DOYIN 4SPS7-1500W (2.0HP) AD Hybrid Stainless Steel Submersible Pump — 1.5" Outlet

The DOYIN 4SPS7-1500W is a durable 2.0HP AD (hybrid) submersible pump with a stainless steel impeller, capable of running on solar power or standard AC electricity. With a 1.5-inch outlet and a flow rate of 7.0m³/h (7,000 litres per hour), it delivers reliable performance from a recommended depth of up to 99 metres, with a maximum head of 165M — the entry point into DOYIN's 4SPS7 hybrid pump range.

The stainless steel impeller offers added corrosion resistance, making this a solid choice for coastal boreholes in Mombasa, Malindi, Diani, Kilifi, and Lamu, where water can carry higher mineral content or mild salinity. As an AD hybrid model, it can run on a solar array during daylight hours (DC 160–400V) and switch to single-phase AC power (220–240V) when solar output drops, giving continuity of water supply during cloudy periods or higher demand.

This pump suits domestic boreholes, farm irrigation, and community water points needing dependable output regardless of solar conditions. The solar configuration pairs with a 4 x 550W panel array to reach the correct operating voltage.

CoastalSolar Africa supplies, sizes, and installs the 4SPS7-1500W pump and its solar array or AC power setup across the coastal region.

FAQs:

How many solar panels does this pump need?
It requires 4 x 550W panels, roughly 2.2kW total, to reach its 160–400V DC operating range.

Can this pump run on AC power only, without solar?
Yes, its AD hybrid design allows full operation on single-phase AC power alone (220–240V) if a solar array isn't installed or available.

Is the stainless steel impeller worth it for coastal boreholes?
Yes, it offers better resistance to mineral content and mild salinity often found in coastal borehole water compared to ordinary impeller pumps.

How does this compare to the 4SPS7-2200W (3.0HP)?
Both share the same 1.5" outlet and 7,000L/h flow, but the 2200W model reaches greater depth (134M vs 99M recommended) at a higher 3HP rating, using more panels (6x550W vs 4x550W).

Do you supply and install this pump in Kilifi and Malindi?
Yes, CoastalSolar Africa supplies and installs the 4SPS7-1500W pump and its solar array across Mombasa, Malindi, Diani, Kilifi, Lamu, and the wider coastal region.
