   - Throat Bush: Protects the area around the impeller eye where the slurry first enters.

Materials: Typically made from the same material as the casing or other wear-resistant materials.

3. Wear Plates

Another critical factor in impeller design is the material used for construction. Sewage pump impellers can be made from various materials, including cast iron, stainless steel, or thermoplastics. The choice of material depends on the chemical composition of the waste being pumped. For example, stainless steel impellers offer excellent corrosion resistance, making them suitable for applications involving harsh chemicals.
