New Low Cavitation Margin Wear-Resistant Preheating Water Pump
The new low net positive suction head (NPSH) preheating pump is specifically designed for the water-coal slurry gasification industry. This innovative low-speed pump features high cavitation resistance, corrosion resistance, and wear resistance, meeting the modern coal gasification industry’s requirements for high efficiency, energy savings, reliable operation, fault-free performance, extended service life, leak-free operation, and easy maintenance.
This new preheating pump features a high cavitation specific speed and exhibits exceptional cavitation resistance. It has become a widely adopted pump type in the coal chemical industry in recent years.
Low Cavitation Margin: Designed with a high cavitation specific speed ratio for superior cavitation resistance. Wear and Corrosion Resistance: Wear-resistant and corrosion-resistant materials used for flow-through components extend service life. Low-Speed Design: Enhances pump scouring resistance and reduces wear.
High Efficiency & Energy Savings: Optimized hydraulic model design ensures high efficiency and low energy consumption.
Structural Optimization: Flow-path components including pump casing, impeller, and pump cover utilize suitable materials and undergo rigorous processing.
Primarily conveys black water with solid content below 10%, temperature ≤120°C, containing trace amounts of NH₃, H₂S, CO₂, and chloride ions. Prone to scaling and corrosive.
