Just a follow up on this,..the air cooler I rigged in,.(50" of air hose immersed in water),....has made a huge difference in my pumps performance in regards to stalling,..basically non-existent. Two stalls since this design change, WD-40 each time and the problem was resolved with lasting. 

Not to mention the visible difference I see in the water trap. Before the trap would barely collect any water, because the water was passing right through the trap as VAPOR,...now when I look at the trap it is usually half full or more. So that tells me the cooling hose is working. 

*I created another problem for myself as well with trying to make a nice neat design. I designed my top draw with a bulkhead. As we all know these pumps pulsate. My pump started spitting air every few seconds,..Like and explosion of mist in front of your face,Ha,Ha,..anyhow,...turned out the pulsating was cracking the fitting,.I tried another one and in a short period of time did it again,...So now I have a more forgiving design that seems to be working.

 

** The 3/8" All-Flo I had used before was a better "non-stalling" pump than the 1/2" Versa-Matic I use now,..maybe due to design or due to air requirements??

I'm very happy with the 1/2" Versa-Matic,..but,..there is an issue with these that needs to be addressed. The bolted design I like,..but the bolts coming loose I don't like,..and they come loose every now and then and spray SH all over everything. I've tightened them a few times and now my plan is to Red Loctite them and torque to proper specs.

 It is because of your air compressor Jeff. The little 3/8 all flow was more happy with that small compressor, because it does not require as much air. Once you move up to a 8 to 12 HP Compressor, much of your stalling issues will go away.

I should have clarified the statement of the All-Flo being a better non stalling pump than the Versa-Matic. I should have said that::It's a better non stalling pump "Out Of The Box And Slapped Inline"......After the use of the cooling hose the Versa-Matic is essentially non-stalling,...only two times since I put it in use.

@Marcus,..The cooling hose is a one time purchase and works very well at it's intended purpose,..cooling the air so the water trap can function properly. The desiccant type need the material replaced every so often, especially in high humidity. Not a big deal I guess,..would just rather not have to.

Also,..I don't rebuild anything,..I just buy new,..as the cost to do so is so VERY minimal compared to the profit made. Just not worth it to me.


@Chris,..Yea Chris,..I figured that was most likely it,..but as I said, with the more proper air getting to the pump the stalling has essentially gone away,..so not a big deal at this point.

 Jeff, don't feel bad about your Versa Matic needing to have the bolts tightened, every now and then. Our Kynar Yamada roof cleaning pumps are like that too. Before I learned, I have snapped plenty of pumps, by overtight.
