QXM Internal Gear Units

Description

Pump/motor operation in multi-quadrant applications

The QXM series is an extension of the QX pump series and is suitable for operation as both a pump and a motor. Thanks to the completely symmetrical design, these units can be used in multi-quadrant operation and are suitable for a wide range of applications in both industrial and mobile hydraulics. In 4-quadrant operation, the movement of cylinders can be controlled on the one hand, and exploited to recover/save energy on the other. For example, if the unit works as a pump during a lifting process, it can then work as a motor during the lowering process to feed energy back into the system.

Avantages

  • Open/closed circuits up to 400 bar max. working pressure
  • Low noise level < 75 dB(A)
  • Particularly suitable for multi-quadrant operation
  • Can be used with all hydraulic fluids
  • Can be used with fixed- and variable-speed drives
