HMC Series – Dual Displacement Hydraulic Motors

The HMC range provides an additional level of control and versatility for Staffa motor applications. The dual displacement motor an be tailored to meet the requirements of the application with low displacement settings available from 0 – 90% of the high displacement setting.

The benefits provided for applications such as winches are immense and allow a HMC motor to perform operations that may previously have required more than one motor.

Standard Options

  • The displacement listed above are for indication, there are a full range of displacement ranging from 0cc/rev (free wheel) to the maximum displacements listed in the table above.
  • All standard options for the HMB series are available for the HMC series
  • Power control option provides continuous variation of the displacement to maintain a set power limit
  • Continuously variable displacement option is available which uses a PLC based system to provide accurate control over output torque and speed.
  • A number of displacement change options are available ranging from pilot ports to Cetop 3 interfaces with internal shuttle for pressure supply.

Due to the nature of the dual displacement motor there are numerous non standard options. For further details please contact us
