non metallic chain wheel mud scraper Corrosion-Resistant Sludge Scrapers for Sewage Treatment Plants

A non-metallic chain wheel mud scraper system utilizes drive sprockets (chain wheels) manufactured from high-strength, engineered polymers or composites that are paired with a compatible non-metallic chain. This complete non-metallic drive train represents the pinnacle of corrosion and abrasion resistance for chain and flight collectors. The non-metallic chain wheel is precisely machined to mesh perfectly with the polymer chain, ensuring smooth power transmission and eliminating the metal-on-metal contact that is a primary source of wear and a requirement for lubrication in traditional systems. By creating a fully non-metallic interface, the system eradicates galvanic corrosion, operates with a naturally lubricated, low-friction engagement, and significantly reduces operational noise. The absence of mandatory lubrication removes a major maintenance task and prevents hydrocarbon pollution of the wastewater and sludge. This system is ideally suited for harsh environments like municipal wastewater treatment, food processing, and chemical processing plants where reliability and low maintenance are top priorities. The synergy between the non-metallic chain and the non-metallic chain wheel ensures maximum service life and provides the lowest possible lifetime operating cost for rectangular sedimentation tank applications.
