this is a nice oilless rotary vane pump - normally I test these and
sell them through my web page - but I don't have time right now to do
this and I don't have the space to keep it - see details in the
listing - and please note that this pump is untested and AS IS

By the way, that's a really neat vacuum cleaner you've got on eBay. If I
lived anywhere near you I might be interested, but sadly I don't.

Best wishes,

Chris

Where does the belt go on this One? I have one (which was never
used) with only one fan and the pulley on the other end.

Enjoy,

on this pump, the shaft protrudes through the fan on one side, and you
affix a pulley to the protruding shaft. There is no pulley with the
particular pump I'm offering - you would supply your own. I did put a
link in the auction to the GAST manual page so you can see how the
thing looks new, and what all the pieces are.

I suspect that it will be fine with only one fan, depending on service
- it may well be that in vacuum service there is less heat build up
than in pressure service - I've never measured that - but if you think
about it, in vac service you can only get a max head of 15 psi (but
no flow, so no cooling), but in pressure you can get up to about 30
PSI (but with flow, hence some cooling from the air itself) - which
way generates more total heat - well, that's a fun exercise for the
student - extra credit if you can use both maxwell's equations and the
stephan boltzman law in the solution.

Oh, and I just added a really cool pneumatic controller to the stuff I
have listed - see this link]
