An impeller is pretty much a propeller in a tube.

Hmm. I don't know about that. A propeller is intended to "propel" the thing to which it is attached. An impeller as in a pump, moves the fluid, not the thing to which it is attached. One moves the thing to which it is attached, and the other moves the fluid that flows through it.

Impeller is used in the pump for pump the water.
Propeller is used in ship and air craft for to get the motion.

The right answer is that difference of shape...

1. Propeller has blades to transfer the liquids

2. Impeller has vanes to transfer the liquids
