You're looking at a pump end that's keeping water flowing across thousands of American farms, ranches, and homesteads. The RPS Core Series 10RPS50 is a 6-18 GPM submersible water pump end built for everyday reliability in household wells, agricultural operations, irrigation systems, and even industrial use. Rated up to 800 feet of total head and built for continuoius duty, it easily handles the demands that rural water systems require, day in and day out. Pair with a pressure tank - but make sure to size with an RPS Pump Specilaist first (855) 560-5670. Constructed with a 304 stainless steel outer body and engineered composite impellers, the Core Series gives you serious durability at a price point that makes sense. 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. Works great pumping from wells, tanks, or ponds. Pairs best with a 5 HP motor end — RPS motor ends are sold separately, available in 110V or 220V. Also fully compatible with motors from Franklin Electric, Goulds, Grundfos, Pentair, and Berkley, so it drops right into your existing setup. If you're setting up a new well system, replacing a worn-out pump end, or just want something that'll run for years without giving you trouble, the Core Series is where most folks start — and where a lot of them stay.
