My previous on demand water pump died because of the pressure switch. I had it about two years. This time I was willing to pay more for hopefully a better pump. Time will tell. I’ve only had it a couple weeks. It has a 4 year warranty which I registered on line. (Very simple) installation was very straightforward. No surprises. The two things I liked immediately was, just how quiet it was. The old one you could hear throughout the boat. This one can barely hear in the bathroom on the other side of the bulkhead it’s mounted on. The second one is the pressure. After living most of my life on a boat I just got use to slightly low water pressure. This one has house water pressure or slightly more, even though it’s rated the same as my old one. Reliability I don’t know yet. If I have problems I’ll update it. Review: Delivers More Lift Than 9-Feet - I have this pump mounted to a wood frame to pump water from my home's well to irrigate my potatoes and black raspberries. When I can babysit it, I connect it to a 12-volt automotive battery. This battery is recharged by a 100W Renogy solar panel, controlled by a small charge controller. The specs of this pump said the maximum head lift is 9-feet, so I cut the siphon (inlet) tubing 9-feet long. The water level in my well is about 9-feet below ground, so it was barely long enough to reach. I added another 5-feet of tube and found that it pumps water and mostly maintains a prime, although sometimes it'll lose the prime and stop pumping. So far, I'm pleased with its performance. ## Features - [ 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. ## Technical Specifications | Specification | Value | |---------------|-------| | Brand | SEAFLO | | Color | White | | EU Spare Part Availability Duration | 4 years | | Flow Rate | 5.5 gpm | | Item Dimensions L x W x H | 8.5"L x 5.75"W x 5.16"H | | Item Weight | 6.1 pounds | | Material | EPDM, Santoprene | | Material Type | EPDM, Santoprene | | Maximum Lifting Height | 9 feet | | Power Source | 12V DC | | Product Dimensions | 8.5"L x 5.75"W x 5.16"H | | Product Style | 5.5 GPM - 60 PSI | | Style | 5.5 GPM - 60 PSI | ## Product Details - **Brand:** SEAFLO - **Color:** White - **Item Weight:** 6.1 Pounds - **Material:** EPDM, Santoprene - **Maximum Flow Rate:** 5.5 Gallons Per Minute - **Maximum Lifting Height:** 9 Feet - **Power Source:** 12V DC - **Product Dimensions:** 8.5"L x 5.75"W x 5.16"H - **Style:** 5.5 GPM - 60 PSI - **Voltage:** 12 Volts (DC) ## Images ![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 - Image 1](https://m.media-amazon.com/images/I/71S3VtoWTML.jpg) ## Available Options This product comes in different **Style** options. ## Questions & Answers **Q: Why does amazon list this as 55 series but everything on the box is showing 51 series? what it it?** A: Company sent me a 51-series in a 55-series box **Q: Will this hold up in salt water as a washdown pump, or does seaflow make a different product for saltwater use?** A: if your going to use in salt water, flush it out with fresh water when done. **Q: Will this pump hold up bleaching water??** A: probably not as a chemical add pump. Should be fine with small concentration if you add bleach to holding tank. **Q: Will this pump work with hot water?** A: I would contact the manufacturer. A lot of pumps are rated to handle a certain range of water temperatures. Some pumps will use the water as a coolant, where others have high temp seals to deal with hot water. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Quite and powerful! *by W***I on May 23, 2026* I’m a full time livaboard on a 44 foot trawler.
