Product Code : PS – 250 Welded Ends Metal Bellow Seal is Inherently balanced metal bellow seal. This seals are independent of direction of rotation. The unique feature of this type of seal is that, there is no dynamic 'O' rings and therefore it will never hang up or damage the shaft and sleeve, it also has an ability to handle corrosive as well as abrasive & viscous media.

These seals have self-cleaning & non-clogging construction. With selection of special bellow material it can be used in highly corrosive media.
