   - Concentration: Measure the percentage of solids by weight or volume in the slurry.

Wear Factors: Impellers are subject to high levels of wear due to the abrasive nature of slurries.Materials: Common materials for impellers include high-chrome alloys, natural rubber, and polyurethane.

Materials: Materials used for shaft sleeves include hardened stainless steel and ceramic-coated materials.

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.

   - If needed, consult with industry experts or engineers to validate your selection and ensure optimal performance.

   - Mechanical Seals: Provide a tight seal and reduce leakage.
