Sorry, i wanted to say if you
power on regular aquarium mag pumps and shoot impeller it will assume the direction you want, because they have no directional artifice.

Just examine one.
Moving back to closed impeller with DC brushless pumps i think that the problems will be:
- short shaft life
- shaft wear
- quickly dead motors
