A submersible pump, as its name implies, is submerged below the surface of the liquid, where it uses a propellerlike device called an impeller to move the fuel upward. Slanted blades on the rotating impeller push the water the way the blades on an electric fan push air. A suction pump moves the gas using the principle of unequal pressure.
