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

TyPE wr

Horizontal single-stage centrifugal pump in back pullout design.
  • Pumping of abrasive and corrosive liquids
  • Suction flange: axial
  • Discharge flange: Top (DN 32 to DN 250 vertical, from DN 300 tangential)
  • Closed and open impeller available
  • Impeller is keyed to the shaft; reverse rotation (e.g. back-flushing) is possible
  • Re-adjustable inclined gap between the impeller and volute casing to optimize the efficiency and differential pressure after prolonged operation
  • Shaft sealing by means of DÜTEC single mechanical seal with external springs (gland packing and other mechanical seals available)
  • Durable, oil-lubricated  roller bearings
  • Back pullout design (the complete rotating assembly can be removed while the casing remains on its position)
  • Optimized design ensures easy maintenance and long service life even under difficult conditions
  • Direct or belt driven
  • Different arrangements available
