MRO Applications for Spring Energized Seals in the Food Processing Industry

Posted On June 01, 2018

Spring-energized seals can solve quite a few problems for MRO (maintenance, repair, and operations) in the food processing industry. Many of the seals used in food processing are mission critical, and a failed seal can cost much more than just repairs and downtime because it can result in contamination.

Factors Influencing PTFE Seal Behavior: The PV Limit - Part 2 in a 3 Part Series

Posted On June 17, 2016

The performance of a dynamic PTFE seal depends greatly on the pressure and shaft velocity involved. In reality, a seal is in contact with only a small area of rotating shaft, which means that the dynamic forces and energy are going to be concentrated there. Much of the energy that comes from the shaft is going to be dissipated in two forms: wear and frictional heat, both of which can reduce the useful life of a seal. An increase in the force that holds the seal lip against the shaft or an increase in the speed of the shaft makes the effects of wear and heat even worse.

Cheat Sheet on Surface Finishes and PTFE Spring-Energized Seals

Posted On April 01, 2016

PTFE Spring-Energized Seal Design

When designing a component that includes a spring-energized PTFE seal, it’s not enough just to specify all the seal parameters; another key part of the design is the surface finish of the mating surface.  In this article, we are going to review what surface finish is, discuss the effects of surface finish on seal life, and then go over recommended surface finishes for spring-energized PTFE seals.

Spring-Energized Seals Jacketing Material



When selecting a jacketing material for a spring-energized seal, engineers look at the

  • operating temperature,
  • pressure (including whether or not it is static or cyclic),
  • dynamic conditions,
  • media involved,
  • amount of seal squeeze,
  • and the geometry involved
In this article, we are going to look at some of the options out there for a polymer jacketing material.

Five Energizers for PTFE Spring-Energized Seals

Posted On July 31, 2015

PTFE Seals

PTFE spring-energized seals are a popular choice for engineers.  The reasons are many, including their long service life, even wear, and their ability to perform in some of the harshest environments.  They work well in extreme temperatures; can even perform well in situations where operating conditions can vary significantly.  They usually offer a low compression set, have a long shelf life, and work very well in non-lubricated applications.  The use of PTFE results in extremely low friction and excellent chemical compatibility and users can choose from a variety of spring energizers.   

As one of the key components of a spring-energized PTFE seals, each of these energizers offers a different set of characteristics that allow engineers to find just the type of seal to suit their application’s needs.  In this article, we ae going to look at five different categories of energizers, and in what conditions they provide the best service:  coil springs, V springs, helical flat springs, cantilevered finger springs, and elastomeric O-rings.
