Understanding Mechanical Seals: Key Facts for Installers

Mechanical seal installation is a critical process that requires precision and experience. Improper installation can lead to premature seal failure and equipment damage, which can be costly for industrial sites. Let's take a look at an example of an incorrectly installed mechanical seal on a centrifugal pump.

Identifying the Issue

The installer was unable to stop the pump from leaking, despite using a standard Type 21 mechanical seal that was correctly specified for the application. Upon investigation, it was discovered that the elastomer boot on the stationary seat had rolled out of position during installation, likely causing the leakage.

The Consequence of Neglect

Instead of addressing this minor installation error, the installer decided to add a second mechanical seal facing. This hasty decision only compounded the issue and could potentially lead to further problems down the line.

The Solution: Precision and Expertise

Proper mechanical seal installation requires attention to detail and expertise. Each component must be carefully aligned and secured to ensure optimal performance and prevent leaks. By following the manufacturer's guidelines and utilizing the correct tools, installers can avoid costly mistakes and ensure the longevity of the equipment.

Remember, when it comes to mechanical seal installation, precision is key. Taking the time to do the job right the first time can save you from headaches and expenses in the future. Trust the process, follow the guidelines, and seek help from experienced professionals if needed.
