SEAFLO 55-Series Diaphragm Pump - 12V DC, 5.5 GPM, 60 PSI with Heavy Duty Pressure Switch | Self-Priming, Quiet Operation, 4-Year Warranty | Ideal for RV, Marine, and Off-Grid Water Systems

Great pump, come with filter and ready to install with instructions, perfectly and securely boxed to prevent damage. Very satisfied!

I feel that this this pump moves a little too much volume for my 5th wheel. I was previously running a 42 series Seaflo, which was very quiet with less cycling. I upgraded to this one to experiment with the additional volume that this supplies. Showers are definitely more powerful, but even after adjusting the bypass it still cycles a lot on low flow feeds like my RO filter (with a booster pump to insure RO gets enough pressure under all conditions). RO pressure meter fluctuates a lot with this pump.Possibly could be rectified with a accumulator tank to smooth out the cycling and absorb some of the surge from the larger flow. Ultimately I'll probably just revert to the 42 series and keep this one as the spare.No complaint against the actual pump, other than not a excellent match for my application. Seems like a very nice pump.

Seaflo pumps are garbage. Worse than that they have horrible customer service. I purchased 1and it lasted 3months and it failed.Called customer service and you can't talk to anyone.Made the mistake of buying a second one and that one didn't last 1 month.And I am still waiting for some kind of response on the first one. BAD BAD Business practices.

Good product

It is working very well after many months pumping water to my off grid home... and many tens of 1000s of gallons to irrigate about 10 trees on the property. I pump about 20,000 to 25,000 gallons per month. I bypassed the onboard pressure circuit switch within a week. Those never last on these RV style pumps for my application. I use a simple Square-D pump switch for that. It is the pump itself I need to push water at a reasonable rate and pressure for some time. I expect a few years of constant use from this pump. Motor and pump seem very well built. And very quiet when compared to other name brands I have been using for 7 years on this home.

I purchased this pump when the pump on my Yamaha 255 FSH failed. This was the salt water wash down pump for my boat. Living in Central Florida were in salt water all the time, so I hope this pump holds up much better than the original factory installed pump which only lasted 2 years. Only time will tell.

I have tried 3 pumps from 3 manufactures in 3 months. All has failed. First 2 failed due to actual pump motors. This pump motor is the best so far and has great pressure. But there is a major flaw with this item. It is the pressure switch. If you look at other feedbacks there has been many pressure switch failures. If pressure switch was high quality, I would give the item a 5 star. But very poor connection and switch overheating that will also cause the actual switch to burn out, I don't recommend it for the average buyer. First one that came and lasted one day and the connection went bad. It was clear to me that the switch had to be fixed. Because the pump motor is such a high quality, I purchased a replacement and installed a solenoid relay so that the poor connection and poor relay will not fail. If you don't know how to install solenoid relay, don't buy this product. It will fail very quickly.

I have a used 2016 G.D. Reflection Rv. When I first turned on the water pump, I knew that id wasnt staying. So looking at water pumps and give better flow, I saw this bad boy. OH yea GREAT buy. It might not last but its 100% better than stock. Way more quiet and vibration is reduce a ton. I also see some of it is from the pipino moving so Im going to insulate that in hopes of helping the noise. But this bad boy runs Nice. I havent even put in the expansion tank yet but did install valves to make it easy to do.
