This edition of ESSENTIAL magazine deals with “green” and other innovative forms of energy.

In the latest edition of our magazine ESSENTIAL, we deal with one of humanity’s truly special inventions – the capacity to create materials.

Sealing solutions for agriculture face two challenges: extending the longevity of the seal and reducing downtime when the seal is replaced.

Let’s take a look at two seals suited to the beverage industry, and how their design and materials contribute to better-tasting, contaminant-free products.

Earth moving seal kits protect mining, construction and landscaping equipment operating in some of our harshest landscapes.

Bearing rings within hydraulic systems must withstand intense pressures and transverse forces. They are used to protect the system’s metal components from rubbing against each other, and to keep the hydraulic force directed smoothly in the direction required.

The chemical industry needs sealing solutions specific to the chemicals produced, whether they are acidic or alkaline, toxic or harmless.

Pneumatics is the engineering science of how gases under pressure perform work, and pneumatic seals are an important part of keeping those gases under pressure.

Unlike equipment used in regular environments, mining equipment needs custom sealing solutions. Mining locations are harsh and often remote, the demands of 24/7 production punishing.

Mechanical sealing solutions are responsible for nearly a quarter of lost mechanical energy in today’s automatic transmissions due to friction.

Dynamic seals are used wherever there is motion between a mechanical part and a seal, such as between a piston and cylinder.

Let's look at the various applications of dynamic seals.

Freudenberg Sealing Technologies’ custom seals are used widely in the healthcare industry, where hygiene is paramount.

If you’ve seen an excavator or a tilt truck in action, you’ve witnessed the power of hydraulic cylinders and the sealing systems that enable them. Using the pressure of fluid inside a sealed cylinder to drive a piston, no method of linear motion is as strong and efficient.

Depending on the industry, the best sealing solutions perform under a range of environments, locations and applications.

Let's look at how to choose the best sealing systems, considering the different contexts within which each is used.

Whether it’s for home appliances, healthcare equipment or driving excavators, seal materials and designs must be adapted to highly demanding application microenvironments.

If you're buying O-rings online, you sometimes know the exact part number and quantity you need. At other times, you may just know certain attributes of the O-ring you need.

Depending on the application, an O-ring must be resistant to ozone, high and/or low temperatures, corrosive chemicals, oil, fat and cleaning products.

Hygiene is the top priority in the manufacture of food and beverages. Food grade O-rings used in processing equipment have to withstand high temperatures and chemicals produced by raw materials like caramelised sugar and acidic citrus juice.

When it comes to hygienic sealing solutions, the food, beverage and pharmaceutical industries immediately come to mind.

Whether it’s for pumps, wind turbines, excavators, beverage production lines or tunnelling machines, hydraulic seals need to work perfectly every time.

If there’s one industry that needs reliable sealing solutions, it’s food and beverage processing. Mechanical failure or a contamination leak not only causes expensive downtime for repairs, the consequences of a tainted product can be devastating for the brand when publicised.

Sealing systems ensure the integrity of heavy industrial machinery by isolating it from the outside world. Whether its water, dust, air or oil, sealing systems are the border between external and internal conditions.

When we think of hydraulic systems operating in extreme environments, we might think of the Arctic. But there’s a commercial situation closer to home that requires fluid sealing technologies that operate in perpetually cold conditions.

Unscheduled maintenance is one of the biggest headaches in hydraulic system applications. Whether it’s inside the transmission of an excavator, food manufacturing equipment or a diaphragm pump, a failed hydraulic seal means work must stop while the machine’s dismantled.
