Pump Impeller Material Selection

Common materials for pump impellers include cast iron, stainless steel, and composite materials. Cast iron impellers offer good corrosion resistance and wear resistance, making them suitable for general water and wastewater transport. Stainless steel impellers are suitable for transporting corrosive liquids and are commonly used in the chemical and pharmaceutical industries. Composite material impellers, on the other hand, offer lighter weight and better corrosion resistance, making them suitable for use in special operating conditions.
