The 50m Doyin 4SDM3/7 AC Borehole Submersible Water Pump is designed for shallow boreholes where high water output, low electricity consumption and reliable daily performance are essential. Powered by a 0.37kW (0.5HP) copper-wound AC motor, it delivers up to 4.8m³/h (4,800 litres per hour) while pumping water to a maximum head of 50 metres.

Unlike many small-capacity borehole pumps that struggle to maintain adequate flow, the 4SDM3/7 is engineered with a multi-stage Ordinary Impeller that produces excellent discharge for domestic water systems, livestock watering, greenhouse irrigation and overhead storage tanks. Its hydraulic design prioritises water volume, making it an ideal choice where borehole depth is moderate but daily water demand is high.

The pump features a corrosion-resistant stainless steel body, precision-machined shaft and heavy-duty mechanical seals to ensure dependable operation throughout years of continuous service. Its compact 4-inch diameter allows easy installation in standard boreholes, making it a cost-effective solution for homeowners, farmers and small businesses.

Supplied and verified by Macire, every genuine Doyin pump is backed by expert technical advice, nationwide delivery and dependable after-sales support.
