The best pumps for these skimmers are the ones that are considered 'high flow'. These are usually low wattage, with large volutes, large inlet/outlet sizes, etc. In short... they do very poorly with back-pressure... they would be great for circulation around the tank, but poor for a sump return. Due to the 2-phase mixing process in the volute, there are some design elements of a good mix-wheel pump that go outside the normal range of design as well. I await what Dave has on the way for a controllable DC skimmer pump. I wonder how much it might be based on [EDIT: let's not rehash that one again... ;) ] Im not sure exactly what you are asking, but I can help. mix-wheel skimmer pumps (needlewheel, meshwheel, etc) are of a certain make.

It seems that there are a lot of pumps out there that are considered "skimmer pumps", but that are sold separately from skimmers (I think Eheim just came out with one). Can you basically switch out skimmer pumps? If so, is doing so effective? I always thought that pumps were matched to skimmers by the manufacturer and putting one on a skimmer that doesn't come stock with that pump would cause problems. How does that work? I ask specifically because I have an external Octopus Pro 250 that seems to have a pump that doesn't work very well (always had problems keeping it sealed and I think the stuff I've used to seal it, which is liquid gasket, somewhat interferes with it's performance). I would love to be able to switch it out with a different pump, but never really believed it to be possible. Anyone know how that whole deal works? Thanks!
