7.5HP 5.5kW 4″ Doyin 3-Phase Borehole Pump Motor

The 7.5HP 5.5kW 4″ Doyin 3-Phase Borehole Pump Motor is a high-capacity submersible drive designed for deep boreholes and demanding water systems requiring considerably more pumping power.

Its 5.5kW (7.5HP) output provides a major increase in drive capacity over smaller 4HP and 5.5HP motors, making it suitable for compatible pump bodies designed for heavier pumping duties.

The 4-inch submersible configuration combines substantial motor power with a compact borehole format. Its three-phase AC operation makes it particularly suitable for commercial farms, large irrigation systems and high-demand water installations with three-phase electricity.

This product is the motor section only, allowing it to be paired with a correctly selected pump body or used to replace a compatible 7.5HP submersible motor.

Important Compatibility Note

The 7.5HP / 5.5kW rating represents motor drive power, not the final pump’s water output.

The completed borehole pump’s maximum head, flow rate and litres-per-hour capacity depend on the specific pump body and impeller stages connected to this motor.

Always match it with a compatible 4-inch 5.5kW (7.5HP) borehole pump body.

Installation Notes

• Match with a compatible 4″ pump body
• Confirm the pump body requires 5.5kW / 7.5HP
• Provide a correctly rated three-phase AC supply
• Use correctly sized submersible power cable
• Install appropriate overload and motor protection
• Ensure secure motor-to-pump coupling
• Provide dry-run protection where required
• Professional borehole installation is recommended

Mini FAQ

What is the motor power?
7.5HP / 5.5kW / 5500W.

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