Our sand cast centrifugal pump castings are produced using premium materials including ASTM A890/A995 Grade 1A (CD4MCu), EN 10283-GX2CrNiMoN26-6-3, and ASTM A890/A995 Grade 5A (CE3MN) through advanced sand casting processes. The sand casting method allows for complex geometries and large component sizes while maintaining dimensional accuracy and structural integrity. These centrifugal pump castings offer exceptional corrosion resistance, high strength, and reliable performance in demanding industrial environments. The ASTM A890/A995 Grade 1A (CD4MCu) provides excellent resistance to stress corrosion cracking, while EN 10283-GX2CrNiMoN26-6-3 offers superior mechanical properties and corrosion resistance. ASTM A890/A995 Grade 5A (CE3MN) delivers excellent toughness and wear resistance, making our sand cast centrifugal pump castings suitable for a wide range of industrial fluid handling applications.
