Since 1955, when the first radial piston high torque low speed motor was designed by our engineers, Staffa has maintained leadership in fulfilling customer needs.  Today, Staffa motors have the most technically advanced design on the market.

Staffa's performance and reliabilty 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.


Kawasaki Staffa motor - where power, efficiency, quality and reliability come together.
  • Modular Design:  Provides for numerous combinations of individual subassemblies and allows greater flexibility for quick response to customer needs.

  • Simple Rugged Construction:  The motor consists of 5 basic subassemblies.  This simple motor construction provides easy servicing, low maintenance costs, minimum downtime and longer operating life.

  • One Piece Casting:  Increased material strength has allowed reduction in wall sections, lighter motor weight and increased pressure ratings (3625 psi) and a higher power-to-weight ratio.

  • Environmentally Friendly:  Excellent operating characteristics with synthetic, biodegradable, and high water based fluids (HWBF) means Staffa motors are environmentally friendly and can operate in fire resistent applications.

  • Shaft Options:  Availability of both standard and customer specific special designs illustrates our commitment to responding to customer needs.
