600w Samking  Solar Submersible Pump (AC/DC Hybrid)
 
The Samking AD-3SPW1-11P Solar Submersible Pump is a high-efficiency AC/DC centrifugal pump engineered for reliable water supply in residential, agricultural, and off-grid environments. Its hybrid design allows the pump to operate directly from solar panels or AC grid power, ensuring uninterrupted water availability during load shedding or in remote locations.
Manufactured with a 304 stainless steel body and designed for a maximum submersion depth of 150 m, the pump delivers excellent cooling, extended service life, and dependable performance in deep borehole applications. The intelligent external controller provides real-time operating status and advanced protection features for safe and stable operation.
Ideal for household water supply, garden irrigation, boreholes, small farms, and solar water pumping systems.
