RPS Steel Pro 40RPS50-S 4" Submersible Pump End | Stainless Steel Impeller | 14-53 GPM

The RPS Steel Pro 40RPS50-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 40RPS50-S delivers 14-53 GPM with up to 200 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.
