40x turnover rate enough for BB tank?

i'm going to have my 50g be barebottom and i'm wondering if a mag 7 return pump and a Gen-X PCX-100 as a closed loop be enough flow.

that would equal about 2000gph in the tank.

Probably not. Depending upon the aquascaping/layout, you will likely need more (at least pointed toward the bottom, not necessarily throughout the tank). What you have going throughout the tank itself will depend on the corals.
