipped with a by-pass valve and, if possible, with
a clogging indicator and should be oversized to avoid cavitation problems.

The PC* pressure regulator keeps the pressure at a constant set level in
the circuit, thus adjusting automatically the pump flow rate according to the
real need of the system.
The desired pressure can be set by manually adjusting the P regulation
valve. The clockwise rotation of the adjustment bolt makes the pressure
increase.
FEATURES OF THE PC REGULATOR:
- pressure adjustment range:
PC5 = 30 ÷ 210 bar (for VPPL 008, 016, 022, 036 and 046)
pressure increase/adjustment screw round: 69 bar
PC6 = 30 ÷ 280 bar (for VPPL 070 and 100)
pressure increase/adjustment screw round: 78 bar
4 - REGULATORS
4.1 - Pressure regulator: PC*
4.2 - Remote-controlled pressure regulator: PCR
FEATURES OF THE REGULATOR:
- remote-adjustment pressure = 20 ÷ 210 bar
- flow rate available on the X port
for the remote-control = about 1,5 l/min (approx.)
4.3 - Pressure and flow rate regulator: PQC
This regulator, in addition to the pressure adjustment (as for the
PC* model), allows the pump flow rate control, according to the ∆p
pressure drop measured on either side of a throttle valve installed
on the user line.
Note: The connection pipe between the X port and the flow line
downstream the restrictor (or valve) must always be made
(customer charge).
FEATURES OF THE PQC REGULATOR:
- pressure adjustment range:
11 ÷ 190 bar (for VPPL 008, 016, 022, 036 and 046)
13 ÷ 230 bar (for VPPL 070 and 100)
- pressure increase/adjustment screw round: 78 bar
- differential pressure adjustment range = 15
÷ 28 bar
- minimum delivery pressure = 15 bar
4.2.1 - Remote-controlled pressure regulator: PCR
for VPPL 008, 016, 022, 036 e 046
4.2.2 - Remote-controlled pressure regulator: PCR
for VPPL 070 e 100
The PCR regulator allows a remote-control of the device via a remote control connected to the X port (typical application for submerged
pumps).
In case a pressure regulating valve is used for the remote-control, it is suggested to use a direct operated valve with a size suitable to 1,5 l/min
pilot flow rate.
Note: The maximum length of the connection between the valve and X port of the pump must not be longer than 2 m.
FEATURES OF THE REGULATOR:
It also limits the line maximum pressure.
- pressure regulating range 30
÷ 280 bar
- pressure increase/adjustment screw round: 78 bar
- remote-regulated pressure range = 20 ÷ 280 bar
- flow rate available on the X port for the remote-control = about 1,5 l/min

The PCX* regulator, mated to a suitable two-position solenoid valve,
allows the electrical switching of the pump displacement in null
condition and with minimum delivery pressure.
This function is useful for the pump unloading at the start-up or to
operate at minimum pressure in the system during the machine cycle
pause, with considerable energy saving.
The pressure switching is made by means of a solenoid valve (to be
ordered separately) installed on the pump regulator directly.
PCX* FEATURES (electrical unloading):
- solenoid switching valve (1) = DS3-SA2 type
(to be ordered separately - see cat. 41 150)
- solenoid valve OFF = pump at null displacement and delivery
pressure = 20 bar
- solenoid valve ON = maximum displacement and delivery
pressure set on regulator.
- pressure regulating range:
20 ÷ 210 bar for VPPL-008, 016, 022, 036 and 046
20 ÷ 280 bar for VPPL-070 and 100
- pressure increase/adjustment screw round = 78 bar

The PCX regulator mated with a proportional pressure relief valve,
allows a continuous control and modulation of the system pressure.
The proportional pressure relief valve (to be ordered separately) is
installed on the pump regulator directly.
PCX* FEATURES (proportional pressure regulation):

PCX5 = 20 ÷ 210 bar for VPPL-008, 016, 022, 036, 046.
PCX6 = 20 ÷ 280 bar for VPPL-070 and 100
- pressure increase/adjustment screw round = 78 bar

11 - CONNECTION FLANGES
10 - INSTALLATION
- The VPPL pumps can be installed both in a horizontal and vertical position, with the shaft in an upward position.
Note: the drain port has to be oriented so that the oil level inside the pump body is never lower than 3/4 of its volume.
- In the case of installation above the oil level, check that the minimal inlet pressure is not lower than -0.2 bars (relative). If a low noise emission
level is required, the installation inside the tank is suggested.
In case of an installation inside the tank, with an oil level which does not grant complete pump submersion, it is suggested to adjust thee drain
tube so that the pump higher bearing can be always lubricated.
- Before starting, the pump body has to be filled with the fluid.
- Check the pump direction of rotation.
- It is necessary to vent the air from the delivery connection before operating it the first time. If the air venting should be difficult, the use of a
venting valve is recommended.
The pump start up should occur with the plant at minimum pressure, especially with low temperatures.
- The suction tube has to be suitably sized so that the suction pressure is never lower than -0.2 bar (relative). Bends or restrictions or an
excessive tube length could further decrease the value of the suction pressure with a following increase in the noise emissions and a
decrease in the pump lifetime.
- The drainage tube has to be sized so that the pressure inside the pump body is always lower than 0.5 bars (relative), even during the dynamic
change and flow rate phases. The minimum piping size is 3/8” for the pump type 008, 016 and 022, while it should be at least 1/2” for the
pumps type 036 and 046, 3/4” for the 070 and 100 pumps type.
The drain tube has to unload inside the tank far from the suction area.
- No check valves allowed on the suction line. As for details and the installation of filter elements, see paragraph 2.3.
- The motor-pump connection must be carried out directly with a flexible coupling, to reduce at the minimum the axial and radial loads on the
pump shaft. The alignment tolerance between the two shafts must be within 0.05 mm.
