2.98Kw 5m³ 285m Doyin 4SDS5 3000W 4.0HP 5000L/h Copper Impeller Borehole Submersible Water DC Pump

The Doyin 4SDS5 3000W DC Borehole Submersible Water Pump is a high-power, ultra-deep borehole solution engineered for extreme lifting requirements where standard pumps fall short. Delivering a strong 2.98kW (4.0HP) output, this pump achieves a remarkable maximum head of 285 meters while maintaining a stable 5.0 m³/h (5000 L/h) flow rate.

Built with a heavy-duty copper impeller and a corrosion-resistant stainless-steel body, the Doyin 4SDS5-3000W is optimized for continuous operation in demanding Kenyan borehole environments. Its DC design makes it ideal for solar-powered and hybrid pumping systems, especially in off-grid locations and rural installations where grid power is unreliable or unavailable.

At Macire, this pump is supplied as a verified, field-tested unit. Macire supports clients with correct system sizing, controller selection, installation guidance, and long-term after-sales support, ensuring dependable deep-water delivery for homes, farms, institutions, and large water projects.
