— The VPPL are variable displacement axial-piston pumps withvariable swash plate, suitable for applications with opencircuits and intermediate pressures.

— They are available in five nominal sizes, with displacementsof 8, 16, 22, 36 and 46 cm3/rev.

— The pump flow rate is proportional to the rotation speed andto the angle of the swash plate, which can be continuouslymodulated. The maximum and minimum angle can be limitedmechanically via suitable regulating screws.

— They are usually supplied with a SAE J744 2-hole flange anda SAE J744 cylindrical with key shaft.

— They are available with three different types of regulatingcontrol, each according to the application needs.

2 - HYDRAULIC FLUID

2.1 - Fluid type

Use mineral oil based hydraulic fluids, type HH, HL or HM according to ISO6743-4 standards.

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 fluidoptimum viscosity 20 / 50 cSt referred to the operating temperature of the fluid in the tankmaximum 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 NAS 1638 class 9; therefore the use of a delivery or return filter with β20≥ 75 is suggested.A degree of maximum fluid contamination according to NAS 1638 class 7 is recommended for optimum endurance of the pump. Hence, theuse of a filter with β10 ≥ 100 is recommended.For the installation of filters on the suction line, see par. 8. The suction filter must be equipped with a by-pass valve and, if possible, with aclogging indicator and should be oversized to avoid cavitation problems.

The PC5 pressure regulator keeps the pressure at a constantset level in the circuit, thus adjusting automatically the pumpflow rate according to the real need of the system.

The desired pressure can be set by manually adjusting the Pregulation valve. The clockwise rotation of the adjustment boltmakes the pressure increase.

FEATURES OF THE PC REGULATOR:

- P pressure adjustment range = 40 ÷ 210 bar

VPPLSERIES 10

4.2- REMOTE-CONTROLLED PRESSURE REGULATOR: PCR

OUT

IN D2 D1

X

Escluso dalla fornitura The PCR regulator allows a remote-control of the device via aremote control connected to the X port (typical application forsubmerged pumps).

In case a pressure regulating valve is used for the remote-control, itis suggested to use a direct operated valve with a size suitable to1,5 l/min pilot flow rate.

Note: The maximum length of the connection between the valveand X port of the pump must not be longer than 2 m.

FEATURES OF THE PCR 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 PC5model), allows the pump flow rate control, according to the ∆ppressure drop measured on either side of a throttle valve installedon the user line.

Note: The connection pipe between the X port and the flow linedownstream the restrictor (or valve) must always be made(customer charge).

FEATURES OF THE PQC REGULATOR:

- P pressure adjustment range = 40 ÷ 210- Q differential pressure adjustment range = 16 ÷ 28 bar- minimum delivery pressure = 20 bar

8 - INSTALLATION

- The VPPL pumps can be installed both in a horizontal and vertical position, with the shaft in an upward position.Note: The drainage 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 min. suction pressure is not lower than -0.2 bars (relative). If a low noise emissionlevel 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 that the drain tubeis adjusted so that the pump higher bearing can be always lubricated.

- Before starting, the pump body has to be filled with the fluid.

- Check the rotation direction of the pump.

- 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 aventing valve is recommended. The pump start up, especially at a cold temperature, should occur with the plant at minimum pressure.

-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 anexcessive tube length could further decrease the value of the suction pressure with a following increase in the noise emissions and adecrease 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 thedynamic 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. The drainage 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 par. 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 thepump shaft. The alignment tolerance between the two shafts must be within 0,05 mm.
