Formed metal bellows
Knife edge seal
By using a formed metal bellows and providing a sharp knife edge structure on one end of the sliding material, this seal has been developed to exhibit stable sealing performance for high viscosity fluids, polymerized fluids and coagulative fluids. The “WAK” type has a rotary structure.
High-viscosity fluid, polymerized fluid, fluid containing slurry
