Table A170-7/E
Proportional electrohydraulic controls for PVPC pumps
pressure-flow alternate P/Q controls, analog or digital
The variable displacement axial piston
pumps type PVPC, can be supplied with
advanced electrohydraulic proportional
controls:
• open loop pressure control;
• load sensing flow control;
• Open and closed loop P/Q controls;
They allow to perform high dynamics and
fine regulations, directly commanded from
PLC or from the machine controller. They
are available with separated driver or with
integral electronics ቢ.
New PES digital controllers, integrated to
the pump, realize alternate closed loop
controls of pressure, flow and max power
limitation. The P/Q controls are also available
with optional sequence module (LZQZR or
PERS versions) that allow to operate the
pump with minimum pressure in the circuit
close to zero. Following communication
interfaces are available for the digital PE(R)S
execution, see section :ݟ
• -PS: Serial
• -BC: CANopen
• -BP: PROFIBUS DP
For technical characteristics and features of
the PVPC pumps, see table A160.

Maximum pressure for all models with water glycol fluid is
160 bar, with option /PE is 190 bar.
Max speed with options /PE and water glycol fluid is
2000/1900/1600/1500 rpm respectively for the four sizes.
