Quba’s Metal Bellow Seal MB 510 Series & MB 515 Series are welded metal bellow seals used in chemical, petrochemical and refinery process pumps for moderate temperature and pressure application and for process services requiring corrosion resistance. These bellow seals are constructed by welding a series of diaphragms together at the edges to form a bellow unit. 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.

Applications:

Chemicals, Petrochemicals, Refineries & Corrosive Chemicals.
