Internal Gear Unit QXM

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

• Very low noise levels
• Negligible pressure pulsations
• Long service life
• Suitable for special fluids
• 4-quadrant (fully bi-directional pump / motor) or
• 2-quadrant operation is possible
• Low susceptibility to cavitation
