Product Description
Welded Metal Bellow Seals are widely utilized in demanding environments involving high temperatures and aggressive, corrosive media, owing to their dependable performance and suitability for applications requiring high start-up torque. Their reliability in such conditions stems from the bellows design, which transmits torque independently, without relying on conventional mechanisms.
A key feature that sets these mechanical seals apart is the elimination of dynamic O-rings. By excluding these components, the seals prevent frictional interference or damage to the shaft and sleeve during operation—contributing to longer service life and enhanced sealing efficiency.
At the core of the design is a series of welded metal diaphragms, replacing traditional spring mechanisms. This construction provides greater flexibility at the seal face and compensates for wear over time, maintaining a tight seal even under extreme conditions. The absence of springs further enhances the seal’s adaptability and durability in high-stress, high-temperature, and corrosive environments, making it an ideal choice for critical industrial processes.
