Hydraulic Motors

HPC Series

The enhanced variable displacement HPC models include special low friction components, combined with crankcase flushing flow, to achieve increased shaft power. It is used around the world in marine and offshore winch applications and is known for its efficiency and reliability.

Main Features:

  • 1,344 to 6,555cc displacements in 6 frame sizes
  • 250 bar continuous pressure rating
  • Dynamic displacement change
  • Freewheel option available
  • Constant horsepower control option

    • Bearing Life:

    Consideration should be given to the required motor bearing life in terms of bearing service life. The factors that will determine these include:

    • Duty cycle – Time spent on and off load
    • Speed
    • Differential Pressure
    • Fluid Viscosity, type, cleanliness and temperature
    • External radial shaft load
    • External axial shaft load
