The pump shown is a filter pump that dosent pull down all the way. When you
said there was ajusting knobs I think you have a real vacuum pump used for
vapor deposition and other real jobs. These pumps are expensive new. They
have seperate motors amd pump. Use only pure parifin oil or vacuum oil in it
and it will serve you for many years. If you have what I suspect the new
cost is over $1ooo us new.
