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, the RPS 400N 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. 

Find out more about all the ways you can use a submersible pump on our install diagram page or take a look at our RPS 400N customer story.

Top Notch Quality

Pump has been in since December, to a depth of 50m running off 4 x 300w panels (Locally sourced in New Zealand), and I am super impressed with it, I knew as soon as I received it the quality was top notch. Now that it's been running for a while and performance is so good, I've recommended it to other farmers, so if you get another order from New Zealand you'll know why.
I have used other pumps in the past with various degrees of success but the RPS pump is by far the best I have seen/used. The communication from your company is fantastic.
Wish you all the best in the future, and if I'm in need of another pump, you'll be the first to know.

You guys are great, love the support y’all give. Here are a few pics and a video of me testing the pump before I dropped it in the well. My little dodger man is always in the middle of my projects.
