Materials: Liners are often made from high-chrome alloys, rubber, or other wear-resistant 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.

Another aspect to consider is the volute's performance under varying operational conditions. Centrifugal pumps are often designed to handle specific flow rates and pressures. When the operational conditions stray from those design limits, the volute may not perform optimally, leading to efficiency losses. Engineers often employ computational fluid dynamics (CFD) simulations to analyze and optimize volute designs based on anticipated operational scenarios.

Materials: High-quality bearings are used to withstand the operational stresses.

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