SEAFLO41 Series Water Pressure Diaphragm Pump - 12V, 4.5 GPM, 40 PSI, Self Priming, Smart Pressure Switch, UL & CSA Certified, for RV, Caravan, Off-Grid, Marine, and Industrial Use - 4 Year Warranty!

Used it to replace a pump twice it's physical size on my 36' Trojan yacht. The original pump was leaking, and blowing the breaker all the time. This pump is super quiet, got primed on its own, built pressure on its own, and hasn't tripped the breaker once. My only wish is the inlet and outlet came with 5/8" hose nipples. I had to reduce my 5/8 hoses down to 1/2", which I know reduces flow., but will deal with it.

I bought 3 Seaflo products; 2 pumps and 1 float, EVERYTHING BREAK A VERY SHORT TIME, MORE OR LESS A MONTH. They are not well made and very fragile. The pump before this one blows my fresh water system in my boat, my retractable hose (the one who shrinks) blow, 800$ damage. The Pressure switch become crazy and don’t stop. This one makes my lights blinking while it operated. Finally, the pumps stop completely.Even if the pump was reported broken 32 days after I bought the pump on Amazon, this seller offer me to replace the pump, but when I tell him I was in the Bahamas, I don’t hear from him anymore even after 3 emails. N news. No suggestion but their pump is not good but my money was good.Good luck!

This pump was quick to connect, pressurized the system immediately, and has made all my faucets work great! Just note, if you have water restricters, the pump cycles on and off because it represurizes so quick that the faucet cannot let enough out which makes it pulsate which sometimes throws the breaker. If it can just turn on and pump freely, without water restriction, you get incredible water pressure. totally awesome bang for the buck here!!!

This unit is a little to powerful for my application. It is a great product, well constructed. I should rate this product as a 5 star because it is a good deal. I am not sending it back because I feel that I will find a use for it in the future.

The connectors were a little smaller than the one I was replacing, but it works great. I use this as a combination bait well pump and wash down. The connectors made it a little easier during the install. (quick connect)

great value. planning to buy a second for back up after a few months of using this one. be advised, though it looks just like a Jabsco pump (and it might vaery well be), this is not as well sealed pump/motor/pressure switched pump as their $125-200 'marine' models so think carefully where you are going to put it if corrosion will be a problem in your application. the 4 legs provide good support and isolation but do not match Jabsco's marine pump mounting hole patterns. the rubber legs slide into mating slots but removing 2 of them exposes the innards of the unit so not likely to be extremely 'splash' resistant for moisture getting where it was not intended to be. the pump is quite well made and is as quiet at the Jabsco pump it is replacing. I am assuming Jabsco replacement parts will fit but I seem to always wear out the motors so end up getting a new pump. Be advised the pressure switch is not at all splash resistant so I am likely to replace it with the marine component to better protect the electrical connections.

I recently purchased this pump for a 30 gallon sprayer to spray weed killer,(round-up). This is the second one I have purchased in about 2 years. My old pump started cutting off after activating the sprayer for about 90 seconds. It seems that the thermal cutoff switch was cutting it off in a very short time maybe after only spraying about 1/2 gallon .This is why I purchased the new replacement pump.After installing the new pump, I had the same problem, it cuts off after about 60 to 90 seconds of operationYou then have to wait about 2 minutes for it to cool down and reset.I am very disappointed in the pumps, when I bought the first one it worked good for the whole season. I thought I had found the perfect pump for my spray rig,( wrong),After recommending this to 4 of my friends last year and them purchasing pumps, I feel pretty bad for my advising them to buy this pump. This pump won't run long enough to fill a 2 gallon container without tripping the thermal cutoff switch. Don't buy one if you intend to run it for over 90 seconds at a time.

Good replacement for our sailboat. Easy to install and great functionality. It came with 3 different connectors, but only one of each kind. So I had to use a different one for the inlet and for the exit. I really needed two identical ones, but it's not like it's the end of the world or anything.

For the price it is a really great little pump. For double the price it is a great little pump. I have one that I use in my distillery (not the recommended use) and it works great. As long as you have the screen installed on the inlet the pump will keep pumping for ages. Diaphragm by their nature don't love solids so with the screen this puppy works like a hot damn. Strong pump. Only challenge I found was finding a power supply that was reasonably priced and wouldn't burn out while running the pump. Went to my local electronic supply shop and bought a power supply that was properly rated and a couple bucks more than the cheapest version and it has worked great for over a year now. Purchased a second one as a backup because I like it so much. Pump does get a bit warm but nothing crazy even after a couple hours of continuous pumping.

Ne fonctionne plus après seulement quelques mois. Très déçu et aucun retour de la par d'Amazon ni du vendeur.

The product is good but it takes a lot of amperage

The pump works extremely well and is very quite. I would have preferred threaded connections on both the inlet and outlet side of the pump. If the parts furnished were to break ,you won't find replacements To readily at any plumbing supply house.

Works great
