Durable Deep Well Performance: USK 0.5HP 4SDM Series
The USK 4SDM307 is engineered for longevity and consistent pressure. As a multi-stage centrifugal pump, it uses seven precision-engineered impellers to lift water vertically with ease, making it a favorite for homeowners who need a dependable, low-maintenance water solution.
Key Performance Features:
Multi-Stage Impeller System: Uses a 7-stage design to achieve a high vertical lift (50m head) while maintaining a steady pressure for household taps and tanks.
Stainless Steel Construction: Both the pump and motor external casings are crafted from high-grade stainless steel (AISI 304) for maximum corrosion resistance in submerged environments.
Quiet & Efficient Cooling: Being fully submerged, the pump operates silently as the surrounding water dampens motor noise and provides natural cooling for the 0.37kW motor.
Borehole Compatible: Specifically designed with a slim 4-inch (98mm) diameter to fit perfectly into standard borehole casings used in Kenya.
No Priming Required: Since the unit is installed within the water source, it remains naturally primed, eliminating the air-lock issues common with surface pumps.
High-Torque Copper Motor: Built with 100% pure copper wire windings to ensure high efficiency and a long operational lifespan even during extended running periods.
Thermal Protection: Includes built-in safeguards to protect the motor against overheating or power fluctuations.
