The RPS 400N ("Narrow") was new to the RPS fleet last year. Our first 2018 model was popular, we improved on it over the winter and are excited for the release of the 2019 Model.

Yes, it fits 2.5" and 3" casings. Yes, it can sneak in next to an existing pump/pipe in a 6" casing to act as a backup redundant pump, or if a pump is stuck down in the well. Yes, it can fit in windmill wells that could never take a submersible pump before! 

Like our 3" pumps it features a helical rotor. It features maximum head of 150 feet and flow rates up to 5 gallons per minute. 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.

The maximum power point tracker includes a low water sensor to ensure the pump does not run dry and optional tank sensor to ensure the storage container does not overflow. Included in the complete system are four (4) 100-watt mono crystalline silicon solar panels. These panels feature tempered glass for impact resistance in severe weather conditions. Each panel has one male and one female MC4 electrical connectors for easy waterproof hookup. We provide parallel pigtails as necessary to hookup panels, to eliminate the guesswork.
