1.5HP 1.1kW 4″ Doyin 3-Phase Borehole Pump Motor

The 1.5HP 1.1kW 4″ Doyin 3-Phase Borehole Pump Motor is a dedicated submersible drive for borehole systems operating on three-phase AC power.

Rated at 1.1kW (1.5HP), it provides the motor power required to drive a correctly matched 4-inch pump body for borehole water extraction, tank filling and general water-supply duties.

Its three-phase configuration differentiates it from the equivalent single-phase motor, making it suitable for installations already equipped with a compatible three-phase electrical supply.

The motor is supplied as the drive section only, allowing it to be paired with a compatible pump body or used as a replacement for a correctly matched 1.5HP borehole motor.

Important Compatibility Note

The 1.1kW / 1.5HP rating refers to motor power only. The completed pump’s flow rate and maximum head depend on the pump body and impeller stages coupled to the motor.

Always match it with a compatible 4-inch, 1.1kW / 1.5HP pump body.

Installation Notes

• Match with a compatible 4″ borehole pump body
• Confirm the pump body requires 1.1kW / 1.5HP
• Verify the correct three-phase AC supply
• Use correctly sized submersible cable
• Install appropriate motor and overload protection
• Ensure secure motor-to-pump coupling
• Provide dry-run protection where required
• Professional borehole installation is recommended
