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.
Used as a bi-directional pump / motor (four-quadrant operation), the unit can control the complete motion cycle of a cylinder. The QXM works as a pump to lift the load and it can recover energy when the load is being lowered.
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
Applications
- - injection molding machines
- - hydraulic presses
- - flight simulators
- - wind-power plants
- - lift/elevator drives
- - winches
- - marine industry
