  • Impeller vs. Propeller | Pensacola Shipyard

    Both an impeller and a propeller are vital for a boat's operation. However, their purpose and function are very different. A propeller is a fan which propels a fluid by pushing against it: it converts rotational motion into linear motion. An impeller is a rotor that produces a sucking force and is part of a pump.
