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