5 Ways to Kill a Mechanical Seal During InstallationMechanical seals are vital components in industrial machinery, playing a crucial role in preventing the leakage of fluids or gases between rotating and stationary parts. They are extensively used in pumps, compressors, and a wide range of other mac

A Mechanical Seal is a fundamental component in virtually every rotating pump application. Its job is to prevent fluid leakage between the stationary pump housing and the rotating shaft—a role that helps ensure system efficiency, safety, and environmental compliance. Despite being designed for reliability, Mechanical Seal failures are among the most common causes of pump downtime and maintenance costs in industrial operations. In fact, studies estimate that up to 90% of mechanical seals fail due to reasons other than simple wear and tear, including installation errors, improper handling, and system design issues.

A Mechanical Seal is one of the most important yet often misunderstood components in modern industrial equipment. Across countless sectors—from chemical processing to water treatment, power generation to petrochemical industries—the Mechanical Seal plays a vital role in preventing fluid leakage, reducing environmental impact, and improving operational efficiency. With the global Mechanical Seal market poised for significant growth and technological evolution, understanding what a Mechanical Seal is, how it works, and why it matters is essential for engineers, purchasers, and decision‑makers alike.

FBU Successfully Delivers Type APOG Seal for Flowserve® ERPN

​We have successfully completed this renovation by removing the original packing and dynamic seal and replacing them with a brand new cartridge double mechanical seal designed by FBU. Currently, it has been successfully used on the customer's site for three years, helping them save costs, water, and protect the environment,Everyone at FBU is very happy and thinks it's very meaningful.
