Variable displacement pump
Highlights
The DPVG axial piston variable displacement pump for closed circuits, with a through drive of up to 130 percent of the torque, is designed for extreme loads, high reliability, and long service life. It provides the ideal solution for a wide range of applications and drive systems across various industries. The use of hydrostatic swashplate bearings in nominal sizes 85, 140, and 280 minimises wear and ensures outstanding performance.
