non metallic chain scraper system Non-Metallic Sludge Scrapers for Corrosive Media | 18-Yr Expertise

A non-metallic chain scraper system utilizes engineered polymer or composite materials for the entire load-bearing chain and its associated drive sprockets, representing a paradigm shift from traditional steel systems. This technology addresses the fundamental weaknesses of steel in the corrosive and abrasive environment of sedimentation tanks. The non-metallic chain is completely immune to electrochemical and chemical corrosion, whether from saltwater, hydrogen sulfide, acids, or alkalis present in the wastewater. It also operates with a natural lubricity provided by the material itself, eliminating the need for messy and environmentally problematic oil lubrication systems. This creates a cleaner operation and prevents lubricant contamination of the sludge. Furthermore, these chains are exceptionally resistant to abrasive wear from grit and sand, often outperforming steel in terms of service life. In a demanding application, such as an industrial pretreatment plant, the switch from a steel to a non-metallic chain system can transform maintenance schedules, shifting from frequent, costly chain replacements to a virtually maintenance-free operation for years. The reduced weight of the non-metallic chain also contributes to lower energy consumption for the drive system. For any facility plagued by the endless cycle of corrosion, wear, and high maintenance associated with metallic chains, the non-metallic chain scraper system offers a robust, long-term solution that drastically reduces the total cost of ownership and improves operational reliability.
