The QXM drive unit can be used in open- and closed-loop hydrostatic drives, and can operate both as a pump and as a motor.
The QXM works as a pump to lift the load and it can recover energy when the load is being lowered.
Used as a bi-directional pump / motor (four-quadrant operation), the unit can control the complete motion cycle of a cylinder.
