Discover why petrochemical and coal chemical industries rely on Dalian Jiachuang’s alloy steel sand casting guide vanes. Featuring Duplex Stainless Steel and Nickel-based alloys for corrosive, high-flow environments.

Cast steel sand casting pump bodies are ideal for fine chemical fluid transfer, where corrosive media, high purity requirements, and long-term continuous operation are critical. Compared with cast iron or non-metallic materials, they offer higher structural strength, better impact resistance, and stronger adaptability to acidic and alkaline media through flexible alloy selection. With stable performance under high pressure and heavy loads, these pump bodies help extend service life, reduce maintenance, and ensure safe, reliable operation across fine chemical, petroleum, metallurgical, and power industry applications.

Recently, Dalian Jiachuang Metal Manufacturing Co., Ltd. (hereinafter referred to as "Jiachuang Metal") has achieved a major technological breakthrough in the field of sand casting. Its independently developed patent technology has successfully solved the manufacturing challenges of OH pump steel casting impellers. According to third-party testing, the comprehensive qualification rate of impellers has increased from the industry average of 85% to 99%, and the production cycle has been shortened by 40%. This achievement not only fills the technical gap in high-end pump castings in Northeast China but also marks the innovative strength of local small and medium-sized enterprises in industrial upgrading.
