Our selection of centrifugal pumps in single-stage or multi-stage design.


Horizontal single-stage centrifugal pump in back pullout design.
  • Pumping of abrasive and corrosive liquids
  • All components which are in contact with the liquid are made of SICcast
  • Suction flange: Axial
  • Discharge flange: Top (Tangential)
  • Closed impeller with three-dimensionally curved vanes
  • Impeller is key driven; reverse rotation (e.g. back-flushing) is possible
  • Re-adjustable inclined gap between impeller and wear plate to optimize the efficiency and differential pressure after longer operation
  • Single acting, metal free cartridge mechanical seal DÜTEC-C with springs located outside of the liquid
  • Durable, oil-lubricated roller bearings
  • Back pullout design (the complete rotating equipment can be disassembled while the casing remains on its position)
  • In many applications the wear life of SICcast greetly exceeds conventional materials
  • The patented design allows the production of extremely large pumps at low costs
  • Currently, the most advanced and most durable technology for FGD absorber recirculation pumps
