AS Type 212

For: Glass Lined Reactors and Vacuum Devices

AS 212 Mechanical Seal for Glass Lined Reactors and Vacuum Devices.

Structural Features: single end, multiple springs and PTFE bellow working together to provide compensation, balanced, independent rotary direction. The PTFE bellow can resist strong corrosion. The deflection of resistance can reach to 1.5 mm. This seal component has a compact structure and easy to install. When the medium temperature is above 80 ºC, cooling jacket is needed with water cooling.

Industrial Standards: HG/T2057-2003

Scopes of Application: widely used in chemical engineering, pharmacy, pesticide, fermentation, spice production, aginomoto production and water treatment. It is specifically designed for glass lined reactors and vacuum devices.
