I'll be using it for desoldering so I think I want a reasonably strong
vacuum, but the volume is not all that high. It will probably be used in
"burst mode" - with a burst of vacuum for a few seconds being needed
intermittently.
A commercial unit is the "Ped-a-Vac", I think it has a 2-stage
venturi system, and gets a strong vacuum even with some leakage
at the tip. You might look on eBay for one.

I picked up a really neat looking pump for desoldering..all chrome and
nicely made...and when I got it home..the ex asked what I was doing
with a breast milk pumping unit....blink blink....is that what it
is??????
