*I hope no one considers this posting a source, I didn't feel it to be so. So here's the ?:
I was looking on some auctions for a Vacuum Pump and kept seeing an amaizingly low price on all GAST brand pumps. I'm not familiar with the brand name, but I mean they looked pretty big ( I know that doesn't mean anything ). As big as the ones that range right around ~$150, but that brand was steady around $17-$49. They looked nice.
Does anyone have any experience with these pumps? I don't think I'll try buying one ( something is just wrong with a pump for $20 ). I mean, a big pump like that would almost be worth $20 broken down and sold for spare parts! I just hate damn aspirators! Thanks!
swim got a DOA model pump of the type you mentioned and it only pulls 150mm/hg. Not good enough for most of the purposes you'll find around here. Try putting a water pump in line on your aspirator. Rhodium has an informative thread on this at his site
