Doyin 4SF10-234-9200w (12.5HP) AD — AC/DC Hybrid Submersible Borehole Pump

The Doyin 4SF10-234-9200w is the flagship of the 4SF10 series — a supreme 12.5HP AC/DC hybrid submersible pump built for the most extreme borehole depths and the most demanding water supply requirements. Reaching a maximum head of 400 metres while pushing out 14,400 litres per hour, it operates seamlessly on solar or grid power, making it the ultimate choice for large-scale commercial, industrial, and off-grid water projects where depth, volume, and reliability must all be maximised.
