Efficiency and Case Drain Flows
Efficiency, power consumption

Axial Piston Pump
Series PV
Efficiency and case drain flows PV032 to PV046
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 compensa-
tors 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 60 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.

Pressure Compensators
Axial Piston Pump
Series PV
Standard pressure compensator, code MMC
The standard pressure compensator adjusts the pump
displacement according to the actual need of the system
in order to keep the pressure constant.
As long as the system pressure at outlet port P is lower
than the set pressure (set as spring preload of the inte-
grated pilot valve) the working port A of the compensator
valve is connected to the case drain and the piston area
is unloaded. Bias spring and system pressure on the an-
nulus area keep the pump at full displacement.
When the system pressure reaches the set pressure of the
pilot valve, pilot flow is built up and a differential pressure
will occur at pilot orifice BV.When this differential pressure
reaches the factory setting of the compensator, the control
spool connects port P1 to A and builds up a pressure at
the servo piston resulting in a down stroking of the pump.
The displacement of the pump is controlled in order to
match the flow requirement of the system.
Remote pressure compensator, code MRC
The basic function of the remote pressure compensator
code …MRC is equal to the function of the standard pres-
sure compensator. The remote compensator offers an
additional remote control port on the side of the compen-
sator body. With a remote installed pilot valve, the setting
of the pump compensating pressure can be adjusted from
a location up to 15 meter apart from the pump.
The thread of this remote port is defined in the thread
option of the PV pump ordering code.
For long distances between pump and remote control
valve please consider temperature and response time
influences.
Standard pressure compensator with NG6 interface,
code MM1
With code …MM1 the standard pressure compensator
has on its top side a valve interface size NG 6 DIN 24
340 (CETOP 03 acc. RP35H, NFPA D03). This interface
allows the mounting of accessories like multiple pressure
selectors without the need of external piping and valve
mounting.
