recently had a compressor pump go out. Have tried to find parts and get NLA-(No Longer Available).
So I have decided to take my 60 gallon tank and build one. Any suggestions on pump and motors?
I do a lot of impact, air chisel work.
We would need a little more info like what is the air tank rated for in WP (working pressure). How many HP is the motor you have? what is it's FLA (full load amps) I built a single stage 50 gallon compressor with a three cylinder pump (slower, cooler and quiet) and a 3 HP 230 volt motor. It works for me for most needs and a little body work now and then. Had to make the belt guard which was a pain
My compressor shown above is a 3 HP 230 volt setup and I'm quite happy with it for use with body tools and spray guns. I could not recommend it for a sand blasting rig but it sounds like it would work for you. Just get the pump, most of the other parts you already have and can reuse them.
3 cyl $299 single stage
oops I didn't see the voltage in your post 14 amps @ 120 volt is 1.5 HP
14 amps @ 230 volts is 3 HP
What you need will depend on how many CFM you must have. The compressor above produces 10 CFM @ 100 PSI all day. A 1.5 motor can only drive a very small 2 cylinder pump at 6 CFM max. There also is the real estate available on the tank plate to mount motor and pump. On my tank the previous owner welded ears and extended the plate. This is a dangerous thing to do, I don't recommend doing that unless you are a certified welder. You could always bolt a lager plate on as an option.
