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.

Applications: Travel drives of mobile machines, rotary heads of drill rigs, winch drives

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.
