Custom-engineered shaft seals are available fully split to retrofit
blenders, mixers and other rotating bulk process equipment, without the removal
of bearings or drives. The seals offer an effective alternative to packing
glands where they are failing to contain dry powders, pastes, slurries,
corrosives, fluids, solvents, vapors and gases. The manufacturer offers sanitary seal models, which can be
easily disassembled for routine cleaning: ideal for
dry, abrasive powder processes in industries where
frequent product changes and wash-downs are required. Seals can also be fitted
with flush water inlet and drain ports. The seals are built with a
minimum of 6mm of total shaft run-out/misalignment capacity. Many of the
manufacturer’s seals work with an air- or gas-purge system; these consume .25
cfm or less of gas. The patented seal concept is based on the use of a driving
elastomer; there are no internal springs to loosen, corrode or break.
