What's wrong with this picture?

The only problem with trying to cut through the epoxy is that the intake cap thingy with the barb screwed in it goes into the pump housing by about a 1/2 inch. I epoxied around that as well, most of the epoxy is inside the pump where I can't possibly cut through it. On the positive side, the pump is now completely silent when I plug it in.

That's always good At least you got your goal of quieting it down.

now, only if it pushed water

LOL sell it on ebay as the worlds quitest and most efficient water pump

Actually I'd try heat...a heat gun or even some boiling water. Heck, it's a submersible pump, you could even throw it in a veggie steamer.
Epoxy sets by a thermal reaction, and it turns back to goo when you apply heat.

Now I don't know how much heat it would take, and at what temp the pump starts melting. It's not like it's gonna cost anything at this point to try.

Well, I froze the pump for about an hour, and managed to get the barbs out. I can't get the intake cap thingy off though. I also managed to break off one of the finger tabs on the intake side. On a side note, I thought epoxy set because of the evaporation of the solvent.
