I'm looking into a DIY TIG cooler, and want to see if I can connect a Procon pump to a motor I have. Is there a specific name for the "round shaft with a flat surface" on this pump? I want to see if McMaster or a similar outlet has a fitting for it.

can get a procon pump and motor cheap on ebay here is one for 45 buck and like 30 shipping http://www.ebay.com/itm/PROCON-PUMP-...item337b152bf2 plus the seller has a 100 percent selling score like the way the pump is mounted on motor

What you need is a shaft coupler. There are two ways to go, one is to use a solid coupler, and then the pump basically hangs on the motor. Then you use a small reaction arm to keep the pump from spinning. This is done on motors with good quality end bearings. The other way is to mount the motor and pump solidly, and use a flexible coupler between them. These are made by Lovejoy and others and deal with small amounts of misalignment. What you can't do is have a solid coupler and solid mountings. It will damage both pump and motor.

I guess I forgot about belt drives, Rod.

Thanks for _that_ heads-up, I'd already started walking down that road. Time to reconsider! The motor I have is set up for belt drive; maybe I'll give that a thought. The thinking through and designing and problem-solving is fun, but hard to pass up a pre-built setup like the one Rod posted.

Here is another procon type pump, these are used for coffee machines, You can use a love joy type coupling , a chain coupling , or a flat belt flex coupling to hook to a motor.
These are new http://cgi.ebay.com/ws/eBayISAPI.dll...e=STRK:MESE:IT

Here is a version of the close coupled type used on many coolers. They are all over ebay, if you look around, I'm sure you'll find something that you want at a price you are happy with.

Its much better to have the motor hook to the pump like the carbonizer setup. Here is the build I did with a carbonizer setup.

If you have a lathe you can attach the fan on the same motor for a smaller unit. I copied that from another guy's post.
For a hobby guy building it is where it at.

I disagree. Ready built computers usually have a one part selling point like the processor, while the rest of it's parts are low end (motherboard, memory, power supply, hard drive, case). You can have all have all high quality (Faster) parts for about the same money, and a clean operating system without all the garbage/spyware that comes with a pre-installed OS. You also get to put it all in a quiet case that you like.

Yeah, another reason not to go with belts is the pump is likely not intended to have a lot of sideways pressure on the shaft. Tom, what lathe operation did you perform to attach the fan to the opposite side of the motor?
Also, does a system such as the one pictured require that it be completely full of fluid at all times? If the fluid level went low for any reason it seems (to my admittedly untrained eye) that the pump would have to push a combination of fluid and air. In the photo, fluid leaves the tank and has some straight up vertical travel before reaching the inlet side of the pump (assuming it is on the right as you face the label on the pump). Seems like any air in the system would collect there, and the pump would have to overcome that. Certainly not intending to be critical of your system, Tom, just trying to make sure I understand the tolerance for air, or if I'm just plain overthinking it or missing the point.

Here is the guy's video that I copied the motor mod
http://www.youtube.com/watch?v=e-6YxrGU6Ok
Take the motor apart and use a lathe to drill a 1/4" hole in the motor shaft on the other end from the pump. tac weld a 1/4" rod in the shaft for the fan to go on.
I bought a aluminum fan from Graingers.
The procon pump is a positive displacement type and it does not have a problem pulling water up from the tank. Any air is cleared from the circuit after a very short time. If you can get a carbonizer buy it you will get the motor, pump, some fittings, and tank from it. I had to redo the tank as shown in the picture and its SS so thats a plus.

Thanks for the link- he's got a lot of good ideas going there. Not only the fan on the motor, but the heater core (still available for $26) and the way his whole setup sits on the reservoir.
Thank also for the procon info. I'm watching a couple complete pump / motor / tank setups on ebay.
