DESCRIPTION
Mechanical Seals are precision engineered sealing devices designed to prevent leakage between rotating shafts and stationary equipment housings in pumps, compressors, mixers, and other rotating machinery.
Mechanical seals operate by creating a controlled sealing interface between a rotating seal face and a stationary seal face. Compared with conventional gland packing, mechanical seals provide superior sealing efficiency, reduced leakage, lower maintenance requirements, and longer equipment service life.
These seals are widely used in industries such as oil & gas, chemical processing, water treatment, pharmaceuticals, food processing, marine engineering, and power generation.
