Doyin 4SF5-300-5500W (7.5HP) AC/DC Hybrid Borehole Submersible Pump

The Doyin 4SF5-300-5500W (7.5HP) AC/DC Hybrid Borehole Submersible Pump is a heavy-duty, industrial-grade water pump engineered for extreme-depth boreholes and high-demand water supply applications. Powered by a 5,500W (7.5HP) high-efficiency motor, this advanced hybrid pump operates on both AC power (grid) and DC solar power, ensuring continuous and reliable water supply regardless of power availability.

With an exceptional maximum pumping head of 412 metres and a consistent flow rate of 8,400 litres per hour (8.4m³/h), the Doyin 4SF5-300-5500W AD is designed to handle some of the deepest boreholes while maintaining stable water pressure and high output. Its stainless steel motor housing, copper windings, and corrosion-resistant multistage construction provide superior durability, efficiency, and long service life even in harsh borehole environments.

Optimized for large solar water pumping systems with a recommended 14 × 550W solar panel configuration, this pump is an excellent solution for commercial agriculture, industrial facilities, institutions, community water projects, and remote off-grid installations.
