Windmill to Solar Kit For Livestock - 2" & 3" Solar Water Pumps for Windmills
🎉 New Year Solar Savings Sale FREE SHIPPING* (Ends 1/31!)
Looking to replace an old windmill without tearing it all down?
Finally a solution for windmill wells that could never take a submersible pump before!! RPS carries two options to retrofit a windmill well, the first is our RPS 200, RPS 400 and RPS 800 3" Submersible Pumps that fit a 3.5" or larger well-casing. The second option is the now famous Narrow pump series RPS 200N, RPS 400N and RPS 800N measuring a miraculous 2.01" in diameter and the first of its kind. The narrow series fits 2.5" casings that are so common in old windmills. And yes, it can also 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.
Our 2" and 3" pumps feature 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.
The RPS 200 and RPS 200N use 2 x 100W panels
The RPS 400 and RPS 400N use 4 x 100W panels
The RPS 800 and RPS 800N use 8 x 100W panels
Common Questions:
Can I keep my old windmill in place?
Yes! Because our systems use flexible poly-pipe instead of rigid PVC, it's an easy swap to carefully pull out the old PVC piping and slide the poly-pipe and pump down the well without having to tear down your windmill. Keep the windmill for decoration on the ranch as a staple of the American way of life!
Can I mount solar panels on my old windmill?
Yes! Many of our happy customers have created their own easy ways to attach their panels to their old trusty windmill frame. Watch our as he shows some great examples or !
