I would go for the Davies-Craig pump that Cathar mentioned. It has about half the flow, but a very long lifespan of 15000+ hours. And given the insane ammount of flow the CM30P7-1 produces, I may try and throttle it down anyway because of the noise it makes. It's not loud, but I want as silent as possible. I run it on 5V which makes it effectively silent but then flow is insipid. I'll try somewhere around 8-9V (should increase lifespan a bit to boot). Thenagain, I may just replace the pump with a Davies-Craig in the long term.
