Edit: Haha, I should have looked at the picture. That's the same pump I have. 1/2" male NPT (or MPT) fittings, though they might just be straight threads but it doesn't make a difference if you use pipe tape.
I have one of the popular little tan Chinese 12v pumps that were all the rage a couple of years ago on another forum. It was like 15 bucks or less. The general consensus was that it was high temp and food safe. It's actually pretty solid, though people have snapped the threads off while screwing on attachments. I don't use it for brewing anymore (got 2 Chuggers when they were on sale under $100). I'd send you mine but I just used it to cycle Simple Green through my car's heater core and I don't think that smell is ever coming out.
