End-suction EN733 centrifugal pumps SES and SKS
Directly off the shelf - centrifugal pumps for clean water
The end-suction centrifugal pumps SES and SKS meet the requirements of versatile water applications. The long-coupled pump SES and the close-coupled (monoblock) pump SKS are certified for drinking water.
- Water supply facilities
- Water distribution networks
- Irrigation
- Heating and cooling systems
- General industry applications
SES is a long-coupled pump that can be delivered as a complete skid or as bare shaft pump connected to an existing electric motor.
SKS is a close-coupled (monoblock) pump with electric motor that can be supplied with a frequency converter.
SKS is a close-coupled (monoblock) pump with electric motor that can be supplied with a frequency converter.
Main design features
- Suitable for high-pressure applications with flanges in PN 10 and PN 16
- “Back pull-out” design makes it possible to remove hydraulic parts without having to remove the pump body from the plant pipes
- Dynamically balanced closed impeller to minimize radial loads and provide smooth rotation of impeller
- Suction profile designed to reduce NPSH for trouble-free operation in demanding conditions
- Stainless steel shaft designed to withstand the bending-torsion load
- Oversized ball bearings provide reduced working noise and a long service life
- Large selection of mechanical seals or gland packings (SES) configured according to the requirements of the fluid characteristics and conditions of use
Optional features
- Easy replaceable wear rings to protect the pump body and the impeller (standard for larger sizes)
- SES: Oil-lubricated bearings with a constant level oil feeder
