Hydraulic pumps and motors
The durable axial piston pumps and motors from Liebherr feature a swashplate design. Thanks to the tough nature for high pressure ranges and optimised degrees of efficiency, they are suitable for use in a wide range of applications.
Exhibits
DMVA double motor 165-165
The DMVA motor with swashplate design can be employed as a single or double motor. Depending on the operational requirement, it can be adapted flexibly to a broad conversion range. It impresses, too, with its high performance and efficiency. DMVA double motors are, for example, used to drive Liebherr travel drives like the FAT 700.

Axial piston pump DVPVG 085
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.
