METAL BELLOW SEAL

ACCURATE designs various types of "metal bellow" seals which are constructed by welding series of diaphragm together to form a bellow unit. The bellow unit eliminates the need of springs & provides flexibility to the seal in addition to compensating for the seal face wear which allows the seal to never hang-up or damage the shaft & sleeve. These seals are used for high temperature moderate pressure application pumps which uses corrosive, abrasive & viscous media like highly corrosive chemical, petrochemical, & refinery process units. These seals are independent of direction of rotation & suitable for process services requiring corrosion resistance. The seals have self-cleaning & non-clogging construction.
