QXEHX Internal Gear Pumps

Description

Highly dynamic pump operation with very high speeds

The QXEHX series is the successor to the QXEH series, and brings new advantages with it. In addition to optimized hydrodynamic lubrication, the speed range has now been extended up to 5000 rpm. With increased power density and improved operational reliability, this surpasses even the benefits offered by the QXEH series. This makes QXEHX pumps particularly suitable for downsizing the entire drive train, e.g. in injection molding and die casting machines, while at the same time achieving a long service life.

Advantages

  • Open circuits up to 280 bar max. working pressure
  • High speeds up to 6,050 rpm
  • Low noise levels < 75 dB(A)
  • Specially for highly dynamic drives with a reversing function
  • Can be used with almost all hydraulic fluids
  • Can be used with fixed- and variable-speed drives
