Oftentimes, aquarium pump manufacturers use the same motor block for different applications. The only thing that changes is the impeller. By swapping impellers, the pumps will move more water and draw more energy. Knowledge of this can be quite helpful to hobbyists, especially those who are constantly flip flopping on how much flow they want in their aquariums or decide down the road they need more flow. Instead of having to replace the whole pump, just swap out impellers.
