UPA S 200 and UPA S 250 in detail
With the UPA S 200 and UPA S 250 well pumps, KSB offers two powerful and highly efficient units for well diameters from 8 or 10 inches. Both models are available in numerous designs with a range of options – offering you the perfect variant to match your requirements.
Many more benefits, much more UPA!
The models from the UPA pump range are mainly used for drinking water and general water supply, general irrigation / spray irrigation, groundwater management, offshore applications and pressure boosting. Alongside their exceptionally low energy requirements, these pumps impress with outstanding operating reliability, durability and a long motor life:
- Excellent efficiency thanks to optimised hydraulic systems and smooth surfaces (investment casting)
- Optimum adjustment to the customer’s operating point thanks to freely configurable number of stages and custom impeller trimming
- Outstanding corrosion resistance thanks to high-grade stainless steel design
- Highly resistant to wear thanks to metal casing wear rings and optional SiC plain bearings for handling fluids containing large amounts of sand.
- Reliable operation thanks to improved lift check valve in anti-blockage design
- Continuous motor operation thanks to water-lubricated, maintenance-free plain bearing with self-aligning tilting pads
- Counter thrust bearing for reliably absorbing negative axial thrust
- Wear protection thanks to mechanical seal in carbon/ceramic or ceramic/ceramic material combination
- Reliable pressure equalisation system for maximum immersion depths
- Motors designed for maximum pump input power to prevent overloading
