1.Introduction Mechanical seals are precision devices designed to prevent fluid leakage in rotating equipment such as pumps, mixers, and compressors. Unlike traditional gland packing, which requires frequent adjustment and replacement, mechanical seals provide long-term, maintenance-free operation

1.What is a Mechanical Seal? A mechanical seal is a type of shaft sealing device used in rotating equipment such as pumps, compressors, and agitators to prevent fluid leakage. Compared to traditional packing seals, mechanical seals offer superior sealing performance, longer service life, and lower m
