America's #1 Most Trusted Solar-Powered Water Pump
RPS Solar Pump Kits are for people that believe in getting the job done themselves, and getting it done right. Our goal is to arm you with the equipment and knowledge to take control of your water and save a fistful of money doing it. Our Pledges to You 

The newly redesigned Narrow pump is a miraculous 2.01" in diameter and the first of it's kind. Yes, it can sneak in next to an existing pump/drop-pipe in a 6" well casing to act as a backup redundant pump, or if a pump is stuck down in the well. It fits 2.5" and 3" casings that are so common in old windmills. Finally a solution for windmill wells that could never take a submersible pump before!! 

Like our 3" pumps it features a helical rotor. These pumps are designed to operate on solar power alone and feature a brushless DC motor to keep temperature down and efficiency up in a tight well casing. And to give you more flexibility and peace of mind, batteries or a generator can be used to supplement as needed. The most efficient brushless permanent magnet motors mean no replacement of carbon brushes and years of smooth, reliable performance. Lifetime Rotor Warranty and the only field-serviceable pump available save you thousands over other options.
