That's an interesting mechanism of pumping fluids. After
Markus mentioned Bungard and patents I had a quick search
The bungard site is
http://www.bungard.com/seiten/home.htmFor a drawing from the original patent (or one of them) then
go to the link below and then go to the drawing page by
clicking on the "Drawing" button at the top of the screen.
note that this URL may be broken by line wrap around.

Any solvent based glue will be ok in acid. Silicone should
ok, but due to nature of salt solution ("salt creep") I've
found silicone to be less reliable for long periods. Try buy
ready made containers and modify them to suit your needs.
Unfortunaly most molded containers are PP or PE plastic and
cannot be glued at all. The only proper way to make a
container from the beginning is with PVC and a plastic welder.
I'm not sure if the sprayer (its really more of a forceful
splashes) would give the same contact area as lots of fine
bubbles. It'll be something you'll have to just try.
I know with combination of fine bubbles and floating foam
the regeneration is so fast that the solution heats up
significantly.
