Style: 5.5 GPM - 60 PSI


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: 140F (60C) | Intermittent Duty | Warranty: 4 Years
  • [ 4 YEAR WARRANTY ]: Backed by SEAFLOs 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.

    • Great Performance!
I purchased this pump, to enhance my rainwater collection system. I am absolutely blown away by the performance of this tiny pump. I run garden water off of IBC totes, connected to 150 foot of water hose out to two different gardens. This pump is very quick to both start and stop on demand. The pressure is far above anything I thought, and actually more than I need. It is easy to install, connect, and use. I absolutely recommend this product across the board! I purchased a 30 watt solar panel, and have this pump connected to a deep cycle marine battery, it's great. ... show more

    • Hope it doesn't break or need repair!
I purchased 2 of these pumps, the first on 12/20/20, the second in August of 21. They seem like great pumps to start. In August, the first pump began having an issue where is cycles on and of rapidly, with no reason... no faucet open, no air in lines... I purchased the second one to replace it, intending to have the first warranty repaired. So, I would have a spare for future use if ever needed. Less than 4 months after getting the 2nd, it began having the exact same issue. I called the help-line... the guy told me he would send me a couple of new switches. (So, I must be a qualified repair technician? I work HR.) That was 3 weeks ago. I emailed the reciepts, along with the description of the issue... I get no response. I emailed, asking specifically for a response so I know I'm not being ignored... no response. I've called the help-line 6 times since the first call and can only leave a voicemail. The warranty on the first one expires in less than 10 days. I'm calling the BBB. Update, 3/4/2022: I found someone to put the switches on both pumps, put one back in service. It works, but is still cycling. The guy, Frank H. keeps telling me there must be a leak somewhere and won't honour the warranty. I've had someone crawl around under my house, look for leaks, check the power source for voltage... nothing is wrong. I'd like my money back so I can go with a different company. This pump is faulty and they won't honour their extended warranty. ... show more

This is a great little pump 12 V. I have it hooked up to a 250 amp battery on a trickle charge solar panel. And I never worry about my water.If aren't you with these folks is unmaturable if I have a?

    • Awesome pump
I've had several pumps like this through the years. This one is quiet, strong and provides a lot of water pressure for my boat deck wash system.

    • Definate QC issues, but don't give up on it
I'm using this as a transfer pump for my RV to transfer water from the 35 gallon transport tank to the RV fresh water tank. (it's easier than moving the RV to the water spout) Removed the pump from the box and installed - piping, electrical, etc. Hey, it's brand new, what could go wrong.... Apply power.... and.... nothing. Fuse, check. Electrical connections, check. I jumped out the pressure switch in case that was faulty, nothing. Checked the current draw with an ammeter, zero amps. The pump motor was DOA. I did a return/replace. New pump arrived in 2 days (thank you Amazon delivery crew). I took it out of the box and immediately tested it. It's working. NOW it will get installed. ---- Like any product, you're going to have a few duds off of the production line, but looking at the other reviews, it seems that SeaFlo may have a higher failure rate for this pump than what would be considered "normal". Either that, or people only post a review when something isn't right. How many times have you called the service department for anything to tell them that they make a great, trouble free product? ... show more

    • Extremely Quiet.
I cannot speak to the multitude of applications and mounting options...only my own. I replaced an increasingly noisy Pentair variable speed pump with this Seaflo Series 55 in a Country Coach Magna. No changes to plumbing were made except having to adapt the inlet and outlet hoses to mate properly with the pump itself. While comparing the new pump to an obviously failing Pentair would be unfair; I can confirm it is quieter than the later even when it was new....by a LOT.....So much so that the only sound heard inside the coach is a very,very muted hum. No vibrations are felt at all. With water flowing into a sink; there is absolutely no sign the pump is running at all. I do have the benefit of a fairly large expansion tank which I adjusted to 42psi bladder pressure per the Seaflo instructions. To this, some portion of the low noise level must be attributed. There are also soft hoses rather than rigid pipe on the plumbing runs that mate to the pump. No doubt, this helps a bit more. So, if quiet is your goal; this pump along with soft inlet and outlet hoses and an expansion tank set to 42psi, you should find yourself a happy camper. I will update the 4 star rating to 5 if it proves reliable. ... show more
