3kW 4.8m³/h 287m Doyin 4SD3/40 4HP Ordinary Impeller 3-Phase Borehole Submersible AC Water Pump

The 3kW Doyin 4SD3/40 3-Phase Borehole Submersible AC Water Pump is built for deep boreholes where high lifting capability is more important than extremely high flow.

Its 3kW (4HP) motor delivers up to 4.8m³/h (4,800 litres per hour).

The standout specification is its 287m maximum head. This gives the pump strong vertical lifting capability for deep boreholes and elevated water-storage systems.

The ordinary impeller configuration provides a practical pumping solution for clean borehole water.

Its three-phase AC operation makes it particularly suitable for farms, commercial properties and installations with an available three-phase electricity supply.
