How to clean a clogged stationary seal?

Jul 29, 2025

Hey there, folks! As a supplier of stationary seals, I've seen my fair share of clogged seals over the years. A clogged stationary seal can be a real pain in the neck, causing all sorts of problems like leaks, reduced efficiency, and even equipment failure. But don't worry, I'm here to share some tips on how to clean a clogged stationary seal and get your equipment back up and running smoothly.

Why Do Stationary Seals Get Clogged?

Before we dive into the cleaning process, let's first understand why stationary seals get clogged in the first place. There are several reasons for this:

  • Debris and Particles: Over time, dirt, dust, and other debris can accumulate inside the seal, blocking the flow of fluid and causing it to clog.
  • Chemical Deposits: If the fluid being sealed contains chemicals or minerals, they can build up on the seal surface and form deposits, leading to clogging.
  • Corrosion: Corrosion can occur when the seal is exposed to harsh chemicals or environments, causing the metal to break down and form rust or other deposits.
  • Improper Installation: If the seal is not installed correctly, it can cause misalignment or damage, leading to clogging.

Tools and Materials You'll Need

To clean a clogged stationary seal, you'll need the following tools and materials:

  • Safety Gear: Wear gloves, safety glasses, and a respirator to protect yourself from chemicals and debris.
  • Cleaning Solvent: Choose a cleaning solvent that is compatible with the seal material and the fluid being sealed. Some common solvents include acetone, alcohol, and degreasers.
  • Brushes: Use soft-bristled brushes to clean the seal surface and remove debris. Avoid using wire brushes or other abrasive tools that can damage the seal.
  • Rags: Have plenty of clean rags on hand to wipe the seal dry and remove any excess solvent.
  • Inspection Tools: Use a magnifying glass or microscope to inspect the seal for damage or wear.

Step-by-Step Cleaning Process

Now that you have all the necessary tools and materials, let's get started with the cleaning process:

  1. Shut Down the Equipment: Before you start cleaning the seal, make sure the equipment is shut down and the power is turned off. This will prevent any accidents or injuries.
  2. Remove the Seal: Carefully remove the stationary seal from the equipment. Follow the manufacturer's instructions for removing the seal, as the process may vary depending on the type of equipment and seal.
  3. Inspect the Seal: Once the seal is removed, inspect it for damage or wear. Look for signs of corrosion, cracks, or other defects. If the seal is damaged, it may need to be replaced.
  4. Soak the Seal: Place the seal in a container filled with the cleaning solvent. Make sure the seal is completely submerged in the solvent and let it soak for at least 30 minutes. This will help to loosen any debris or deposits on the seal surface.
  5. Brush the Seal: After the seal has soaked, use a soft-bristled brush to clean the seal surface. Gently scrub the seal in a circular motion to remove any debris or deposits. Be careful not to damage the seal.
  6. Rinse the Seal: Once you have finished brushing the seal, rinse it thoroughly with clean water. Make sure all the cleaning solvent and debris are removed from the seal.
  7. Dry the Seal: Use a clean rag to dry the seal completely. Make sure there is no moisture left on the seal, as this can cause corrosion or other problems.
  8. Inspect the Seal Again: After the seal is dry, inspect it again for damage or wear. Look for any remaining debris or deposits that may have been missed during the cleaning process. If the seal is still clogged, you may need to repeat the cleaning process.
  9. Reinstall the Seal: Once the seal is clean and dry, reinstall it in the equipment. Follow the manufacturer's instructions for reinstalling the seal, as the process may vary depending on the type of equipment and seal.
  10. Test the Equipment: After the seal is reinstalled, test the equipment to make sure it is working properly. Check for any leaks or other problems. If everything is working correctly, you're good to go!

Tips for Preventing Clogged Seals

In addition to cleaning clogged seals, there are several things you can do to prevent them from getting clogged in the first place:

  • Use a Filter: Install a filter in the fluid line to remove any debris or particles before they reach the seal.
  • Maintain Proper Fluid Levels: Make sure the fluid levels in the equipment are maintained at the proper level. Low fluid levels can cause the seal to overheat and wear out faster.
  • Use the Right Fluid: Use the fluid that is recommended by the equipment manufacturer. Using the wrong fluid can cause corrosion or other problems.
  • Inspect the Seal Regularly: Inspect the seal regularly for damage or wear. Replace the seal if it is damaged or worn out.
  • Follow the Manufacturer's Instructions: Follow the manufacturer's instructions for installing, operating, and maintaining the equipment. This will help to ensure that the seal is installed correctly and is operating properly.
