Are rotary pumps that large? From what I can tell, they’re relatively small as long as we’re talking the ones sized for single group machines.

Yes, they are pretty big. Just the pump alone is larger than the pump + motor for a vibe pump, and the motors for rotary pumps are like 4-5x the size of the pump. So you're really approaching 10x the size, it's kinda wild.
