The 210m Doyin 4SPS4.5-1500W DC Borehole Pump is the highest-head model in Doyin’s 4SPS Stainless Steel Impeller Series, engineered for demanding deep borehole installations where exceptional lifting capability, hydraulic efficiency and long-term reliability are essential. Its stainless steel multi-stage impeller assembly offers superior resistance to corrosion, abrasion and wear, making it ideal for continuous operation in challenging borehole conditions.

Powered by a 1.5kW (2HP) brushless DC permanent magnet motor, the pump delivers up to 4.5m³/h (4,500 litres per hour) while lifting water to an impressive maximum head of 210 metres. This makes it an excellent solution for mountainous terrain, deep boreholes, elevated storage tanks and commercial water distribution systems where conventional pumps struggle to maintain pressure.

For optimum daily performance, Macire recommends pairing this model with 4 × 550W high-efficiency solar panels together with a compatible MPPT solar pump controller. This configuration provides reliable off-grid pumping while eliminating electricity and fuel costs.

Supplied and verified by Macire, this premium Doyin pump is ideal for agricultural, commercial, institutional and large residential water projects requiring dependable long-term performance.
