Description:

The A10VO is a variable displacement axial-piston pump built by Bosch Rexroth for open-circuit hydrostatic drives. Featuring a swash-plate design, the pump allows stepless adjustment of flow and pressure via variation of the swash-plate angle. Compact yet powerful, the A10VO offers high power density, reliable suction characteristics, and excellent efficiency — making it well suited for construction machinery, mobile hydraulics, agricultural equipment and industrial hydraulic systems.
