Radial Piston Motors

STAFFA HMC Dual Displacement Motor

Staffa's performance and reliability is well documented with over 35 years of successful applications worldwide. Staffa motors are the choice of industry leaders to directly propel, drive, swing, or rotate heavy loads and inertias at low speeds.

All over the world, Staffa motors are used on: plastic injection molding machines (extruder screw drives), mining machinery (swing, track, wheel, bucket, and cutterhead drives), earthmoving and construction equipment (wheel, track, swing and implement drives), marine machinery (winch and steering mechanisms), and forestry machines (swing and cutterhead drives) as well as many others.

Staffa motors are offered in models that include single displacement, dual displacement and continuously variable forms supplemented by integral gearboxes, brakes, and standard valve packages.

Staffa motors offer consistent, controlled acceleration of loads and smooth, steady, low speed operation. Moving parts are immersed in hydraulic fluid, so Staffa motors do not require periodic lubrication.

They also save money by increasing usable drive power and reducing drive train maintenance.

Utilizing the only fully hydrostatically balanced design in the industry, Staffa motors wear less and have superior starting torque because there is minimal metal-to-metal contact within the motor.

A modular design concept has enabled the motor to be continuously adapted to the changing needs of our customers. This concept also allows product availability and service to be matched to market requirements.

All motors are rigorously tested and documented before shipment and are fully warranted.
