What Are PTFE Lantern Rings?

There are a lot of small parts in compressors, and other machinery, that can be hard to understand. PTFE lantern rings are one of those things that you might not know what they are or what their role is.

 

The Rings

 

Polytetraflueroethylene (PTFE) is a synthetic material that is more commonly called Teflon. It is a strong, waxy, nonflammable product. A lantern ring is normally designed with an opening, more often than not a few holes, that allows some sort of lubrication to be applied directly to the bearing surface. The lantern ring makes pump maintenance easier.

 

The Role

 

The reason lantern rings are commonly made from PTFE is because the material is highly chemical resistant, and it can operate even in the harshest of conditions. That means that this ring is able to stay operable much longer than rings made from other materials. Not only is it more durable, but it can be used with more lubricating liquids than metal rings. The role of the PTFE lantern ring is to keep compressors up and running for longer stretches of time with much easier maintenance. These rings are also made to seal in fluids like:

 

  • Oils
  • Acids
  • Grease
  • Slurries
  • Hydrocarbons
  • Pulp
  • Caustics
  • Water
  • Liquors
  • Solvents
  • Paper stock
  • Wastewater

 

When you get a lantern ring that is made of high quality material, you are ensuring that your compressing will work better for longer.

 

Talk to a Professional

 

If you have more questions about PTFE lantern rings, you should make sure to talk to a professional. They will be able to give you more information on the installation and purchasing process. When you talk to a professional, they will be able to help you order your own customized lantern ring. A professional will also be able to answer any of your compressor related questions. No matter what manufacturer makes your pump, you can find a PTFE lantern ring that is right for you.
