5.5HP 4kW 4″ Doyin 3-Phase Borehole Pump Motor

The 5.5HP 4kW 4″ Doyin 3-Phase Borehole Pump Motor delivers serious drive power for deep boreholes, high-lift pumping and demanding agricultural water systems.

Rated at 4kW (5.5HP), this model provides significantly greater drive capacity than the smaller 4HP motor, making it suitable for compatible pump bodies requiring stronger power for demanding pumping duties.

Its compact 4-inch submersible configuration is designed for integration with compatible borehole pump bodies. The three-phase AC architecture makes it particularly suitable for commercial farms, irrigation projects and high-demand water installations with three-phase electricity.

This is the motor section only, making it suitable for building a correctly matched pump assembly or replacing a compatible 5.5HP submersible borehole motor.

Important Compatibility Note

The 5.5HP / 4kW specification represents the motor’s drive power. The final borehole pump’s head, flow rate and litres-per-hour output depend on the pump body and impeller configuration connected to the motor.

Always pair it with a compatible 4-inch 4kW (5.5HP) borehole pump body.

Installation Notes

• Match with a compatible 4″ pump body
• Confirm the pump body requires 4kW / 5.5HP
• Verify the correct three-phase AC supply
• Use correctly sized submersible electrical cable
• Install suitable overload and motor protection
• Ensure correct motor-to-pump coupling
• Include dry-run protection where required
• Professional borehole installation is recommended

Mini FAQ

What is the motor power?
5.5HP / 4kW / 4000W.

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