Quba’s Double Unbalanced Mechanical Seal DU 810 & DU 815 Series are factory
assembled cartridge units used on mixers, agitators & reactors. The seals are
designed for handling severe services including products emitting toxic vapours
during reaction process. The designs incorporates bearing located very close to
the seal. This standard feature effectively arrests the shaft whip for smooth and
trouble free operation enabling enhanced seal life. The cooling jacket, also a
standard feature, helps to maintain cool environment around the seal.
Large clearance between the rotating shaft/sleeve and mating ring permits
higher deflection of the shaft, invariably associated with top entry agitators.
