2.0HP Doyin 4SP5-18 Stainless Steel Borehole Pump Body – 6.6m³/h, 111m Head, 6600L/h

The Doyin 4SP5-18 Stainless Steel Borehole Pump Body is a high-head, high-flow pumping solution designed for boreholes and deep wells requiring dependable water transfer. Designed for use with a 2.0HP submersible motor, the pump body delivers up to 6.6m³/h (6,600 litres per hour) with a maximum head of approximately 111 metres.

Its 18-stage multistage hydraulic configuration is designed to generate the pressure required to lift groundwater from substantial depths while maintaining useful water delivery. Stainless steel construction provides durability and corrosion resistance for submerged operation.

The 4SP5-18 is particularly suitable for farms, homes, institutions and commercial properties requiring higher water volumes from deep boreholes. Macire supplies and verifies Doyin pumping products and provides guidance on correct motor matching, borehole sizing and installation.

Installation & Engineering Notes

Correct pump selection should consider borehole depth, dynamic water level, total dynamic head, required flow and pipe losses. Match the 4SP5-18 pump body with a suitable 2.0HP submersible motor.

Use correctly sized delivery pipes, non-return valves and suitable electrical protection. Dry-run protection or water-level monitoring is recommended where appropriate. Macire can provide technical guidance on pump and motor selection.

Care, Maintenance & Operations

1. Monitor water flow and pressure for unusual changes.
2. Prevent the pump from operating under dry-run conditions.
3. Inspect control and protection equipment periodically.
4. Check delivery pipes, joints and valves for leakage.
5. Maintain the pump within the recommended operating range.
6. Investigate unusual vibration, noise or reduced water output.
7. Maintain suitable electrical overload protection.
8. Consult Macire for compatible components and technical support.
