Compare RPS with the Competition

RPS is for people that appreciate quality. For people that don’t want to leave their home or cattle without water. For people that don’t want to haul up and replace their well pumps every 6 months. For people that like to trust in their equipment – in steel not plastic. As more and more manufacturers are cutting corners, RPS remains rock solid. Designed to aerospace standards with food grade stainless. Quality you can trust for years and years to come.

Our Pledges to You

Be a company our Grandfathers would have trusted. The trend of ‘outsourcing’ customer support after the sale is a trend we wholeheartedly oppose. We are an American, family run company and our USA engineers that support you before and after the sale are the best there are. Most of our customers come from word-of-mouth, a result of treating customers with respect

No Pressure. Ever. Our Sales engineers are not on commission. We think this is important. Their role is to make sure they find the right pump for you and your well. If we don’t have a pump that will suit your needs we will help you find a solution elsewhere. Our job is to help get you water, not sell you something that isn’t a good fit.

Steady Water! All manufactured products have occasional issues and we can’t claim to be perfect. However we are proud of a PERFECT track record in getting our customers water. This starts with not selling you a pump that won’t work on your land and immediately replacing parts under warranty so you can get up and pumping again quickly.

Give you the power! Controlling your ability to pump water out of the ground, whether that is in the field or at home, makes you more resilient. Not relying on the grid makes you more independent. You have most of the know-how already, but our engineers are here to offer knowledge and answer questions so you can install solar pumps yourself, and have total control over your water supply.

Lifetime Rotor Replacement Guarantee

lifetime

Our brushless motors are designed to last for tens of years without maintenance. These motors (at the bottom of the pump) turn a stainless steel helical rotor inside a rubber-lined stator. Helical rotors are incredible for utilizing low power, so it makes them perfect for solar use. But these rotors are inherently the weakest point of the entire system, just like all helical pumps, especially in sand or iron-rich soil.

With RPS you won’t ever have to mail you pump off to get a factory rebuild. Replace the rotor yourself on site and save time and money. No need to cut wires either, just open up the upper pump end and swap in a new rotor and your pump will operate as it did the day you installed it.

Our Replacement Guarantee Policy means that we will replace these rotors whenever they wear for the lifetime of your pump’s motor. If you start to see a decrease in productivity out of your well over the next few years, let us know. Each kit comes equipped with a backup rotor already, but if you need that one, we will mail off another to replace it and keep you equipped with a spare at all times.
