mechanical seals with elastomeric bellow

Mechanical seals with elastomeric bellow

The use of an elastomeric bellow as a secondary seal to the shaft has several advantages for the design of a mechanical seal. Thereby the bellow acts as a complex central component part, which also performs other tasks besides its sealing function. One of these tasks is the transmission of the friction torque from the sliding surface to the shaft (type IFK and IFA) as well as the retaining and sealing of the seal ring inserts. High quantities in production allow low manufacturing cost at a high technical quality.
