There are several types of impellers used in sewage pumps, each with distinct features catering to various types of sewage applications. The most common types include open, semi-open, and enclosed impellers. Open impellers have no front shroud, allowing for larger solids to pass through without clogging. This makes them ideal for handling raw sewage containing debris. Semi-open and enclosed impellers, on the other hand, are more suitable for cleaner liquids, offering better efficiency and pressure generation.
