1/2' Versa-Matic AODD

[Jeff]

Last year I bought a bolted  model 1/2" Versa-Matic poly pump. I had posted at one point last year about the bolts coming loose in a short period of time,..I do remember it leaking on the very first job I used it on. So,..I tightened the bolts to proper torque specs, used lock washers and red Loctite. Running at 85 PSI it held for awhile,..now are loose again and will not seat down the top manifold to the body of the pump,..and is leaking from the flanges where the two pieces mate together. Doesn't leak like a spray,. but trickles with every "pump". stroke.  Probably got a lemon but will be my last Versa-Matic pump I think,..and possibly the last bolted model. 

As far as the pump itself,  it works well and doesn't stall,.but this leaking issue is a pain. Most likely going to try and plastic weld it as soon as my new pump gets here and I get it replaced. If I ruin it,.so be it,..don't much care,..I hate leaks. Thought of pulling it apart and using some sort of sealant between the flanges to help the seal,..I don't know though. Any suggestions on how to fix this PITA pump? Not gonna put any Versa-Matic rebuild parts in it. It's only a year old,.and if the ones in it are worn,..it will be considered a backup, and fixed the best I can.

I ordered an All-Flo like I had before that lasted 5 years and worked very well until it froze and broke.  Stalled now and then,.but no big deal,..and should work well with my current air drying system I have been using with the Versa-Matic.

*Point of the post was to give my experiences with the Versa-Matic model pump I bought.

silicone sealant should solve the problem.

[Jeff]

Thanks Gary,..I may give that a shot before melting it together.

It is probably the seat gaskets. They are fairly thin. 99x out of 100 if I have a manifold that is leaking, just change the seals and no more leaking. Send me the complete model number on the pump so I can look up what seat seal material you have. The SH does effect some of them and swapping them with a more resistant material may do the trick...or just get a few spares and swap them out. 

If you decide to dump it...I buy used pumps. 

[Jeff]

Thanks Kevin,..the model number is:  E5PP6X669A-G 1/2" ,....You're probably correct, it is likely the seat gasket(s).  Are the seat gaskets available as a separate piece, or do they come in a rebuild kit?

I wouldn't mind putting a LITTLE money into this pump considering it's only about a year old. Yes,..I'd be interested in the better materials. I know the body is poly and diaphragms are santoprene. 

Thanks for taking the time,

Jeff

Okay...Poly body, Santoprene diaphragms and yup, you have E510XL seals in Santoprene. Upgrade it to E510VT seals which are Viton, KE521 Kynar Seats and V111VT Ball valves.

Should be pretty cheap from Versamatic.

Thanks Kevin, It looks like these are basic o-rings?  They seem inexpensive enough,.  Also,..are these 0-rings in a typical size,...that I could maybe buy local?  I realize the viton is better, and if I order them I will order the viton,..but just to see if the issue is resolved I may install basic o-rings.

*I will take it apart as soon as I get the other pump installed. The Versa-Matic is still working well,..and didn't even leak yesterday. I will be glad to have a spare  either way,.because even a leaking spare is better than no spare.

Thanks Again,

Jeff

They are not a typical size and they are usually shaped to fit into a groove created between the seat and the manifold. Putting another seal in there is fine but chances are they won't last as long or seal as well. 

[Jeff]

Thanks Kevin,..I will be calling Versa-Matic to check on the parts I need. My new pump will be here today,..so I will be able to take the other apart and have a look at it.
