Traditionally, impellers have been made from metal or plastic coated metals. These suffer badly from wear, thus contaminating the chemical, which in clean environments is unacceptable. Also, corrosion, particularly for metallic impellers, also contaminates the chemical. This wear and corrosion results in often short lifetimes for these impellers.
Advantages of Using Sialon Impellers
International Syalons manufacture ceramics impellers which in many instances solve these problems. Syalon 101 is a ceramic which possesses excellent corrosion resistance and wear resistance. For example, Syalon 101 is resistant to corrosion by many acids, such as boiling hydrochloric and sulphuric acid, and alkaline materials, such as sodium hydroxide. This chemical stability, combined with high strength, hardness and toughness make Syalon 101 an ideal material for many demanding chemical applications.
