Staffa Radial Piston Motors

In 1916, over 100 years ago, Kawasaki began manufacturing Hele-Shaw type radial piston pumps – only the second ever product in the world designed for use with hydraulic oil.

Now we lead the hydraulics industry in scale and production facilities, manufacturing a wide range of products, from hydraulic pumps, motors, valves, various hydraulic components and electric controllers, to hydraulic systems for mobile, industrial and marine machinery, and many other applications.

More than 60 years ago, in 1957, the first ever hydraulic radial piston motor was designed by George Hally junior, previously a Hercules radial aircraft engine designer, he named it the “Staffa” motor.

Originally designed to work in the harsh environment of a coal mine, the Staffa motor was quickly found to be a tough and reliable product, it soon became popular wherever a reliable direct drive solution was required.

In the decades that have followed, using all the experience gained from working closely with customers in industries including construction, materials handling, marine winches, plastic injection moulding machines and vehicle drives, Kawasaki Precision Machinery engineers have advanced and refined the motor’s design.

Today, modern techniques such as finite element analysis, advanced materials and coatings, computational fluid dynamics and state-of-the-art testing facilities enable us to continue to push the operating boundaries of this unique family of motors.

Over 500,000 motors have now been sold, many of which are still in daily use, after thousands of hours in trouble-free service.

Kawasaki Staffa motors are all made at our advanced and modern manufacturing facility in Plymouth, Devon, United Kingdom, where we continue to invest millions of pounds in the latest production technology. This has enabled us to continually improve our manufacturing processes, maintaining the world leading quality and reliability of Kawasaki Staffa products.

*NEW* HPB Motors

The HPB motor is the latest innovation in the Staffa range. With increased speed and power ratings compared to our standard HMB motor, it can increase productivity whilst providing the reliability you would expect from a Staffa motor. The new Staffa HPB motor is the perfect fixed displacement motor for industrial applications.

>Ideal fixed displacement motor for industrial applications
>Higher power density = more compact machinery
>Higher speed rating = user productivity gains
>Even higher efficiency = reduced user costs
>Market-leading reliability = less down time
>Long life = high return on investment
>Useable ratings = REAL power
>Fast technical support = satisfied customers
>No flushing circuit = less machine cost
