KolerFlo KF55-12 51-Series RV Water Pump 12V Fresh Water Pump for RV, with Heavy Duty Pressure Switch & Strainer

The Kolerflo 12V RV Water Pump is designed for high output, long-term durability, and smooth performance across a wide range of water systems. Its upgraded 5-chamber diaphragm provides superior anti-backflow control and stable pressure, delivering up to 7 GPM with an adjustable pressure switch that can reach 70 PSI. This makes it ideal for supplying steady water flow to RV showers, sinks, sprayers, and other fixtures.

Built with a thicker copper motor and NSK dual ball bearings, the pump offers improved heat dissipation, longer lifespan, and reliable operation during extended use. Its strong self-priming capability—up to 10 ft vertically or 155 ft horizontally—ensures dependable water delivery even in off-grid or remote setups.

Installation is straightforward with 1/2” NPT ports, included barbed hose adapters, and a stainless steel 50-mesh inlet filter that prevents debris from entering the system. The pump operates quietly at under 65 dB and includes multiple safety features such as thermal protection, dry-run protection, and overpressure safeguards.

With CE certification, an IP68 waterproof rating, and an operating temperature range from 5°F to 140°F, this pump is built to handle the demands of RVs, boats, agricultural sprayers, irrigation systems, and other 12V water applications.
