Doyin 4SF5-230-4000W (5.5HP) AC/DC Hybrid Borehole Submersible Pump

The Doyin 4SF5-230-4000W (5.5HP) AC/DC Hybrid Borehole Submersible Pump is a heavy-duty industrial-grade borehole pump engineered for extreme-depth water extraction and high-pressure water delivery. Powered by a 4,000W (5.5HP) high-efficiency brushless motor, this premium hybrid pump operates seamlessly on both AC power (grid or generator) and DC solar power, providing uninterrupted water supply for demanding commercial, agricultural, industrial, and community applications.

With an impressive maximum pumping head of 345 metres and a maximum flow rate of 8,400 litres per hour (8.4m³/h), the Doyin 4SF5-230-4000W AD is specifically designed for deep boreholes where standard submersible pumps cannot perform effectively. Its heavy-duty stainless steel construction offers exceptional corrosion resistance and durability for continuous underwater operation, while the brushless motor delivers superior efficiency, lower maintenance, and extended service life.

Designed for large-scale solar water pumping systems, this hybrid borehole pump provides a dependable and energy-efficient solution for deep commercial boreholes, industrial water supply, large irrigation projects, and off-grid community water schemes.
