High Pressure Hydraulic Vane Pump, VQ Series

The VQ series hydraulic pump is a high-pressure, high-performance composition vane pump specially developed for construction machinery, especially mobile machinery.

Hydraulically balanced composition vanes, resisting higher pressure up to 21 MPa Floating side plates which can compensate clearance automatically to reach balance, providing superior performance under high rotating speed and high pressure. Bimetallic flexible side plates on each side of the motor dramatically improve the gears' engagement performance, giving higher efficiency and longer service life. Technical Parameters
