3.0kW 4HP Doyin 3-Phase AC Borehole Pump Controller – Three-Phase Control, Motor Protection, Reliable Operation

Product Overview

The 3.0kW 4HP Doyin 3-Phase AC Borehole Pump Controller is specifically designed to control compatible 3.0kW (4HP) three-phase AC borehole pump motors. Its 4HP capacity makes it suitable for more demanding pumping installations where higher motor power is required for borehole water abstraction and transfer.

The controller provides a central electrical interface between the three-phase power supply and the connected pump, supporting controlled starting, operation and shutdown. It is suited to farms, estates, institutions, commercial properties and larger storage-tank filling systems using compatible 4HP three-phase pumps.

Macire verifies controller-to-pump matching before supply and provides technical guidance on cable sizing, three-phase configuration and electrical protection. Correct installation is particularly important with a 3.0kW motor to maintain reliable operation and protect the pumping system.

Installation & Engineering Notes

Connect the controller only to a compatible three-phase AC supply and correctly rated 3.0kW (4HP) three-phase borehole pump motor.

Cable cross-section should be selected according to motor load and total cable length, particularly for deep boreholes where voltage drop can affect motor performance. Appropriate isolation, earthing and upstream circuit protection should be installed.

Three-phase sequence and pump rotation should be verified during commissioning. Macire recommends installation by a qualified electrical or borehole-pump technician.

Care, Maintenance & Operations

• Keep the controller dry and protected from rain.
• Inspect electrical terminals for looseness or overheating.
• Maintain effective system earthing.
• Periodically verify the condition of all three supply phases.
• Check pump cables for deterioration or damage.
• Maintain adequate ventilation around the controller.
• Investigate repeated trips before restarting the pump.
• Use qualified technicians for servicing and electrical repairs.
