High Chromium Cast Iron Slurry Pump Castings (EPC Process)
Hard-core precision casting that defines the new industry standard with extreme wear-resistance for demanding slurry applications.
Superior Material Performance
Our high-chromium white cast iron materials (Cr15Mo3, Cr26, Cr28) feature M₇C₃-type carbides with dispersed distribution, achieving exceptional hardness of HRC58-65. This provides 3-5 times longer service life compared to ordinary castings under high-abrasion conditions.
Advanced EPC Manufacturing Technology
Lost Foam Casting: One-step molding of complex runner systems without parting surfaces or draft angles
Mirror-Smooth Flow Paths: Optimized hydraulic efficiency with improvements exceeding 10%
Precision Wall Thickness: Uniform contours and accurate dimensions through near-net forming
Material Optimization: Significant reduction in machining loss for expensive high-chromium materials
Dense Structural Integrity
Our vacuum negative pressure casting process combined with directional solidification control ensures defect-free castings. Strict melting degassing and component fine-tuning eliminate shrinkage cavities, pores, and inclusions, guaranteeing reliability under high-pressure slurry impact.
