Double Unbalanced Mechanical Seal DUS 910 Series & DUS 915 Series are factory assembled cartridge units used on mixers, agitators & reactors. This 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.
