Technical Specifications and Manufacturing Excellence
Material Grades and International Standards
Our Bronze casting foundry for Pump parts utilizes a range of certified alloys to meet diverse operational and regional standards. We supply components conforming to ASTM B584, BS 1400, DIN 1705, JIS H5120, and IS 305. Key alloys include:
C95800 (Ni-Al Bronze): Offers high strength, excellent corrosion and cavitation resistance, ideal for marine pump impellers.
C83600 (Leaded Red Brass/85-5-5-5): Good general-purpose alloy with excellent machinability for various pump components.
C90500 (Gunmetal): Known for its pressure tightness and good bearing properties.
C92200 (Leaded Navy “G” Bronze): Superior castability for complex shapes.
CNC 2C (BS 1400): A popular British standard bronze for seawater applications.
Manufacturing Processes and Machinery
The production of bronze cast and machined pump components is a two-stage process. First, impeller casting is performed using no-bake sand molding for larger parts and investment casting for intricate, high-tolerance designs. Our foundry is equipped with modern induction melting furnaces for precise alloy control. Post-casting, components move to our machining division equipped with CNC turning centers, CNC milling machines, and vertical machining centers (VMC). This ensures precise adherence to dimensional tolerances typically within ISO 2768-mK for castings and ISO IT8-IT10 for machined surfaces. Final steps include dynamic balancing (to G6.3 grade or better) and non-destructive testing as required.
