4HP 4.8m³/h 287m Doyin 4SD3/40 Ordinary Impeller Borehole Pump Body

The 4HP 4.8m³/h 287m Doyin 4SD3/40 Ordinary Impeller Borehole Pump Body is built specifically for very deep boreholes where exceptional vertical lifting capability is required.

Its standout specification is the impressive 287m maximum head, giving the 4SD3/40 considerably more lifting capability for demanding deep-well installations. It delivers up to 4.8m³/h (4,800 litres per hour) when correctly paired with a compatible 4HP borehole motor.

The ordinary impeller configuration provides a practical hydraulic solution for clean borehole-water pumping, while the combination of 287m head and 4,800L/h flow makes this model particularly suited to deep groundwater extraction and elevated storage systems.

This is the pump body only, allowing it to be used for a new 4HP pump assembly or as a replacement hydraulic section where a compatible motor is already available.

Important Compatibility Note

This product is the Doyin 4SD3/40 borehole pump body only – the motor is not included.

It should be coupled with a compatible 4HP borehole pump motor. Actual operating head and flow depend on the complete installation, including dynamic water level, pipe losses and system resistance.

Installation Notes

• Pair with a compatible 4HP borehole motor
• Confirm pump-body and motor coupling compatibility
• Check borehole depth and diameter
• Determine static and dynamic water levels
• Calculate total dynamic head
• Confirm sustainable borehole yield
• Correctly size delivery piping
• Professional assembly and installation are recommended
