I know pinwheel or needle wheel are popular for skimmer applications because they do such a good job at chopping up the bubbles into tiny bubbles.
I would assume a pump that is designed to just bring water from one are to another wouldn't necessarily need or have a pinwheel impeller though since without the air input there really wouldn't be any need to chop up bubbles. No?
