Yes, I meant a piston-powered pump. It's like an engine block, but instead of air-gas, uses water. It is usually gas driven. It's also not usually meant for 100% duty cycle, and requires regular maintenance.

Cieprus, I know you want the best, but you're gonna have to trust us on this, the direct drive or piston-driven is not the best choice. Power is good, but not that much power!!!

What you need is to shop for a pump that:
(pick and choose yourself here)
1-is quiet
2-has a decent flow rate
3-can run continously (i.e. 100% duty cycle) (i.e. is reliable)
4-Requires no (or little) maintenance.
5-Has fittings for your tubing size (or can easily be adapted)
6-Consumes very little power (around 10 to 20Watts is good)
7-Cost little
8-Has been used (therefore proven) for the application that you intend for it (this covers all the other bases I may not have mentionned)

There. What you do from now on is up to you. If you want to use the one you have now, that's just fine. If you want tips on how to isolate it for noise, here's a few:

(but first, keep in mind that if you have to perform maintenance, you'll have to have easy access, and that if your pump requires ventilation, it'll have to be built in. Also, you'll have to route the electric cord)

Basics: to isolate noise...
if you're trying to isolate a high pitched noise (i.e. a beep), then solid objects do that best.
If you're trying to isolate a low frequency noise (i.e. a low rumble), then soft materials do that best.

I can't hear your pump from here, so I'll just give you a few ideas.

a) a wooden box.
b) a steel box
c) a heavy cardboard box
d) a plastic box

You can then add padding, inside or out. You can build a latched cover, if you need access for maintenance. You can cut long slim vents, if it needs ventilation, etc...
