How To Deaden The Noise On A Pump?

[VashTheStampede]

Alright, this is no pump like I have ever seen used in water cooling. It would be great for extreme bong cooling, if it were submersible. I'll explain.

My parents have a Water Ace Electric Sponge Multi-Purpose Pump, they used to use it to fill and drain the waterbed, well that waterbed hasn't been in this house for a couple years now, so the pump is all mine.

At 10 feet it does 5 GPM, that's 300 GPH at 10 feet!! It takes standard garden hoses, which, by the help of a local hardware store, have modified with barbs so I can use silicon or rubber hose with hose clamps. I would use this as my standard pump except for one annoying feature... it's TOO damn noisy. Not the normal hum we've come accustomed to with our pumps, but a loud BUZZ from the exceptionally loud motor.

I need suggestions on how to kill this noise. The only one I can come up with is create a wooden box, with Dynamat Extreme to kill the vibration, perhaps putting a 80mm fan pushing air into the box. I don't know. Also on that subject, people have asked how to take a standard AC connector and convert it to 12V DC, I need to know how to do it the other way.

I don't know much about deadening the noise, the dynamat sounds like a good idea, i used to use that stuff when i was wiring up car stereo's at Best Buy. But, i do know that to go from AC to DC you need a low-voltage transformer; at least, that's what my brother, electrician extraordinaire, says about it.
Hope that moves you in a different direction, cuz i don't know much about where to get one or what size or anything.

A transformer just converts AC from one voltage to another (well, it can change the amperage, too, but that's irrelevant, here), you need a power inverter. The best place I know of, to get'em, are truckstops.
If the pump is that powerful, why not put it outside?

yeh, you will want to get a transformer and wire it in at the plug, the best idea is find someone in a shop or someone cleaver and tell them that you want to lover the voltage it is running on, to reduce the sound and ask what to do, a few other ideas are a wood or mdf enclosure which would deaden the sound, i was thinking of the same idea a week ago but didn't do it becuase of the same problems
