Internal Gear Unit QXM for Motor/Pump Service
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 saving
- - Up to 20 dB (A) quieter
- - Saving valve technology
- - Operating pressure up to 400 bar
- - Open and closed circle operation
- - Use with variable-speed drives
- - 2 and 4 quadrant operation possible
