Quba’s Double Balanced Mechanical Seal DB 820 Series & DB 825 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.
