    George,

    From what I could find on the Procon site, it appears that he ump is a food-grade beverage carbonator pump. It is a rotary vane (which means positive displacement) pump. There is no "regulator" as such, but there is a relief valve that will pass the over-pressure discharge through the relief valve body back to the inlet side of the pump, as is common with all positive displacement pumps.

    In a positive displacement pump, the discharge CANNOT be blocked without some arrangement for the discharge to be relieved. If the discharge is blocke, the pump WILL stop unless something elese breaks to relieve the pressure.

    The pump comes in models that are rated for potable water only, and for chemicals. The potable water pump model has seals which will be harmed by additives, like ethelyne glycol, or some other algae inhibitor.

    I'm not sure I'd use one of these for a cooler.

      Thanks, I did take mine apart to see how it works and I think it will do what I need. the spring on the relief valve can be regulated to dump more or less pressure pack to the inputside, worse case the spring can be changed to a weaker one but the one I have is supposed to regulate from 50 to 150 psi and I need it to be 50 psi so thats good. I plan on using only demineralized water in it so the seals should be fine. I got some fittings with barbed connectors and some tygon (250 psi rated) and will hook the pressure guage and my friends #20 torch and see what I can see. All the coolers, Miller, Hobart, Binzel, whatever use the procon pump so I am guessing they are using the chemical rated one.

      Worst case I can bleed off some pressure back to the tank right after it exits the output side if I have to.

        I hooked my 20 series to the garden hose today, i get exactly 1 qt /min flow with it. i was cooking some steel at 200 amps and the torch was cool to the touch! i already love it. The procon pump is positive displacement so you cannot dead end it! the motor or a hose will blow. i actually looked at it today and thouht there was an inlet restrictor but since there was a spring in there i am assumong it is an adjustable pressure regulator. Problem solved as far as that goes, good too since its cheaper and more compact. so long as you restrict the output you will be able to set the pressure without the torch attached and it won't change if the torch changes. I would incorporate a pressure switch though so you know water is flowing.

          The inlet restricter is acutally a pressure relief valve that pushes against the spring loaded piston from the outlet side to dump excess pressure back to the inlet side. I am going to do some tests today to find out if the output pressure (with a #20 torch connected) can be adjusted by backing off the spring pressure. 1-1.6 qt/min is what you need I think, at least thats what the Miller coolers are rated at, funny thing is that the 2500SS cooler and the Binzel cooler that Arc-Zone sells rate their coolers at 1.6 & 1.7 gal/min using the same pumps and psi I did notice that some of the older Miller coolers had a bleed valve in the output port just after the pump set to
          45 psi but they don't list the valve in the parts list.

            George,

            Well, if that's the pump they put in the big buck coolers, I guess it's the right pump, huh? Good luck. Guess I better start acquiring some of these goodies myself!

              Seems like quite a hassle to build a pump, heck for a hundred bucks and shipping I'll send you a working used coolmate 1.

                  I have the testing done and it works as expected in that I was able to vary the output psi with the torch connected by changing the spring load on the bypass. I can vary it from 35 to 100+ psi, I set it to 50 psi and checked the flow, at this setting it will pass 1 qt/min of water which is about right compared with the coolers for sale. Now I need to wait until the radiator, Fan, surface mount psi guage, & lighted power switch get here....then I need to find a tank (probably a 2 gal poly spare gas tank), then I can make a wrapper and put the thing togeather. Attached are pictures of the Mickey Mouse setup I used to setup and check the pump.

                    Then we'd spend even more time trying to make it fit under our welders. I'll have less than 100 into mine and 4x the radiator of a coolmate 4 when I'm done.

                      Looks good Sundown! Mine came with a stainless steel tank but i would like to make my own. I want it as compact as possible.

                      Does anybody know the type of fittings used for the torch and gas lines?? I don't know what there called so i can't seem to find them! I would like to mount a pressure and return on a panel on the front of the cooler with quick connects. Same for gas in on the front of the dynasty.

                      I'm hoping to mock up the tank this week out of oaktag. Then i'll attempt to transfer it to metal. I'll post pics of any progress i might make.

                        I am interested to see what you come up with, I'm stuck on mine until Surplus sends me the rest of my stuff. As for dis-connects try this link.....

                        I think the connectors are the "5/8" x 18LH "B" Style Female", should be able to get them at a welding dealer I hope.

                          Yep, 5/8-18 LH Female is right. Mine were 3 bucks a pop at the welding shop.

                            Use that tig to weld up a stainless tank. HMMM This could be like machine work. Use the tools to make maor tools so they can be used to make still more tools. Guess the fun never stops. ha

                              Hmmmm, if I did that I could make it the shape I wanted instead of having to settle for whatever I could get. On the other hand I like the idea of having a plastic tank, and there must be a reason why the big makers are going to plastic tanks inside of SS box's.

                                Any shape you want? You're not in the market for an english wheel are you? LOL I wasn't aware the stainless tanks had a plastic liner.
