Description

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.

Advantages

Up to 70% energy savingUp to 20 dB (A) quieterSaving valve technologyOperating pressure up to 400 barOpen and closed circle operationUse with variable-speed drives2 and 4 quadrant operation possible
