Elastomer bellows mechanical seals are a type of mechanical seal that uses secondary seals are molded gaskets made from various types of rubber, resembling corrugations, and are installed in rotating parts to prevent leakage along the shaft.
Elastomer bellows have a larger shaft clamping area than O-rings, providing better protection against leakage of contaminants mixed with liquids. Typically, torque transmission occurs through friction between rubber hoses attached to the shaft, allowing rotation in both directions independently of a spring. Furthermore, its robust structure is resistant to tearing, especially when used in liquids with high levels of sludge contamination.
