Solar Slowpump
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, homeowners, missionaries,
health workers, government agencies,
etc. Some of our oldest Slowpumps are
still in daily service.
Slowpump is not submersible, but can
draw water from shallow wells, springs,
cisterns, tanks, ponds, rivers, and
streams, and push it as high as 450
vertical feet and through miles
(kilometers) 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 a much
wider range of sizes. Wearing parts
typically last 5 to 10 years. Overall
life expectancy is 15 to 20 years.
