What is an impeller? A propeller and impeller are similar, but a propeller pushes against water while an impeller sucks in water. Most modern aquarium pumps use an impeller.

Is your fish tank pump making loud noise? The impeller is the only moving part in most aquarium pumps. Check to make sure the impeller and pump housing is clear of debris and scaling. Check any rubber grommets for wear. Check the impeller shaft for wear and cracks. Check to ensure the impeller magnet is not swollen. Double check to ensure the impeller is properly seated. If none of these steps fix your noisy aquarium pump, you may need to purchase a replacement impeller. It is common for an impeller to need replacement every few years.
