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
