Mechanical seals are devices used to prevent fluid leakage in rotating equipment, such as pumps and compressors. They consist of two main components: a stationary part and a rotating part. These components create a tight seal between the moving and stationary parts of the machinery, ensuring that liquids or gases do not escape. These seals are essential in various industries, including oil and gas, chemical processing, and water treatment. By minimizing leaks, mechanical seals help improve efficiency, reduce environmental impact, and lower maintenance costs. Proper installation and maintenance of mechanical seals are crucial for optimal performance and longevity.
