Liebherr DPVG Axial Piston Hydraulic Pump is a type of variable displacement pump with closed loop circuits. They are available in nominal sizes, which ranges from 108 to 280 cm3 (6.59 to 17.09 in3). Minimum pressure is 450 and maximum pressure is 500 for these pumps.

The DPVG Axial Piston Pump is built with closed circuit available in swash plate design. Their number and diameter of pistons, their stroke and the space between among them in the block decides the pumping capacity of an axial piston pump. The angle of inclination of the swashplate or the bent axis is the reason behind the stroke of the pistons.

Liebherr DPVG Axial Piston Pump is known for the durability, productivity and performance, which is achieved from using hydrostatic swash plate bearings.
