>I wonder if someone could shed a little light on the different types of vacuum pumps? Vane-type pumps were referenced in the earlier thread. Today I looked at a used Sargeant and Welch pump that had an oil reservoir between the motor and the pump. I've heard mention of oil-bath pumps, but don't know what that means exactly.
Any info would be appreciated. I intend to buy a vacuum pump when I find a good deal, but I'd like to know a little more about them. References to online articles would also be helpful.
