4kW 14.4m³/h 120m Doyin 4SP10-20 5.5HP 14400L/h Stainless Steel Impeller 3-Phase Borehole Submersible Water AC Pump

The 5.5HP Doyin 4SP10-20 Stainless Steel Borehole Pump Body is designed for borehole installations requiring high-volume water delivery combined with substantial lifting capability. Designed for pairing with a 5.5HP submersible motor, it delivers up to 14.4m³/h (14,400 litres per hour) with a maximum head of approximately 120 metres.

The 4SP10-20 multistage hydraulic configuration is engineered to develop the pressure needed to lift groundwater while maintaining a significantly higher flow rate. Its 14,400L/h maximum delivery makes it particularly suitable for farms, irrigation storage, large estates, institutions and commercial facilities with substantial daily water requirements.

Stainless steel construction provides durability and corrosion resistance for prolonged submerged operation. Macire supplies verified Doyin borehole pumping products and provides technical guidance on motor matching, borehole yield, total dynamic head and system configuration.

Installation & Engineering Notes

Correct selection of the Doyin 4SP10-20 requires consideration of dynamic water level, borehole yield, required operating flow, delivery elevation, pipe friction and total dynamic head.

Because this model can deliver up to 14,400L/h, confirming the borehole’s sustainable yield is particularly important. Installing a high-flow pump in a low-yield borehole may cause excessive drawdown and dry running.

Pair the pump body with a compatible 5.5HP submersible motor and correctly sized delivery pipes, electrical cables, non-return valves and control equipment. Macire can provide guidance on appropriate system sizing.

Care, Maintenance & Operations

1. Monitor water flow and system pressure regularly.
2. Confirm adequate borehole water availability during operation.
3. Install suitable dry-run protection.
4. Maintain appropriate motor-overload protection.
5. Inspect electrical connections and control equipment periodically.
6. Check delivery pipes and valves for leakage or restriction.
7. Investigate significant reductions in flow or pressure.
8. Use compatible components during servicing and replacement.

Do’s & Don’ts

Do’s

• Confirm the borehole’s sustainable water yield.
• Calculate the required total dynamic head.
• Match the pump body with a compatible 5.5HP motor.
• Install appropriate dry-run and overload protection.
• Correctly size delivery pipes and electrical cables.
• Use a competent borehole technician for installation.

Don’ts

• Do not install in a borehole unable to sustain the required flow.
• Do not interpret the 120m maximum head as borehole depth alone.
• Do not pair with an incorrectly rated motor.
• Do not operate against a closed or blocked discharge.
• Do not operate without adequate electrical protection.
• Do not ignore significant changes in water output.
