The FC has a check valve in it and just the F does not. I think the F means it is a flanged model.
The single speed pumps have UP before the number and 3 speed pumps have UPS.

Is that it? They could leave that check valve out but include it in the box. Ive literally removed the check valve in 99.9% of my installs.

I thought the FC is for open systems and F for closed. I guess that's not the case and its fine to use on my OWB.
Thanks guys.

I checked with Grundfos and was told it is an OEM pump, so that's why its black. Thanks for your help.
I have to put the pump on and then start cutting...not one peice of wood ready for the winter!
