GearMe gear pumps

Our gear pumps are robust and reliable. They are the ideal choice for a wide range of applications - from small to medium and large off-highway vehicles, as well as for industrial applications.

  • Pressure-balanced design, ensuring sealing pressure, adapts automatically to operating conditions for improved overall efficiency and minimum energy losses
  • Minimized internal friction and perfectly fitting housing for an extended operating life
  • Modular and short versions of multi-stage units for high flexibility and compactness
  • Teflon® coated bushings for extended life under extreme temperature and pressure conditions
  • A variety of integrated valve options
  • One piece gear shaft construction
  • Broad range of shaft drives, integrated valves, and side or rear port options gives great flexibility in system design.
  • Internal spline design option for compactness
  • Flex Program to ensure high customization in distribution
