Samking Solar Submersible Pump – AD-4SPW2-09P (1800W AC/DC Hybrid)
 
The Samking AD-4SPW2-09P Solar Submersible Pump is a high-capacity AC/DC centrifugal pump designed for agricultural, community, and off-grid water supply applications. Its hybrid design allows operation directly from solar panels or the AC grid, ensuring reliable water availability even in remote areas or during load shedding.
Built with a 304 stainless steel body and a water-filled motor, the pump provides excellent cooling, long service life, and dependable performance in boreholes up to 150 m maximum submersion depth. The external hybrid controller offers real-time operating status and advanced protection for safe and stable operation.
Ideal for agricultural irrigation, borehole pumping, livestock watering, community water supply, elevated tanks, and solar-powered water systems.
