Hello again bees!
After carefully considering my options and lots of research and being a total novice oz bee, i've decided to drop the idea of buying a vacuum pump or messing around with fridge compressors.
Instead, i have aquired a second-hand Davey water pump, which has a 0.6hp motor and produces about 50PSI pressure at zero suction depth.
I will be building a recirculating aspirator stating simmilar to the one discussed on the web site using this pump.
I am also aquiring a brass water/air aspirator, which i am going to hook up to this pump. The aspirator is fitted with a non-return valve.
For measuring the vacuum created, i am planning to use an automotive boost/vac gauge. These gauges are relatively cheap over here, and the one i am looking at has a range of 30" Hg to 20 PSI, should be able to tell me approximately what vacuum my aspirator is generating.
Could someone please tell me if i am on the right track so far?
Thank you,
Sponsan.
