Details
Pump‑type precision castings are produced using the investment casting process, delivering high dimensional accuracy, smooth surface finish, and minimal machining allowances, thereby significantly reducing subsequent machining operations. Material options include a wide range of grades such as stainless steel, alloy steel, and ductile iron, with a dense microstructure free from porosity, sand holes, and shrinkage defects, ensuring excellent pressure‑bearing performance. Our product portfolio encompasses critical pump components—including pump bodies, pump covers, impellers, and shaft brackets—featuring integrally cast flow passages with smooth internal surfaces that minimize fluid‑transport resistance and enhance pump efficiency. Each component undergoes rigorous multi‑stage inspection, including heat treatment, nondestructive testing, and hydrostatic pressure testing, resulting in superior corrosion and wear resistance. These castings are well suited to meet the complete assembly requirements of pumps for chemical processing, water supply and drainage, petrochemical, and metallurgical applications.
