Liebherr pumps of the DPVP series are used predominantly in excavators. An upstream spur gearbox facilitates downspeeding to reduce exhaust gas emissions.
Hydraulic component - Axial piston pump
Circulation - open
Adjustability - variable
Nominal pressure - 400 bar
Maximum pressure - 450 bar
Nominal sizes - 108 / 108 impeller / 165 / 165 impeller
Areas of application - Building construction and civil engineering
The Liebherr axial piston pump DPVP series is developed
for the open circuit in swash plate design as a parallel pump.
The variable pump is available in nominal sizes 108 – 108 and
165 – 165 cm³. The nominal pressure is 400 bar and maximum pressure 450bar.
Special features of the DPVP:
These pumps are specially designed for excavator applica-
tions. Due to an integrated gear, a downspeeding to fullfill
higher emission standards is possible. To obtain higher max-
imum speed and flow for size 165 – 165, an impeller version
is also available if required. Thanks to the inverted piston
design with 22° swivel angle, high efficiency and power
density are obtained. The DPVP series is available with the
most common controls.
