The range of dual displacement Staffa motors extends from the HMC030 in 492 cc/rev to the HMC325 in 5,326 cc/rev. Kawasaki Staffa high torque, low speed radial piston motors use hydrostatic balancing techniques to achieve high effciency, combined with good breakout torque and smooth running capability.

The HMC series dual displacement models have two pre-set displacements which can be chosen from a wide range to suit specifc application requirements. The displacements are hydraulically selected by a directional control valve which can be remote mounted or directly on the motor. Motor displacement can be changed with ease when the motor is running.

These motors are also available in a continuously variable version using either hydro-mechanical or electro-hydraulic control methods. Other mounting options are available on request to match many of the competitor interfaces.
