5.5kW 6.6m³/h 357m Doyin 4SP5-58 7.5HP Stainless Steel Impeller 3-Phase Borehole Submersible Water AC Pump

The 7.5HP Doyin 4SP5-58 Stainless Steel Borehole Pump Body is engineered for ultra-deep and very high-head borehole applications requiring substantial water-lifting capability. Designed for pairing with a 7.5HP submersible motor, it delivers up to 6.6m³/h (6,600 litres per hour) with a maximum head of approximately 357 metres.

Its 58-stage multistage hydraulic configuration progressively develops the pressure required to lift groundwater through substantial vertical distances. This makes the 4SP5-58 particularly suited to demanding installations where conventional lower-head borehole pumps cannot achieve the required total dynamic head.

The stainless steel construction provides durability and corrosion resistance for prolonged submerged operation. With its combination of 357m maximum head and 6,600L/h flow, it is suitable for deep boreholes serving farms, institutions, estates and commercial water systems. Macire provides verified Doyin products together with technical guidance on correct system sizing.

Installation & Engineering Notes

The 357m maximum head should not be interpreted as the recommended borehole depth. Correct pump selection requires calculation of the total dynamic head (TDH), including dynamic water level, vertical elevation, discharge requirements and friction losses through the pipework.

The 4SP5-58 should be paired with a correctly selected 7.5HP submersible motor, appropriate electrical cable, delivery piping, non-return valves and motor-control equipment.

Dry-run and overload protection are recommended. Macire can provide technical guidance when selecting compatible pump-system components.

Care, Maintenance & Operations

1. Monitor water output and system pressure regularly.
2. Prevent operation under dry-run conditions.
3. Maintain appropriate overload and motor protection.
4. Inspect electrical cables and control equipment periodically.
5. Check delivery pipes, joints and valves for leakage.
6. Investigate unexpected reductions in water flow or pressure.
7. Keep operation within the correctly engineered hydraulic range.
8. Use compatible components and spares during maintenance.

Do’s & Don’ts

Do’s

• Calculate the installation’s total dynamic head.
• Confirm the sustainable borehole yield.
• Pair the pump body with a compatible 7.5HP motor.
• Install suitable dry-run and overload protection.
• Correctly size the electrical cable and delivery pipe.
• Use a qualified borehole technician for installation.

Don’ts

• Do not interpret 357m maximum head as borehole depth.
• Do not operate the pump without adequate water.
• Do not use an incorrectly rated motor.
• Do not operate against a blocked discharge.
• Do not install without suitable electrical protection.
• Do not ignore changes in flow, pressure or motor current.

Performance Guide

Actual water output depends on total dynamic head, borehole yield, pipe diameter, friction losses and the complete pumping-system configuration.

Mini FAQ

1. What is the maximum flow of the Doyin 4SP5-58?
The pump body delivers up to 6.6m³/h, equivalent to approximately 6,600 litres per hour.

2. What is its maximum head?
The Doyin 4SP5-58 has a maximum specified head of approximately 357 metres, making it suited to very high-head pumping applications.

3. What motor should be paired with it?
