shur flo or flo jet pump problem

[floorguy]

I dont remember which, and to lazy to go look...

its a 100 psi pump...

anyway it started cutting out, and you would have to smack the machine to get it going (this is my prespray machine)

So i finally took it out...and apart....cleaned it out, put a little lube on it, test...test...test again, it works fine....out of the machine and in.....


Now its cutting out again...this time more....

I had one do it before and it was the Carbon brushes worn down and had build up...cleaned it and worked fine...but they were WAY worn.....

Near as i can tell not a problem here...

when it pumps its still strong.....it just needs a good whack...and getting worse

WTF is going on here??

If you spent more then 15 minutes trying to fix it it would have been cheaper to replace it....just saying...

"Whack" it harder....then what ever is sticking or lose will finally come free or break and then you will know what is wrong........then you can finally stop wasting your time with it and replace it and get it over with....pretty sure that's the road your heading down anyway........

I found that the first thing to go bad is the micro switch. Cheap and easy to replace.

X2 I wish I wouldn't have thrown away as many perfectly good pumps as I have..

I would think that Doug is smart enough to check the switch.....I am thinking the armature is sticking.....

Doug;

Our experience has shown that this is usually the "pressure switch assembly".

Chemical swelling of elastomers in the switch assembly can cause this condition.

We have the ShurFlo parts available:

Doug is hard headed but not completely stupid I'm sure he already replaced the switch right Doug?

 

[floorguy]

uhhhh switch what switch


as i tell my mechanic.....my brain isnt always there for trouble shooting...thats why i ask you guys.....

just like this....cleaned it all out...but didnt even think about the switch....

because i do believe the last 1 or 2 on there may not have had one.....unless it was built in???

Doug;

On this page you can see the square switch assembly . . .

and the side view of the pump with the switch & red wire.
