5.5HP 4.8m³/h 358m Doyin 4SD3/50 Ordinary Impeller Borehole Pump Body

The 5.5HP 4.8m³/h 358m Doyin 4SD3/50 Ordinary Impeller Borehole Pump Body is engineered for ultra-deep boreholes where extreme vertical lift is the main pumping requirement.

Its defining specification is the exceptional 358m maximum head. Combined with a maximum flow of 4.8m³/h (4,800 litres per hour), the 4SD3/50 provides a powerful hydraulic solution for extracting water from substantial depths and delivering it to elevated storage points.

Designed to work with a compatible 5.5HP borehole motor, this pump body uses an ordinary impeller configuration and is particularly suited to clean borehole-water applications.

This is the pump body only, making it ideal for building a correctly matched 5.5HP pump assembly or replacing the hydraulic section of an existing compatible borehole pump.

Important Compatibility Note

This listing is for the Doyin 4SD3/50 borehole pump body only – motor not included.

It should be correctly paired with a compatible 5.5HP borehole pump motor. Actual operating head and flow will depend on the installation depth, dynamic water level, delivery piping and overall system resistance.

Installation Notes

• Pair with a compatible 5.5HP borehole motor
• Confirm motor-to-pump coupling compatibility
• Check borehole diameter and installation depth
• Determine static and dynamic water levels
• Calculate total dynamic head
• Confirm sustainable borehole yield
• Correctly size the delivery pipe
• Professional assembly and installation are recommended
