I have an elderly horizontal bandsaw with flood coolant. It's pump recently clogged, and in an attempt to free it up, I broke off the tube. Ouch. Looking into the matter, I discovered something cool. The pump is made by Little Giant and I've always been a bit put off by their pricing. However, the cool thing about Little Giant is I can buy parts. An $8 parts order and I'm back in business. How cool is that?
The moral of the story is, if you're considering buying a coolant pump, you might consider paying a little more and getting a brand name Little Giant, or at least checking that parts are available for the pump you do buy.
