RPS Steel Pro 18RPS07-S 4" Submersible Pump End | Stainless Steel Impeller | 16-21 GPM

The RPS Steel Pro 18RPS07-S subermsible water pump brings full 304 stainless steel construction — outer body and impellers — to a price point that everyday families and working operations can actually afford. That used to be an industrial luxury. Not anymore. Why does stainless steel impeller material matter? Because your well water isn't just water. Sand, dissolved minerals and hard water deposits can all take a toll on components over time. Steel impellers are the best at resisting abrasion and shruging off mineral buildup— meaning more consistent flow, less efficiency loss, and fewer surprise failures at the worst possible moments. The 18RPS07-S delivers 16-21 GPM with up to 150 feet of total head — built for residential wells, ranch water systems, farm irrigation, and industrial applications where you can't afford downtime. It's also the go-to upgrade for sandy wells. Pair with a pressure tank - but make sure to size with an RPS Pump Specilaist first (855) 560-5670. NSF Drinking Water Certified and UL Listed — built to the highest standards so the water reaching your family, your livestock, and your crops is clean and safe. No cutting corners where it counts. Built for wells, tanks, and ponds. Pairs best with a 3/4 HP motor end — RPS motor ends sold separately in 110V or 220V.
