Help IDing this pump

[Joel_155]

Any ideas what kind of pump this is or what kind of flow rating it has?

This is the only label on the pump

I'm guessing its a Danner 12 Mag pump but I'm not sure. If it is that pump then the flow rating from what I've read online is 1200GPH. I just want to confirm the flow rating so I can plump my tank properly. Thanks for the help!

You are correct, but to get the 1200 gph rating you will need 1-1/2" return piping, any smaller of a diameter and you will not get the 1200 gph. Mags are bulletproof but not very efficient, it will be putting 110 watts of heat to your sump 24/7 so plan for that with the rest of your setup.
