SFLO SP7Hybrid AC/DC Solar pump

Typical Applications

Medium and deep boreholes with solar as the primary power source and AC mains as backup.
Domestic and institutional water supply, livestock watering, drip irrigation and tank filling.
Very deep boreholes and hilly terrain requiring high total dynamic head.
Schemes where pumping must continue during poor solar conditions using AC mains.

Construction

Impellersand diffusers:stainless steel, floating-style to remove axial thrust from the motor bearing. This is the only difference from the SD range, which uses a thermoplastic wet end.
Casing, shaft, coupling and inlet base: stainless steel AISI 304.
Motor: brushless DC permanent-magnet, water-filled and rewindable,with thrust bearing sized for the full stage stack.
Shaft seal: mechanical seal behind a sand guard.
Inlet: stainless screen; outlet BSP female to the size tabulated.
Cable: 100% copper, water- and UV-resistant, with heat-shrink splice kit. Enclosure: pump IP68; controller IP65 for outdoor wall mounting in shade.
