   - Locate your required flow rate and head on the chart to find potential pump models.

Function: The expeller and expeller rings work together to reduce the pressure and minimize leakage from the pump.

Materials: High-chrome iron, ductile iron, and stainless steel are commonly used materials.

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.
