rebuilding flojet pumps

I have three air flojet pumps on my low pressure cycles, tire cleaner, prewash and soapy brush. This is a 6 bay SS.
Are these pumps a DIY rebuild, I see kits in the catalogs and they look like they come apart easy ??? I found several old ones in the wash when I bought it so I wonder, how often they go out and are they something I can rebuild with the cheap kits compared to $100.00 apeice new. Hoping for some 101 Flojet Lessons :) Thanks.
by the way, the No Spot was at 16 tds today :) sure beats the 265 iy was at last week.

I don't rebuild Flojets. If you replace everything inside it to have a "like new" pump again, it will cost more than a new one. You can replace a problematic part here and there, but you don't end up with a pump as reliable as a new one. It's not worth the time or the chance of failure over a $75 pump to me.

I replaced all my flo jets with husky 307 pumps five years ago and have not touched them since(500,000 cars and counting, knock on wood) in my tunnel. we use them for trifoam, presoak, foamer tubes, dry aid, everything. For me in NH during the winter, flojets are so fickity to moisture I would burn through at least 4pumps through nov-march. I spent the extra money slowly and replace one by one, but just remember a flojet pumps was built to pump and mix soda not carwash chems. Think there are some better alternatives out there like a husky 307. same thing 7 gallons per minute. the price is 3 times a flojet but If you burn'em like I was then it was a no brainer

I’m only using the Flo-jet G57 pump on my Foam brush system now. I've had very good luck with Flo-jet G57 pumps, I’ve been getting upwards of 3 – 4 years on them. I’ve never repaired one. I don't have any moisture separators on my air system. Are you using the Vitron pump on the Tire/Presoak systems? I changed over my Tire Cleaner and Presoak pumps to an electric Procon pump controlled by a IDX MX-8 controller. They put out more pressure than the Flo-jet will, up to 175 psi. I’ve had the Procon set up about 15 years and I’ve had to replace the regulator once.

thanks all for the info, looks like my g57 flo jets are going ok for now but I wont bother rebuilding th eold ones at this time , sounds like a waste of my time hehe

The other disadvantage to the G-57's in santoprene or viton is they are not compatible with methanol. For those of us in northern climates, the anti-freeze detergents will tear them up. Same with products high in d-limonene (Orange Terpenes). It's a shame they don't make them with Teflon seals.

If your trying to pump a methanol Anti-Freeze soap or a D-limonene based product you want o use a G57 pump with” Kalrez” seals. Kalrez is a Teflon based product developed by DuPont.
