Centrifugal pumps are typically constructed from a variety of materials, depending on the application and operating conditions. Cast iron, stainless steel, and bronze are common materials used for the pump casing, impeller, and other components. These materials offer a balance of strength, corrosion resistance, and cost-effectiveness. In more specialized applications, such as high-temperature or high-pressure services, exotic materials like titanium or specialized alloys may be used. The selection of materials is critical to ensuring the pump’s reliability, durability, and performance over its lifespan.
