HPB Motors – High Power Single Displacement

Our Staffa HPB radial piston motors have increased speed and power ratings compared to the original Staffa HMB motor.  The Staffa HPB range allows our customers to increase their machine productivity, whilst providing the proven reliability of a Staffa motor.

The Staffa HPB radial piston motor is the perfect fixed displacement motor for the most demanding of industrial applications.

  • Higher power density = more compact machinery
  • Higher speed rating = user productivity gains
  • Market-leading reliability = less down time
  • No flushing circuit = less machine cost
