Liebherr LH30VO Axial Piston Hydraulic Pump is manufactured specially for open circuits in mobile and stationary applications. These pump can be operated with through-drive up to 130% because of the type of pressure and swashplates of these pumps.

LH30VO is popular for their flexibility of the drive design, It has modular control model kit, that help to provides more than 35 possible control combinations, some of them are discussed below.

Power control (LR)
Electrical volume flow control (VE) with rising characteristic
and additional jump function at signal loss (VK)

Liebherr LH30VO pumps are developed for all kinds of most common applications, which consists driving equipment, ventilation, or steering of a machine. This allows increased performance and the optimised production and assembly processes make the LH30VO an attractive and high-performing product.
