Freudenberg Sealing Technologies’ Topographic heat shields are designed for Lithium Battery Systems. Current battery cell and system development (e.g. increased energy density; ultra-fast charging) has a strong influence on the future safety of the battery system:
This market development creates more and more requests for “heat shields” within Lithium batteries, which are placed between the individual cells.
Hydraulic seals are often used for industrial and domestic applications (such as aerospace, electromechanical, climate control, filtration, fluid and gas handling, and process control) to facilitate the separation of liquids. The proper installation of hydraulic seals is vital for efficient operation in hydraulic systems.
There are different types of installation methods depending on the nature of the applications. Whether it's for maintenance procedures or new installations, different procedures are required. However, in both applications, there are common steps to execute to successfully install hydraulic seals.
Here are some tips to install hydraulic seals in a safe environment.
In this new mechanical seal video, GFS Mechanical Seal expert Lino Dimichino, discusses the typical mechanical seal repair and refurbishment process of a cartridge mechanical seal. This important service can help bring new life to your existing mechanical seals without having to purchase a new one.
Many customers of GFS choose to go the route of repair and refurbishment of mechanical seals as opposed to purchasing new ones. It can be more cost effective in many situations, and can make your old seals look just like new.
But what does a repair and refurbishment of a single cartridge mechanical seal look like?
What does a customer do when their application calls for enhanced performance that elastomers alone cannot offer? They turn to GFS partner, Parker Hannifin's uniquely formulated chemical bonding agents which enhance the performance of common elastomeric components by integrating them robustly with metal, thermoplastic, or other component substrates. Using world class process control during the elastomer’s vulcanization process, component substrates become integrally linked to the engineered elastomer, transforming them into a cohesive sealing system.
We are excited to present to you part 5 of our O-ring webinar series. For this portion, Benjamin Mell, GFS Application Engineer and Regional Sales Manager, introduces you to O-ring failure modes. Ben will give a general overview of how and why an O-ring might fail, and how you can determine which kind of failure mode the seal experienced.
Then, Ben will dive into the first two O-ring Failure modes.
The need for easy-to-compress, low-closure-force seals is rapidly increasing in many commercial, electronic and communications applications. If you require efficient, reliable seals for light-weight enclosures with minimal bolts, fasteners or latches in combination with thin sheet metal or plastic flanges, consider low closure force (LCF) seals. LCF seals can drastically reduce the amount of closure force (compression) and the resulting stress generated on the sealed components. These hollow cross-sectional seals offer the seal designer and user a low-closure-force sealing solution for many applications. They can be supplied as either:
To date, the most common method for reducing closure force has been to reduce the Shore hardness of the elastomeric seal material or change to a foam-type of material.
Machining plastics is as much a skill as it is an art form. It takes understanding that whenever you cut a part, it will probably have some motion or energy still within the material.
This is largely because a lot of parts have more rebound than steel in the cutting process. And while plastics are mostly thermally stable, they’re not dimensionally, thermally stable.
Changes in temperature from the time the part is machined, inventoried, and put into service show that typically parts are constantly changing in size. PTFE or Teflon suffer the greatest change in thermal instability where we machine the part, around 74 degrees Fahrenheit.
You might think that if you can make a part and verify that it’s intolerance, then the part is process-capable. But the reality is that a large tolerance range doesn’t make a part process-capable.
Gallagher Fluid Seals is often presented with unique sealing challenges. It's no surprise, considering this is our 65th year in business.
One of our customers, a global composite tank manufacturer, came to GFS with a HUGE request. And we mean "HUGE" literally.
Their fabricated composite tanks needed to withstand media and temperature fluctuations to treat sewage at customer sites across the world.
The caveat: Sewage digestion tanks can range in sizes from 10ft in diameter up to 100+ ft diameters. In this case, our customer's tank sizes were 80 ft diameter.
