QXM Pump
Internal Gear Unit for Motor/Pump Service, 5,1 – 498,5 Displacement cm³/rev.
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. This flexibility offers possibilities for various applications, one example being the raising and lowering of loads. The QXM works as a pump to lift the load and recovers energy when the load is being lowered.
Used as a fully bi-directional pump/motor (four-quadrant operation), the unit controls a complete motion cycle of a cylinder. Fast acceleration/deceleration sequences can be achieved. The unit is based on the well-known QX internal gear pump, which is distinguished by its very low noise levels and almost imperceptible pressure pulsations. A large number of closely spaced sizes ensures that the right size is always available for every application.
ATEX compliant explosion protection. The internal gear unit QXM is suitable for application in hazardous areas and complies with the following guidelines:
- ATEX directive 2014/34/EU
- Group II
- Equipment category 3
- Atmosphere G
- Temperature class T3 & T4
