Metal Bellow Seal MB 530 Series



Quba’s Metal Bellow Seal MB 530 Series is welded metal bellow seals used in process pumps for high temperature and moderate pressure applications in chemical, petrochemical & refineries. These bellow seals are constructed by welding a series of diaphragms together at the edges. The bellow unit eliminates the need of spring, dynamic secondary seal and provides flexibility to the seal face in addition to compensating for seal face wear. Drive to the seal is given by strong drive lugs, which also protects the bellows from damage.
