7.5kW 18m³/h 166m Doyin 4SP15-26 10HP 18000L/h Stainless Steel Impeller 3-Phase Borehole Submersible Water AC Pump

The 10.0HP Doyin 4SP15-26 Stainless Steel Borehole Pump Body is designed for high-volume, high-head borehole water systems where substantial quantities of groundwater must be moved efficiently. Designed for pairing with a 10.0HP submersible motor, it delivers up to 18.0m³/h (18,000 litres per hour) with a maximum head of approximately 166 metres.

Its 26-stage multistage hydraulic configuration develops the pressure required for deep-water lifting while supporting considerably higher water delivery. With an 18,000L/h maximum flow, the 4SP15-26 is particularly suited to large farms, irrigation storage, institutions, estates and commercial facilities with substantial daily water requirements.

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

Installation & Engineering Notes

Correct selection of the Doyin 4SP15-26 should consider the dynamic water level, sustainable borehole yield, required operating flow, delivery elevation, pipe friction losses and total dynamic head.

Because the pump body can deliver up to 18,000L/h, verifying the borehole’s sustainable yield is particularly important. An undersized or low-yield borehole may experience excessive drawdown during high-flow operation.

The pump body should be paired with a compatible 10.0HP submersible motor, appropriately sized electrical cables, delivery pipes, non-return valves and control equipment. Dry-run and overload protection are recommended.

Care, Maintenance & Operations

1. Monitor operating flow and pressure regularly.
2. Ensure the borehole can sustain the required water withdrawal.
3. Use suitable dry-run protection.
4. Maintain correctly rated motor-overload protection.
5. Inspect electrical cables and control equipment periodically.
6. Check delivery pipes, valves and fittings for leakage.
7. Investigate significant reductions in flow or pressure.
8. Use compatible replacement components during servicing.

Do’s & Don’ts

Do’s

• Confirm the borehole’s sustainable water yield.
• Calculate the installation’s total dynamic head.
• Match the pump body with a compatible 10HP motor.
• Install suitable dry-run and overload protection.
• Correctly size the delivery pipe and electrical cable.
• Use a competent borehole technician for installation.

Don’ts

• Do not operate if the borehole cannot sustain the required flow.
• Do not interpret the 166m maximum head as borehole depth alone.
• Do not pair the body with an incorrectly rated motor.
• Do not operate against a closed or blocked discharge.
• Do not install without appropriate electrical protection.
• Do not ignore abnormal changes in flow or pressure.

Compatibility

Compatible with appropriately selected:

• 10.0HP submersible borehole motors
• Doyin automatic pump controllers
• Doyin water-level sensors
• Dry-run protection systems
• Borehole control panels
• Motor overload protection
• Non-return valves
• Large elevated storage tanks
• Irrigation storage reservoirs
• Commercial water-distribution systems
• Correctly engineered solar pumping systems

Performance Guide

Actual operating flow depends on total dynamic head, sustainable borehole yield, pipe diameter, friction losses and complete pumping-system configuration.
