A small wheel impeller is a type of impeller used in pumps and mixers to create fluid flow or agitation. It typically consists of a series of small blades or vanes mounted on a central hub, and is designed to move fluid or mix materials in a confined space. Small wheel impellers are commonly used in applications where space is limited or where precise control of fluid flow or mixing is required, such as in laboratory equipment, small-scale industrial processes, or medical devices. **

Additionally, you can try removing the impeller and checking for any signs of damage or obstruction. If the impeller appears to be intact and free of debris, you can also try running the filter to see if the impeller is functioning properly. If the impeller is making unusual noises or not spinning as it should, it may be an indication that it is broken and needs to be replaced. **
