Anyway, the problem is the CTS line of pumps doesn't explicitly say it
is meant for water. I'm wondering it will work anyway. I sure hope
so, because I'd love to order one right now and get this thing working
and very stable. I'd love to get rid of this valve and replace it with
just controlling the PWM. Which leads into my next question, PWM
should work the same with these pumps, right? It won't adversely
effect performance, will it?
Don't have a lot of time to devote to this now

Looks like the CTS and is surplus. They call it an air pump but they
could be wrong - at $15 you could experiment
Air pumps will work with other fluids if the materials are compatible
- water is way more viscous too, the pump would have to turn slowly to
pump water.
Other sites for cheap pumps, when they have them (surplus)

They all have interesting paper catalogs too.
