Wear Factors: These components experience wear from the slurry and need to be checked regularly.

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.

   - Consider the type of seal (e.g., mechanical seals, packing) based on the slurry's properties and operating conditions.

Wear Factors: The backplate can wear due to slurry contact and mechanical stresses.

   - Select the impeller design that best handles the slurry's characteristics (e.g., closed impellers for abrasive slurries, open impellers for large particles).
