SEAFLO 55 Series 12V RV Water Pump 5.5 GPM 60 PSI Diaphragm

SEAFLO 55 Series 12V RV Water Pump 5.5 GPM 60 PSI Diaphragm Pump Heavy Duty Pressure Switch Built In Bypass Self Priming Quiet High Flow RV Marine Off Grid Freshwater System 4-Year Warranty
- [ SPECIFICATIONS ]: Model: SFDP1-055-060-55 | Voltage: 12V DC | Flow Rate: 5.5 GPM (20.8 LPM) | Shut Off Pressure: 60 PSI (4.2 BAR) | Suction Lift: 9 ft (2.7 m) | Max Draw: 17A | Ports: 1/2 in MNPT Threaded | Materials: EPDM valves Santoprene diaphragm | Max Temp: 140°F (60°C) | Intermittent Duty | Warranty: 4 Years
- [ 4 YEAR WARRANTY ]: Backed by SEAFLO’s 4 Year Limited Warranty, this pump is built for long term reliability and peace of mind in demanding freshwater systems. Designed for daily use in RVs, boats, cabins, and off grid installations, it provides dependable performance where consistent water delivery is essential for comfort and functionality.
- [BUILT TO NSF UL Standards FOR RV POTABLE WATER ]: Built to NSF/ANSI/CAN 61 & 372 (Potable Water Safety), NSF 24 (RV Plumbing), and UL 778 (Motor-Operated Water Pumps) Safe for drinking water and compliant with RV and marine plumbing standards across North America.
- [ HIGH FLOW 5 CHAMBER DESIGN ]: Advanced five chamber diaphragm construction delivers strong output up to 5.5 GPM while reducing rapid cycling compared to smaller pumps. This allows simultaneous use of multiple fixtures such as showers, faucets, and washdown hoses while maintaining stable pressure and smoother water delivery.
- [ HEAVY DUTY PRESSURE SWITCH WITH BYPASS ]: Integrated smart pressure switch automatically starts and stops the pump based on water demand, while the built in bypass stabilizes pressure and reduces frequent on off cycling. This improves system efficiency, extends service life, and delivers more consistent performance across varying flow conditions.
- [ SELF PRIMING RUN DRY CAPABLE ]: Capable of self priming up to 9 ft, the pump can be mounted above the water source without losing performance. Run dry capability protects internal components during temporary water shortages or tank depletion, making it highly reliable for mobile systems and remote installations.
- [ QUIET LOW VIBRATION OPERATION ]: A semi rigid rubber mounting base isolates vibration and reduces operating noise, making the pump suitable for enclosed compartments such as RV cabinets or boat lockers. This quieter performance improves onboard comfort while still delivering the high flow output required for everyday use.
- [ DURABLE MATERIALS FOR HARSH USE ]: Constructed with corrosion resistant components including EPDM valves and a Santoprene diaphragm, the pump withstands demanding freshwater and saltwater environments. These materials provide strong sealing performance, abrasion resistance, and long service life in marine and mobile water systems.
- [ INCLUDES INSTALLATION ESSENTIALS ]: Supplied with two 1/2 inch barbed hose adaptors, a 50 mesh inlet strainer, and installation instructions to simplify setup. Combined with standard threaded ports and pre wired leads, the pump is ready for straightforward integration into compatible RV, marine, or off grid plumbing systems.
