QXEH2

The QXEH range are single-stage units that use just one pair of gear wheels. Their compact and heavy-duty construction introduces a new and pioneering benchmark for pumps. The improved dimensional stability of all rotating components results in higher overall rigidity levels, and this in turn decisively enhances the performance ratings of the QXEH pumps. In addition, a vital improvement to the hydrodynamic lubrication of the ring gear has been implemented by regulating the flow profiles in the critical bearing areas by means of selective oil supply. The good inlet characteristics, and the extremely low noise emissions, even at high speed, are ensured by our tried and tested special gear-tooth technology.

Advantages

  •    -  generates high pressures in just one stage
  •    -  simple and compact construction
  •    -  resists cavitation with critical fluids
  •    -  very low noise levels
  •    -  maximum reliability, also for reverse mode
  •    -  extremely long service live
  •    -  pressure and flow pulsations are minimal
  •    -  ideally suited for use with variable-speed drives
