QXM 100-P-000063-EN

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
