Internal Gear Motor QXEM

Pressure [bar]


Effective displacement [cm3/rev]


Speed max. motor [rpm]


Speed max. pump [rpm]


The QXEM series is intended for operation as both a pump and a motor. A symmetrical design makes these units specially suitable for highly dynamic variable-speed multi-quadrant operation. In the industrial hydraulics field, they are therefore particularly appropriate for applications with highly cyclical loading. Thanks to the pinion-shaft technology, pressures up to 250 bar are built up in a single-stage. The direction of rotation can also be reversed in milliseconds, while maximum operational reliability is ensured at all times thanks to optimized hydrodynamic lubrication.


  • Open/closed circuits up to 250 bar max. working pressure
  • Low noise levels < 75 dB(A)
  • Specially for highly dynamic multi-quadrant operation
  • Can be used with almost all hydraulic fluids
  • Can be used with fixed- and variable-speed drives
