Ha ha you know I did think about it but thought that was ott. Not sure yet I don't have that much time to spend on little details at the mo. The fact it's up and running is a bonus lol.

Flow rate is on the high side. It's said that for best cooling results 1-2 lpm at the return back to your tank is the optimum. I timed this one into a measuring jug for 30 seconds with a 4 Mtr torch and got 900ml (1.8 lpm) with 8 Mtr line total.

Only if you use the dedicated pumps designed for it. I've built on shower and caravan pumps which can be picked up used for a lot less. I pulled this pump out of a cooler that supposedly didn't work. Further investigation showed it was simply blocked so I got it very cheap. Stripped it and built a better one.

There is also the option of fitting a T piece to the outgoing with a line going back to the tank and a valve. So you can control how much flow goes through the torch but not putting pressure on the pump. This way if the pump is overkill you can control exactly how much flow you want down the torch line. I've done this with a procon set up. Works fantastic. You could use a 150psi 50lpm pump this way and still get 50psi 2 LPM at the torch and the unwanted pressure ends up back in the tank. Pump doesn't know no different.

It's very hard to see but on the out going of this I've T'd off.
The line to the tank has a tap. The more I open the tap the less pressure I send down the torch line. Full control over pressure and flow rates without damaging pumps using pressure screws etc. If I want more pressure on the torch I'll close the valve slightly sending it down the torch line. Was my most effective build to date. Could set it perfectly

Pro-Con type pumps used on beer coolers seem to be easily available, and cheaper than anything welder related.

They are expensive when you don't have a motor to mount on. I doubt you'd get a good procon set up with motor for less than £100-120.

Over kill is good. It's easily sorted as I say above. Under kill is a problem but by the sound of it your not gonna be suffering that. Tag me in the new thread I'll be reading with interest.I've just found a manual, and it details just using a gate valve on the outlet to control flow - pump still maintains 100% duty.
I'll cobble up some adaptors for the 1" bsp connections and start a new thread

Got one complete with motor last year Ebay £25. Parts are available for pumps as well. A used beer cooler will provide almost all the parts needed for welding cooler, and might even be able to be used alone if looks not a problem.

Well just cos some plonker sold you one well under value doesn't mean they are cheap. A new procon pump and motor (basic low pressure one) will set you back easy £150 and used they still go for over £100. Don't believe me??? Link me to one that's cheap!!!!!
Strange though you always seem to get hold of stuff cheaper than most have ever seen it. Are you sure your not telling a few porkies. Links and pics seem to be very few and far between.

Guy had quite a few Pro-Con pumps and motors to sell.........all used and I would imagine came out of scrapped vending machines, or maybe beer coolers?
Beer cooler I would guess would be pretty easy to convert for welding use, or if not they contain nearly all the parts needed to make a cooler. Used ones seem to go for around £100-120 mark, and seem to get listed quite often.
Stainless steel gastronorm is ideal for tank, and pump and heat exchanger can be mounted on the removable lid, then all thats needed is a cover of some sort, and you have a usable cooler for hopefully less than £200. Not my idea though, think I saw build on Welding Web forum.............
This is the pro version of the DIY build outlined above: http://stores.ae-welding-industrial...-sentry-ae-3500ss-free-shipping-to-48-states/

How does this compare to the home made ones, it seems quite small.

Big. Mines 300x330x150.
If size is not a prob it'll be up to the job. I think the RTECH one is rated to 600 amps. Big tank big exchanger lots of fans Mine is a 3 ltr capacity. With a 2 mtr long exchanger and a single fan. I would say continuous use mine will happily cover the torch rating (250 amps ac at 100%). I wouldn't want to push it more than that incase it starts warming the water up.

Say someone had a small pressure washer lying around, could the pump with motor be used?
