Axial Piston Fixed Pump/Motor A2F

Axial piston fixed pump/motor A2F A2F can be used as either pump of motor in hydrostatic drivers, in open or closed circuit. It is axial piston unit of bent axis design with fixed displacement. If operated as a pump, the flow of A2F pump is proportional to the drive speed and displacement. If operated as a motor, the output speed of A2F motor is proportional to the swept volume and inversely proportional to displacement. The output torque increases with the pressure drop between the high and low pressure sides.
