Freudenberg Sealing Technologies can now validate the superior performance capabilities of the intelligent seals it has under development. In addition to their core function, these seals can handle tasks such as sensor applications and monitoring their own state of wear. As a result, they enhance the reliability of machines and systems they help power by providing data about their state of performance and safety. That in turn helps eliminate mechanical failures and unanticipated downtime. A new feasibility study, conducted by Freudenberg Sealing Technologies, has verified the benefits of these sealing functions.

UHMW Seals - Could They Be Right For You?
Ultra-High Molecular Weight Polyethylene, or UHMW, is an inexpensive easy to acquire seal material which, in the right environment, provides an excellent seal.
There are a set of operating criteria which designers should follow to take advantage of the many benefits that other materials like PTFE can’t offer.
In this article, we’ll explore the uses of UHMW, how and where to apply it, and the pitfalls to avoid.
What are the Best Uses for UHMW?
UHMW is used in a variety of seal and bearing applications.
As a bearing, UHMW

Customer Overview
Gallagher Fluid Seals’ customer is a leading global manufacturer of synthetic fibers, filaments, and solid surface materials for commercial and residential use
Customer Problem
- The customer’s slurry pump double cartridge seal failed less than one year after being repaired
- Equipment downtime for the customer’s Bornemann pump cost $15,000/hour. They were unable to produce vital polymers and filaments for solid surface material
- The incumbent supplier’s repair and refurbishment was performed incorrectly with internal components installed incorrectly

Gore® GFO® Fiber vs Graphite/PTFE Packing
When tested alongside generic graphite/PTFE packing, packing made of 100% Gore® GFO® Fiber achieves better results for all key attributes: creep resistance, retention of lubricant, sealability, and stability (shrinkage).
The differences in performances for each generic packings will have an impact on the operational costs.

The ZAVA® Seal-Ring - Quick and Easy Installation
"At last" - that's the reaction of those who have been plagued by the constant need to change rubber seals on VFA and CCA filters at pulp plants all over the world. As an electrician at SCA Pulp in Sundsvall, Frans Sramek is the man that has solved this well-known, and seemingly hopeless problem. The ZAVA seal can be mounted in minute and cuts maintenance costs substantially.
"It’s always a pleasure to be able to offer our customers products on which they make money,” says Lars Bylund, Customer Service Division at Sunds Defibrator.

In the process industry, the Simmerring® Radiamatic HTS II shaft seal ring offers diverse options for its use, such as bottling systems, food equipment, and pharmaceutical and cosmetics units, along with mixers. The key advantage of HTS II shaft seal rings is their high resistance to media since the substances only come into contact with PTFE. This makes it possible to achieve particularly hygienic processes. For approaches based on hygienic design, Freudenberg Sealing Technologies offers dead-space-free variations, such as HTS II 9539 VL with a forward-positioned seal lip.

Gore is working with membrane electrode assemblies in fuel cells to help decarbonize applications from drones to warehouses.
While fuel cells have been around for almost a century, over the past decade their development has rapidly increased because of their potential to produce sustainable energy.
Fuel cells are designed to convert the chemical energy of hydrogen and oxygen into electrical energy. The cell itself consists of an anode and cathode, sandwiched around an electrolyte—a liquid or gel containing ions (also contained in batteries).
W. L. Gore & Associates, a global materials science company with its U.S. headquarters based in Newark, Delaware, produces items derived from fluoropolymers. Gore is also one of the leading suppliers of membrane electrode assemblies (MEAs), the core component that helps to initiate the electrochemical reaction required to separate electrons in fuel cells.
The MEAs produced by Gore is currently

Sealants are necessary in a variety of different facets of life to ensure the preservation of certain products or machinery. This is because sealant are substances that essentially block the passage of fluids or air through the surface, joints, or opening in certain materials, machinery, or piping. There are a wide variety of sealants depending on your needs. If you have heard of hermetic sealing and wondered, what is hermetic sealing, you are in the right place. Below you will find more information on what hermetic sealing is, it’s historical evolution, and what it is used for.
What is Hermetic Sealing?
Hermetic sealing is essentially a watertight and airtight sealant.
