4.0HP Doyin DYM-S04 AC Borehole Pump Controller for 4SDM3/40 – Automatic Protection, Single-Phase Control, Pump Safety

Product Overview

The 4.0HP Doyin DYM-S04 AC Borehole Pump Controller is specifically matched to the Doyin 4SDM3/40 4.0HP single-phase borehole submersible pump, providing dedicated electrical control for this higher-power pumping configuration.

Designed for demanding borehole installations, the DYM-S04 provides a central interface between the AC supply and the 4SDM3/40 pump motor. The 4.0HP rating makes this combination suitable for deeper boreholes, elevated storage tanks, farms, estates and light commercial water-supply systems where stronger pumping capability is required.

Macire verifies controller-to-pump compatibility before supply and provides technical guidance on correct cable sizing, earthing and electrical protection. Proper installation of the DYM-S04 is particularly important with a 4HP motor to minimise voltage drop and support dependable long-term operation.

Installation & Engineering Notes

Install the DYM-S04 in a dry, ventilated and weather-protected location. Confirm that the connected pump is the specified 4.0HP Doyin 4SDM3/40 before commissioning.

Because of the higher 4HP motor rating, cable cross-section and cable-run length require careful consideration to minimise voltage drop. Correct earthing, supply voltage and upstream electrical protection are also essential.

Macire can provide technical guidance for correct controller, pump and electrical-system matching.

Care, Maintenance & Operations

• Keep the controller clean, dry and properly ventilated.
• Inspect terminals periodically for looseness or overheating.
• Maintain effective electrical earthing.
• Inspect supply and borehole cables for deterioration.
• Ensure the controller remains protected from rain and flooding.
• Investigate repeated trips or difficult pump starting promptly.
• Have electrical repairs carried out by qualified technicians.
• Use correctly matched Doyin replacement components.

Do’s & Don’ts

Do’s
