SU pumps are polarity sensitive and supposedly while they will run for a
while with RP they will die an early death. Polarity can be changed by
addition of a diode. My recollection is that polarity was indicated by a
broad
rubber band at the head of the pump--one color meant + and the other meant
-. If I am not wrong then I am sure someone on this list knows the emmis
and will share it.

I do not think that polarity plays a role unless a diode is used
