Bob, with pumps so cheap, why do you want a air pressure based system?


Can't use a water based coolant. Can not. Will destroy mill. Water
based
is not an option.


'yes and? Pumps will pump other stuff than water.......G


I am not seeing one rated for oil or other petro chemicals for less than a
couple hundred bucks for just the pump. Tank, filters, etc are extra. Not
sure what cheap pumps people are talking about. Any ole water pump will
work for a water soluble coolant. Probably could use a cheap swamp cooler
pump for those coolants. Used to be about $9 whole dollars retail for the
economy ones when I was in the hardware business. A good one was less than
20.
