Solar SlowPump
The Dankoff Solar SlowPump was the world’s first commercially available low power solar pump. In response to those that claimed it was impossible, the Solar SlowPump was developed by Windy Dankoff in 1983 and has thousands of installed units worldwide over its nearly 40-year life. Produced in a wide range of sizes, the Slow SlowPump is used to draw water from shallow sources and push it as high as 450 vertical feet through miles of pipeline. Designed for reliability and maintainability, wear parts typically last 5-10 years, with an overall life expectancy of 15-20 years before rebuild.
Output: 0.2 – 6.2 GPM (0.75 – 23 LPM)
Max Total Dynamic Head (TDH): 560 ft. (170m)
Suction Capacity: 20 vertical feet (6 m) at sea level. Subtract 1ft. for every 1000ft. altitude (1 m for every 1000 m)
Weight: 12 – 29lbs (5-13kg) – Dependent on model
Notes: MUST be filtered clean (reference spec. sheet); 15 – 20 year life expectancy
Warranty: 1 year against defects in materials and workmanship
