Efficiency and case drain flows Series PV I-1.6
Efficiency, power consumption Efficiency and case drain flows
PV140, PV180, PV270
The efficiency and power graphs are measured at an input
speed of n = 1500 min-1, a temperature of 50°C and a fluid
viscosity of 30 mm2/s.
Case drain flow and compensator control flow leave via the
drain port of the pump. To the values shown are to be added
1 to 1.2 l/min , if at pilot operated compensators (codes FR*,
FF*, FT*, horse power compensator and p-Q-control) the
control flow of the pressure pilot valve also goes through the
pump.
Please note: The values shown below are only valid for
static operation. Under dynamic conditions and at rapid
compensation of the pump the volume displaced by the
servo piston also leaves the case drain port. This dynamic
control flow can reach up to 120 l/min! Therefore the case
drain line is to lead to the reservoir at full size and without
restrictions as short and direct as possible.

Electrohydraulic p/Q-control Series PV I-1.9
Proportional displacement control, code FPV
The proportional displacement control allows the adjustment
of the pumps output flow with an electrical input signal.
The actual displacement of the pump is monitored by an
LVDT and compared with the commanded displacement in
an electronic control module PQ0*-F (see opposite side).
The command is given as an electrical input signal (0 - 10V
or 0 resp. 4 - 20mA) from the supervising machine control.
The command can also be provided by a potentiometer.
The electronic control module offers a stabilized 10V source
to supply the potentiometer.
The electronic control compares permanently input
command and actual displacement and powers the propor-
tional solenoid of the control valve. A deviation from the
Proportional- commanded displacement leads to a modulation of the
displacement input current to the solenoid. The control valve then changes
control the control pressure (port A) until the correct displacement
code FPV is adjusted.
Version FPV of the proportional control does not provide a
pressure compensation. The hydraulic circuit must be
protected by a pressure relief valve.
