204 Mechanical Seal

 

Type 204 mechanical seal for the kettle is a single end face, multi - spring balance structure. The transmission screw is used for transmission. Due to the use of multiple springs, the spring pressure distribution is uniform and adjustable. The balance structure makes it adapt to a higher range, so it is one of the two most widely used cauldron seals. It is suitable for sealing stirring shaft of reaction kettle in chemical industry. The friction auxiliary material and auxiliary sealing material should be selected according to the actual working conditions.
