The disc material is duplex stainless steel, such as 2205, 1.4529 and so on, which have extremely strong resistance to chlorine ion corrosion (resistance to chloride ion 40000ppm), high surface hardness and strong comprehensive mechanical properties, especially for slurry application. Austenitic stainless steel can also be used according to the working condition. The disc and resilient rubber sealing combination realizes bubble tight sealing. The connection is wafer type.
