I have two DCP-18000's. One running a skimmer and one as a return. I have the same setup as you, 220 display and a 60 frag, except mine is all in the basement. You will not get 2000+ to the display at 14' plus plumbing. Just not gonna happen. Your going to need to stick with a head rated AC pump for that. The tech just isn't there yet with DC pumps.
Both pumps are internal running 100%, I am running a chiller and UV from a manifold on the return but the best I've seen is about 1700gph on the return line with the manifold shut off. I have about 6' vertical lift and about another 6 to 8' of head with the plumbing. The skimmer runs 1-1/2 PVC and steps down to 3/4" at the injector. Maybe 1.5' of vertical lift and 5' head in plumbing. But you can really see the restriction at the injector in the flow rate on the skimmer.
