DOYIN 4SDM3/10 0.75HP AC Submersible Pump — With 30m Cable, 1.25" Outlet

The DOYIN 4SDM3/10+30m Cable is a dependable 0.75HP single-phase AC submersible pump with an ordinary impeller, built for domestic wells and shallow-to-mid boreholes. With a 1.25-inch outlet and a flow rate of 4.8m³/h (4,800 litres per hour), it delivers reliable performance for a recommended depth of up to 64 metres, with a maximum head of 72M.

This variant comes with a factory-fitted 30-metre submersible cable already attached, saving on separate cable purchase and installation time — a convenient, ready-to-install option for wells within that depth range. It suits domestic wells, household water points, and general home water supply needs across coastal Kenya, including Mombasa, Malindi, Diani, Kilifi, and Lamu.

Running on standard single-phase AC power, it's a practical option for properties without three-phase supply. As with the standard 4SDM3/10, this pump requires a matching AC controller (DOYIN's DYM-S03 unit) sized to its 0.75HP rating for correct, protected operation. It is not solar-compatible and is best suited to properties with stable single-phase grid or generator power.

CoastalSolar Africa supplies, sizes, and installs the 4SDM3/10+30m Cable pump, including the correctly matched DYM-S03 controller, across the coastal region.

FAQs:

What's included with the 30m cable version vs the standard model?
This variant comes with a 30-metre submersible cable already fitted to the pump, ready for installation — useful if your well depth is within that range and you want to avoid buying cable separately.

What if my well is deeper than 30m?
You'd need additional cable beyond the pre-fitted length, or CoastalSolar Africa can advise on the standard (no-cable) 4SDM3/10 with custom cable length instead.

What controller does this pump need?
It requires the DOYIN DYM-S03 AC controller, specifically matched to this model — CoastalSolar Africa can supply and fit this correctly.

Is this a solar pump?
No — it's a single-phase AC pump requiring standard grid or generator power. For solar-powered options at a similar power level, ask about DOYIN's DC pump range.

Do you install this pump in Kilifi and Malindi?
Yes, CoastalSolar Africa supplies and installs the 4SDM3/10+30m Cable pump with its matched controller across Mombasa, Malindi, Diani, Kilifi, Lamu, and the wider coastal region.
