4HP 3kW 4″ Doyin Single-Phase Borehole Pump Motor

The 4HP 3kW 4″ Doyin Single-Phase Borehole Pump Motor delivers substantial drive power for deep boreholes and demanding high-lift water-pumping installations.

Its 3kW (4HP) output provides a clear step up in drive capacity from the 3HP model, allowing it to power compatible pump bodies requiring greater motor strength.

The 4-inch submersible design is built for integration with compatible borehole pump bodies. Importantly, it combines this higher 4HP capacity with single-phase operation, making it practical for installations where three-phase electricity is not available.

This is the motor section only, suitable for assembling a correctly matched borehole pump or replacing a compatible 4HP submersible motor.

Important Compatibility Note

The 4HP / 3kW rating refers to motor power, not the final pump head or flow.

Actual metres of head and litres per hour depend on the specific pump body and impeller stages coupled to this motor. Always match it with a compatible 3kW / 4HP pump body.

Installation Notes

• Match with a compatible 4-inch pump body
• Confirm the pump body requires 3kW / 4HP
• Verify the available single-phase AC supply
• Use correctly sized submersible electrical cable
• Install suitable overload and motor protection
• Ensure correct pump-to-motor coupling
• Include dry-run protection where required
• Professional borehole installation is recommended

Mini FAQ

What is the motor capacity?
It is rated at 4HP / 3kW / 3000W.

What diameter is it?
It is a 4-inch submersible borehole motor.

Is this model single-phase?
Yes. It is specifically a single-phase AC borehole motor.
