Transfer Pump for CW chemicals

[cwguy.com]

Well I finally built my own pressurized 55 gallon drum transfer device..... thanks to Mike and 2Biz's comments. Except I did not use any regulator or gauges.... not really sure if this is how 2Biz made his either? The air filling the drum is at 100 psi.... took a little over 30 seconds.

This really worked good.... I always hated using hand pumps and setting up air pumps was always time consuming (I thought).

After piecing this together.... I thought if I purchased all these parts new I could have purchased any pump I wanted.

How big of a mess did you end up making before you realized there was no valve you could close to the line going to the jug?

The chemical was a tri-foam ultra concentrate.... I thought it was going to foam worse actually.

Yes.... I should have cut it off earlier. I did not install a valve because I do not want to keep the drum under pressure. I do see how a valve in an emergency might be helpful though. But this was really not that bad.... I have seen worse with other methods. I should have used a 15 gallon bucket for the first time I used this method though.

I think this will be a lot cleaner method.... probably better to run a lower psi. But I would have had to find one of my spare regulators. So I tried this.... just sharing what happened.

Eric,

Just a thought ... you may want to get a 3 way ball valve for the air side that meets the low specs needed. You may be surprised at how reasonable those kind of valves have become. A pop of valve could also make sense ... just in case some serious distraction occurs while you are in the middle of pressurizing. It is a bit like siphoning momentum; so if the liquid is thin enough it might keep flowing even with no air pressure .... something to possibly consider.

I would have just used an air line quick disconnect, but keep in mind the siphon properties will still keep you from unhooking the air line and walking away.

If the hose reaches the bottom of the bucket you're filling it shouldn't foam at all.

I thought the chemical would siphon also.... But this chemical may be to thick somehow? Or I was pushing out to much air?

The outlet hoses are also all the way to the bottom of both drums.

The ball valve was not run wide open either.

A three way valve and a valve on the outlet side are good ideas. But again there was no siphoning happening.... Which is why there was really not a huge mess like suggested.
