Does anybody have any real world data on this piston version of a vacuum
pump?

http://www.sigmatek.com/1U478-003/1U478-003%20Introduction.htm

I do not have an installation that readily allows a wet pump, and most of
the folks on our field believe that dry pumps are the worst idea that have
been propogated on GA in a long time

Reliability?
Does it provide good vacuum comparable to rotary vane types?
How many hours do you have on it?

Thanks in advance

Doug

Change your dry pump every 500 hours and be happy...
