Type WRX

Robust, highly wear-resistant single-stage centrifugal pump with closed impeller and wear plates on suction and bearing side.


  • Pumping of media with high sliding wear as well as on mechanical impact by high levels of coarse grain (grain size up to 200 mm)
  • The design allows the use of very hard materials => min. 550 HB
  • Suction: axial
  • Discharge: tangential
  • Axially adjustable impeller
  • Shaft sealing by stuffing box or mechanical seal
  • Various impeller shapes are possible (e.g. 2- or 3-vaned)
  • Different arrangements available (e.g. vertical)
  • Back pullout design (the complete rotating assembly can be removed while the casing remains on its position)
  • Durable, oil or grease lubricated bearings
  • Direct or belt driven
  • Usage as underwater pump through special assemblies possible
  • Counterclockwise rotation design possible
