5.5kW 7.5HP Doyin 3-Phase AC Borehole Pump Controller – Three-Phase Control, Motor Protection, Reliable Operation

Product Overview

The 5.5kW 7.5HP Doyin 3-Phase AC Borehole Pump Controller is designed for controlling compatible 5.5kW (7.5HP) three-phase AC borehole pump motors. Its higher 7.5HP capacity makes it suitable for demanding borehole installations where substantial pumping power is required for deep-well water abstraction, elevated tank filling or continuous water transfer.

The controller provides a dedicated electrical interface between the three-phase supply and pump motor, supporting controlled starting, operation and shutdown. It is particularly suited to farms, commercial properties, institutions, estates and other higher-demand water systems.

Macire supplies and verifies the controller according to the intended motor rating and provides technical guidance on cable sizing, electrical protection and three-phase configuration. Correct professional installation is essential for reliable operation of a 5.5kW borehole pumping system.

Installation & Engineering Notes

The controller should be connected to a compatible three-phase AC electrical supply and correctly rated 5.5kW (7.5HP) three-phase borehole pump motor.

At this motor rating, cable sizing is particularly important. Cable cross-section should account for operating current, borehole depth and total cable length to minimise voltage drop. Appropriate electrical isolation, earthing and upstream protection should also be provided.

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 weather exposure.
• Inspect terminals periodically for looseness or overheating.
• Maintain secure and effective electrical earthing.
• Check the condition of all three supply phases.
• Inspect pump cables for damage or deterioration.
• Maintain adequate ventilation around the controller.
• Investigate repeated trips or abnormal motor behaviour immediately.
• Use qualified technicians for servicing and electrical repairs.

Do’s & Don’ts

Do’s

• Use with a compatible 5.5kW / 7.5HP three-phase pump.
• Verify all three supply phases before commissioning.
• Size cables according to motor load and installation distance.
• Provide appropriately rated electrical protection.
• Maintain effective system earthing.
• Have the system professionally commissioned.

Don’ts
