3kW 6.6m³/h 203m Doyin 4SP5-33 3000W 4HP Stainless Steel Impeller 3-Phase Borehole Submersible Water AC Pump

The 4.0HP Doyin 4SP5-33 Stainless Steel Borehole Pump Body is designed for demanding deep-borehole installations where exceptionally high water-lifting capability is required. Designed for pairing with a 4.0HP submersible motor, it provides a maximum flow of 6.6m³/h (6,600 litres per hour) and a maximum head of approximately 203 metres.

Its 33-stage multistage hydraulic configuration develops the pressure required to move groundwater through substantial vertical distances, making it particularly suitable for deep boreholes and elevated storage systems. Stainless steel construction provides the durability and corrosion resistance needed for long-term submerged operation.

With its combination of 203m head and 6,600L/h maximum flow, the 4SP5-33 is suited to farms, institutions, residential developments and commercial water systems. Macire supplies verified Doyin pumping equipment and provides technical guidance on correct pump, motor and borehole-system matching.

System Architecture & Configuration

33-Stage Hydraulic System

The 4SP5-33 uses a multistage hydraulic configuration designed to progressively generate pressure for deep and high-head water lifting.

High-Head Performance

A maximum head of approximately 203 metres makes this model particularly suited to demanding deep-borehole installations.

Water Delivery

Provides a maximum flow of 6.6m³/h, equivalent to approximately 6,600 litres per hour, depending on operating head.

Stainless Steel Construction

The stainless steel pump body provides strength and corrosion resistance for prolonged submerged operation.

Motor Configuration

Designed for pairing with a compatible 4.0HP submersible borehole motor.

Installation & Engineering Notes

The 203m maximum head should not be interpreted as borehole depth alone. Correct sizing should account for static water level, dynamic water level, vertical lift, delivery elevation, pipe friction and required operating flow.

Pair the 4SP5-33 with a correctly selected 4.0HP submersible motor and suitable electrical cable, delivery pipe, non-return valve, control panel and protection equipment.

Dry-run and overload protection are recommended. Macire can provide technical guidance based on the borehole and intended water-demand requirements.

Care, Maintenance & Operations

1. Monitor flow and pressure during normal operation.
2. Prevent the pump from running without adequate water.
3. Inspect electrical protection and control equipment periodically.
4. Check delivery pipes, valves and fittings for leakage.
5. Investigate unexpected reductions in water output.
6. Keep the pump within its intended operating conditions.
7. Maintain appropriate overload and dry-run protection.
8. Use compatible components during servicing and replacement.

Do’s & Don’ts

Do’s

• Confirm the required total dynamic head.
• Check the borehole’s sustainable water yield.
• Match the body with a compatible 4.0HP motor.

• Use correctly sized delivery pipes and cables.
• Have installation completed by a competent borehole technician.

Don’ts

• Do not operate without sufficient borehole water.
• Do not pair the pump body with an incorrectly rated motor.
• Do not use the 203m head figure as borehole depth alone.
• Do not operate against a closed discharge.
• Do not install without appropriate electrical protection.
• Do not ignore significant changes in flow or pressure.
