Elastomer Bellow Mechanical Seal

Design with elastomer bellows has got very good secondary sealing on a shaft. It is highly recommended for sealing media with possibility of crystallization or containing solids in waste water or sewage application. Reparation is very fast and cheap. These type of seals do not depend on direction of shaft rotation.


Operating limits:
p = 12 bar
t = -20...120 ^oC
v = 10 m/s

Elastomer bellow mechanical seal, relatively cheap and very popular type of mechanical seals.
