Sealing Expertise for Solar Energy
Freudenberg Sealing Technologies announced they developed special, innovative seals that are in high demand for solar energy facilities.
Optimal Seals for the Optimal Price
The groove profile in the customer‘s plastic application proved to be a challenge for the seal’s design. Available tolerances and specific installation spaces had to be taken into account. “We were looking for the right material as we proceeded with calculations and simulations,” recalled Ralf Schmid, Senior Vice President, Special Sealing Division at Freudenberg Sealing Technologies. In the end, the company’s expertise in engineering and materials won the day – all the more because the sealing rings were designed for an operating life of 30 years. “We developed the optimal product at the optimal cost, eliminating the customer’s concerns relating to a critical

Seals are small components that have a big function. At their most essential purpose, they keep fluid in and debris out. Failure to do this can lead to costly machine destruction, and even endanger the lives of people working around these machines. Preventing seal failure is very important on many different levels.
What Seals Are Up Against
Many factors can cause a seal failure. Being aware of these factors will help you in preventing an avoidable failure. Seals are under constant pressure because of the liquid or gas being contained. Typically, the seals in pipes or machinery have some type of matter within transferred at high velocities. This is a huge part of what they were designed to do, but too much or too little pressure could wear down the seals.
In addition, extreme temperatures can cause the seal to become brittle. A mixture of extreme temperatures and pressure is a recipe for cracking and leaking. Also, debris can contaminate the integrity of the seal. Even

Four-foot diameter lantern rings solve corrosion issues at Hoover Dam hydro plant
When engineers at Hoover Dam determined that the original cast iron lantern rings built into some of its turbines needed to be replaced, they were looking for a solution to help them overcome the corrosion issues they experienced with the cast iron.
The maintenance team also faced another challenge. The Colorado River serves as a water source for the Hoover Dam hydropower station, and the water in this area is commonly referred to as “hard water” due to its high mineral content, specifically high levels of calcium and magnesium ions. Aluminium lantern rings that were first tried as a replacement, were corroded by chemical reactions with the minerals in the water.

KLINGER® QUANTUM
Unique gasket material with the highest flexibility at high temperatures
KLINGER® Quantum is the first fiber reinforced gasket material in the world that is exclusively HNBR-bound. Together with a unique production process developed specifically for the purpose, this material can be used at higher temperatures and with a much wider range of media than any other fiber reinforced gasket material that is currently available.
This material is suitable for use in oils, water, steam, gases, salt solutions, fuels, alcohols, weak organic and inorganic acids, hydrocarbons, lubricants and refrigerants. KLINGER Quantum is manufactured with a high-quality fiber and filler compound reinforced with a high temperature resistant HNBR matrix.

In appliances used for water purification and carbonated water, the valve of a carbon dioxide cartridge and the pressure-reducing valve on the device itself must be joined with a secure seal. Now, Freudenberg Sealing Technologies has developed a patented, high-performance polyurethane seal for a customer that has a specific geometry that not only accommodates different valve dimensions on the various gas cartridges, but also offers high impermeability under long-lasting pressure.
Drinking water is heavily contaminated in many countries around the world: Pollutants such as microplastics, bacteria,

The world has entered a pivotal moment in water treatment, and the challenges continue to worsen as municipalities grapple with the risk of encountering premature failure in elastomeric gaskets. Such a risk brings up several problems, including reduced efficiency, sudden equipment failure, costly maintenance and downtime, and perhaps worst of all — contamination.
Prior to 2013, gasketing products were not subject to the NSF61 (Drinking Water System Components – Health Effects) standard, leaving a critical gap in the safety and compliance of materials used in contact with potable water. However, as the demand for reusing treated wastewater grows, the influx of chlorine and chloramine levels — ensuring potability — has exposed the vulnerability of elastomeric gaskets. This has emerged as a serious issue.
In the ever-changing world of water treatment, it is important to address this challenge and explore innovative solutions to safeguard the reliability and longevity of gasketing

Press-in-Place Seals (PIP) from Parker
O-rings are a universal seal throughout the world. However, some axial applications may benefit from a different sealing solution called Press-in-Place seals, or PIP seals.
First, let’s define axial seal. “Axial” implies the seal is being compressed from top to bottom. In other words, the seal is pressed between two flat surfaces. One flat surface has a groove cut into it to retain the O-ring and limit compression. This may also be called a face seal.

Comparing Conventional Elastomers to DuPont™ Kalrez® FFKM
Today, we continue our series on the world’s most popular perfluoroelastomer, Kalrez.
The agenda for part two of our video series on FFKM will compare conventional elastomers vs. Kalrez®. We will take a deep dive into what makes Kalrez so special for a wide variety of industries and applications worldwide.
Since Kalrez® parts are predominately used in sealing systems, it is useful to review the basic properties of the most popular seal materials compared to the world's most well known FFKM, Kalrez®.
