2.2kW 6.6m³/h 154m Doyin 4SP5-25 3HP 6600L/h Stainless Steel Impeller 3-Phase Borehole Submersible Water AC Pump

The 6.6m³/h Doyin 4SP5-25 Stainless Steel Borehole Pump Body is designed for deep borehole installations requiring substantial water-lifting capability and reliable flow. With a maximum flow capacity of 6.6m³/h (6,600 litres per hour) and a maximum head of 154 metres, it is particularly suited to high-head groundwater applications.

The 4SP5-25 multistage hydraulic configuration progressively develops pressure to move water from deep boreholes to surface-level or elevated storage systems. Its stainless steel construction provides the strength and corrosion resistance required for long-term submerged operation.

This model is suitable for farms, residential properties, institutions and commercial facilities where both depth and water demand must be considered. Macire supplies verified Doyin pumping equipment and provides technical guidance on correct motor selection, borehole sizing and system configuration.

Installation & Engineering Notes

Correct selection should consider borehole depth, static water level, dynamic water level, required flow, elevation and total dynamic head.

The pump body must be paired with a correctly sized and compatible submersible motor. Appropriate delivery piping, electrical cables, non-return valves, overload protection and dry-run protection should also be selected according to the installation.

Macire can provide technical guidance on matching the Doyin 4SP5-25 to the intended borehole system.

Care, Maintenance & Operations

1. Monitor water output and pressure regularly.
2. Prevent operation under dry-run conditions.
3. Inspect electrical controls and protection equipment.
4. Check delivery pipes and connections for leakage.
5. Investigate sudden reductions in water flow.
6. Keep the system within its designed operating conditions.
7. Maintain adequate borehole water levels during operation.
8. Use compatible components when servicing the pumping system.

Do’s & Don’ts

Do’s

• Determine the required water flow before installation.
• Use a correctly matched submersible motor.
• Install dry-run and overload protection.
• Use appropriately sized delivery piping.
• Have the system installed by a competent borehole technician.

Don’ts

• Do not run the pump without adequate water.
• Do not use an incorrectly sized motor.
• Do not select the pump based only on borehole depth.
• Do not operate against a closed discharge.
• Do not install without electrical protection.
• Do not exceed the intended operating conditions.

Compatibility

Compatible with appropriately selected:

• Submersible borehole motors
• Doyin automatic pump controllers
• Doyin water-level sensors
• Dry-run protection devices
