Wear-Resistant Material Technology Upgrade Extends Gravel Pump Service Life
Sep 25,2025
Gravel pumps are widely used in high-wear environments like mining and dredging, where service life directly depends on wear-resistant materials. Recently, high-chromium cast iron (above Cr26), ceramic composites (e.g., silicon carbide), and polyurethane elastomers have significantly improved abrasion resistance. Advanced heat treatment processes enable hardness above HRC65 while maintaining toughness to avoid brittle fracture. The industry trend focuses on gradient materials or bimetallic composite casting, enhancing protection at critical areas (e.g., impeller blade edges) to extend pump life by 30%–50%.
