What is a Mechanical seal?

A mechanical seal is a sealing device used to prevent leakage of liquids or gases between rotating shafts and stationary parts, such as in pumps, compressors, and mixers. Mechanical seals are critical in maintaining the efficiency and safety of rotating machinery by keeping fluids contained, preventing contamination, and reducing wear on machine components.

Structure and Principle: A mechanical seal typically consists of two primary components:
・Stationary part (stator): Fixed to the casing of the equipment.
・Rotating part (rotor): Attached to the rotating shaft, creating a seal with the stationary part.
The seal prevents leakage by maintaining a very small gap between the moving and stationary parts, and is often lubricated or cooled to reduce frictional heat. This helps to extend the seal's lifespan and ensures continuous operation in demanding environments.

Features:
・High sealing performance: Prevents leakage of liquids or gases in rotating equipment.
・Durability: Designed to endure long periods of operation with minimal maintenance.
・High pressure and temperature resistance: Can be designed to handle extreme conditions, including high pressures and temperatures.
・Wide application: Used in industries like chemical plants, oil and gas, food processing, and power generation.

Application of Mechanical seal

１．Pumps: Mechanical seals are used in pumps to prevent fluid leakage and enhance operational efficiency.
２．Compressors: Used in compressors to seal gas and prevent leakage, ensuring safe and efficient operation.
３．Chemical plants: In chemical processing, mechanical seals prevent the leakage of hazardous substances, protecting the environment and ensuring safety.
４．Food industry: In food processing, mechanical seals help maintain hygiene and prevent contamination of food products.
