I'm surprised no one has mentioned wet vacuum pumps. I'm considering a
wet pump when the current dry pump gives up the ghost, as it sounds like
wet pumps are nearly bullet-proof. That said, I have been lucky in that I
still have not had a vacuum pump go out on me. I have had several gyros
fail though.
