Thanks to the use of a hydrostatic cradle bearing, the axial piston pumps for the closed circuit even impress with heavy-duty loads with their high reliability and long service life. The adjustability also enables load-independent stability of the driving mechanism.
Hydraulic component - Axial piston pump
Circulation - Closed
Adjustability - variable

The Liebherr axial piston pump DPVG series is developed
for the closed circuit in swash plate design. The variable
displacement pumps are available in nominal sizes ranging
from 108 to 280.
The nominal pressure of the units is 450 bar and the maximum pressure is 500 bar absolute.
Thanks to a hydrostatic swash plate design, this variable
displacement pump impresses with its high reliability and
long service life cycle even under toughest conditions. The
hydrostatic swash plate design is available in sizes 140 and
280, further sizes are in development.
The inverted piston design with 22° swivel angle ensures
high efficiency and great power density. The DPVG series is
available with the most common controllers.
A through-drive – just like the configuration of two DPVG
pumps to a multi-circuit pump – possible in tandem design.
