The Staffa HMC series dual displacement piston hydraulic motor models have two pre-set displacements which can be chosen from a wide range to suit specific application requirements.

HMC series hydraulic motor with high torque, low speed radial piston motors use hydrostatic balancing techniques to achieve high efficiency, combined with good breakout torque and smooth running capability.
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.

Key Product Features:
-- Replacement of original Kawasaki Staffa motor of same series.
-- Consistent, controlled acceleration of loads with smooth, steady, low speed operation.
-- Moving parts are immersed in hydraulic fluid, so Staffa motors do not require periodic lubrication.
-- Save money by increasing usable drive power and reducing drive train maintenance.
-- The only fully hydrostatically balanced design in the industry.
-- Less wear and superior starting torque because there is minimal metal-to-metal contact within the motor.
