Solar Slowpump was the world's first commercially available low power solar pump. It was developed by windy Dankoff in 1983, in response to those who said "that's impossible". Thousands of Slowpumps have been installed worldwide by Ranchers, Health Workers, Villages, Governments agencies. Slowpump is not submersible, but can draw water from shallow wells, springs, cisterns, tanks, poinds, rivers and streams, and push it as high 450 vertical feet, and through miles of pipeline. Slow pumping minimizes the size and cost of the solar array, wire and piping. Slowpump is less expensive than submersible DC pumps, and made in much wider range of sizes. wearing parts typically last 5 to 10 years. Overall life expectancy is 15 to 20 years. |
