Metal bellow Seal is inherently balanced mechanical seal. These seals are independent of direction of rotation. The unique feature of this type of seal is that there are no dynamic 'O' rings and therefore it will never hang-up or damage the shaft and sleeve. It can handle corrosive as well as abrasive & viscous media. These seals have self-cleaning & no clogging construction. With selection of special bellow material it can be used in highly corrosive media.
