Product Description

The Futurepump SF1 is a solar-powered irrigation pump.

The product consists of three main parts: a PV panel, to convert sunlight into electrical energy; a motor, to use the electrical energy to turn the flywheel; and a pump, to draw water out of a well, river or lake. The SF1 solar pump is robust and portable.

As of September 2020, this product has been discontinued and superceded by the Futurepump SE1 and the larger Futurepump SF2. However the Futurepump SF1 is still available for purchase from distributors with stock remaining and datasheets are still available from some distributors (Davis and Shirtliff, Condor Pumps).Interview with representative
