4kW 8.4m³/h 345m Doyin 4SF5-230-4000W AD 5.5HP 8400L/h Borehole Submersible Water AC/DC Hybrid Pump

The 4kW Doyin 4SF5-230-4000W AD AC/DC Hybrid Pump is a high-lift borehole pump built for extremely deep water applications.

Its powerful 4kW (5.5HP) motor delivers up to 8.4m³/h (8,400 litres per hour). This provides substantial water volume for demanding agricultural and water-storage systems.

The key capability is its impressive 345m maximum head. This makes it particularly suitable for very deep boreholes and installations requiring water to be lifted over significant vertical distances.

Its AC/DC hybrid configuration provides flexible operation with correctly designed solar or compatible AC power systems.

The combination of 345m head and 8,400L/h maximum flow makes this model particularly suited to commercial farms, irrigation, livestock projects and high-elevation tank filling.
