Description

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 Nominal sizes - 108 / 140 / 165 / 280 Areas of application - Agriculture and forestry / Building construction and civil engineering / Maritime applications 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.
