QXEM Internal Gear Units

Highly dynamic variable-speed multi-quadrant applications

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.
