TECHNICAL SPECIFICATIONS

16 100/112 ED

— The VPPM pumps are variable displacement axial-piston pumps

with variable swash plate, suitable for applications with open circuits.

— They are available in three different frame sizes with maximum

displacements up to 29, 46, 73 and 87cm

/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.

— The pumps feature medium-high working pressures (up to 280 bar

constant and 350 bar peak). Thanks to some particular design

features, these pumps are able to bear high axial and radial loads on

the shaft.

— They are usually supplied with a ISO 3019/2 mounting ﬂange, with

the exception of the rear and intermediate pumps, if multiple pumps,

which are only available with a SAE J744 2-holes ﬂange and a

SAE J744 splined shaft (see paragraph 16).

— They are available with seven different types of regulating control,

each according to the application needs (see paragraphs 8 ÷ 14).

2 - HYDRAULIC FLUID

2.1 - Fluid type

Use mineral oil based hydraulic fluids with anti-foam and antioxidant additives according to the DIN 51524 norm.

For use with other types of fluid, keep in mind the limitations shown in the following table or consult our technical department for

authorization of use.

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 15÷ 35 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

10 (c)

≥ 75 is suggested.

A degree of maximum ﬂuid contamination according to ISO 4406:1999 class 18/16/13 is recommended for optimum endurance of the pump.

Hence, the use of a ﬁlter with β

10 (c)

≥ 100 is recommended.

In the event that the ﬁlter is installed on the suction line, be sure that the pressure at the pump inlet is not lower than the values speciﬁed in the

table of paragraph 3.

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.

9 - REMOTE-CONTROLLED PRESSURE REGULATOR: PCR

FUNCTIONAL DIAGRAM

The PCR regulator, apart from limiting the line maximum pressure

(P valve), 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.

N.B. The maximum length of the connection between the valve and

the pump X port must not be longer than 2 m.

PCR FEATURES:

- pressure regulating range (P) = 20

÷ 350 bars

- default setting (P) = 280 bars

- remote-regulated pressure range = 14 ÷ 315 bars

- ﬂow rate available on the X port for the remote-control = about 1,5 l/min

This type of regulator allows to select, by means of a three-position

solenoid valve, two different working pressures; it allows also the

pump unloading.

The solenoid valve (1) and the relief valve (2) for the intermediate

pressure setting are directly installed on the pump regulator and

they are to be ordered separately.

PCX FEATURES (two pressure settings + unloading):

- solenoid switching valve (1) = DS3-S2 (to be ordered separately

see catalogue 41 150)

- solenoid valve OFF = pump unloading - delivery pressure = 20 bar

- solenoid side “a” ON = maximum displacement and delivery

pressure set on relief valve (2) (intermediate value)

- solenoid side “b” ON = maximum displacement and delivery

pressure set on regulator (P) (maximum value)

- pressure relief valve (2) = MCI*-SBT (to be ordered separately -

10 - REGULATOR WITH PRESSURE CONTROL DEVICES: PCX

10.1 - Electrical unloading

FUNCTIONAL DIAGRAM

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 (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

OUT

D2IN

This regulator allows an independent regulation of the pump ﬂow

and pressure, both with an electric proportional control.

The pump ﬂow is regulated through the proportional valve (1) which

operates directly on the pump delivery, while the system pressure is

controlled by means of the proportional relief valve (2) working as a

pilot stage of the differential regulator (Q).

The maximum system pressure is limited by the regulator (P). The

regulator is also equipped of a built-in pressure relief valve (3) with

manual adjustment, which limits the pressure peak due to quick

ﬂow variations in the system.

PQCE5 FEATURES

- pressure regulating range (P) = 20 ÷ 350 bar

- default setting (P) = 280 bar

- differential pressure regulating range (Q) = 10 ÷ 30 bar

- default setting = 16 bar

- proportional pressure regulating range:

20 ÷ 250 bar (for VPPM-*PQCE5 pump)

- proportional ﬂow regulating range:

0 ÷ 69 l/min (for VPPM-046 PQCE5 pump)

13.1 - Characteristic curves of the PQNC regulator (values obtained with mineral oil with a viscosity of 36 cSt at 50°C)

The diagram curves were measured with a pump rotation speed of 1500 rpm and an oil temperature of 50°C.

FLOW RATE / PRESSURE CURVE

Such regulator keeps the pump torque at a constant level by changing the

displacement according to the delivery pressure, so that the ratio p x (Q)

(absorbed power) remains unchanged. The functions limiting the (P)

maximum pressure and regulating the (Q) ﬂow rate are always present, if a

restrictor has been installed on the user line.

In the 1/8” BSP coupling supplied for the X port, there is a restrictor of Ø0,8

oriﬁce.

Note: The connection pipe between the X port and the pump outlet must

always be made (customer charge).

PQNC FEATURES:

- pressure regulating range (P) = 20 ÷ 350

- default setting (P) = 280 bar

- differential pressure regulating range (Q) = 10 ÷ 30 bar

- default setting = 16 bar

- min. discharge head = 18 ± 2 bar

(with a zero ﬂow rate, X discharge pilot and with a default Q setting of

the differential regulator)

- the power regulator is factory set. The setting value has to be speciﬁed

with the order, by stating into the identiﬁcation code the Nm torque value

(see paragraph 1).

20 - INSTALLATION

- The VPPM pumps can be installed both in a horizontal and vertical position, with the shaft in an upward position.

N.B.: 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 (according to the

installation use the D1 or D2 drainage ports).

- Installation below the oil reservoir is suggested. As for an installation above the oil level, check that the min. suction 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 that the drain tube

is adjusted so that the pump higher bearing can be always lubricated.

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

- It is necessary to vent the air from the delivery connection before operating it the first time. 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 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 2 bar (absolute), even during the dynamic

change and flow rate phases. The drainage tube has to unload inside the tank far from the suction area. We suggest to interpose a screen

between the two lines.

- The drain pressure can be max 0.5 bar higher than the suction pressure but it can never exceed the max of 2 bar of absolute pressure.

- No check valves allowed on the suction line.

- The motor-pump connection must be carried out directly with a flexible coupling. Radial and axial loads have to be lower than the values

specified in the table at paragraph 3.

- As for details and the installation of filter elements, see par. 2.3.

21 - THROUGH OUTPUT SHAFT

The VPPM pumps can be supplied with a through output shaft, which allows coupling with other pump models.

N.B.: The pumps with a through output shaft are supplied with an intermediate 2-hole flange type SAE J744 - and with a mating joint

for splined shaft type SAE J744.

The mechanical adjustment for the min and max displacement are not available on these front or intermediate pumps: VPPM-029

with flange 62S, VPPM-073 with flange 64S, VPPM-087 with flange 64S.

As for identification see par. 1 “Identification code”. For the pump overall dimensions (intermediate flange included) see paragraph 23

“overall dimensions for multiple pumps”.

22.1 - Max. applicable torque

The input torque (M) for each pump is given by the following ratio:

M =

9550

= [Nm]

where the absorbed power (N) is given by:

N =

∆

= [kW]

600

tot

or it can be obtained from the diagrams ABSORBED POWER (see par. 4 - 5 - 6 -7).

If several pumps are coupled, the torque of each single pump has to be added to the torque of subsequent pumps when they are loaded

simultaneously.

The obtained torque value for each pump has to be lower than the value speciﬁed in the table below :

The maximum transmissible torque for those pumps with a through output shaft is determined by the coupling used for the transmission. If the

obtained torque values are higher than the ones stated in the table, it is necessary to reduce the working pressure value or to replace the

overloaded pump with a pump suitable to bear the required torque.

n = rotation speed [rpm]

Q = ﬂow rate [l/min]

∆p = differential pressure between the pump suction and delivery [bar]

tot

= total efﬁciency (obtainable from the diagrams in par. 4-5-6)

22 - MULTIPLE PUMPS

The possibility to couple several pumps makes it possible to create multi-ﬂow groups with independent hydraulic circuits.

While sizing coupled pumps, it’s necessary to make reference to the following conditions:

- The coupling can be carried out between pumps with the same dimensions or to a size of decreasing order.

- The max. rotation speed is determined by the pump with the lowest speed.

- The values of the max. applicable torque can not be exceeded.
