Two Stage vacuum pumps on ebay...

[mwarren]

There are a few very reasonable pumps on ebay that are "rotary vane" pumps. Would these work for Maple?

I'm only going to have 100-200 taps total. Would one of these work?

Hold out for a gast 1550 or 3040. With an electric motor added they work great for maple. I have bought 4 off ebay real cheap.

The first one is 100-200 volt, 50-60 hz. Can you even power that? You would need a transformer to change the volts from either 120 or 240 to that. Find a Gast made for the US market.
