No Leakage in 10 Years with Kalrez Perfluoroelastomer Seals
Dramatic increases in instrument performance and reliability have been achieved where original PTFE gasket seals have been replaced with Kalrez® custom gaskets from the Qnity™ Performance Polymers range of products.
A Finnish manufacturer of process refractometers was utilizing process media at temperatures ranging from -20° to +220°C and pressures from 0.7 bar to 25 bar. These aggressive operating conditions resulted with the PTFE seals needing to be regularly replaced on a 6-12 months operating cycle.
However, after the seals were replaced by Kalrez® custom gaskets, there was no experience of fluid leakage over a 10 year period, even though the sealing products were subject to permanent in-line fluids immersion during this period.

When to Choose Metal Cased Lip Seals
In rotary sealing applications, durability and reliability are often the difference between smooth operation and costly downtime. While elastomeric seals have their place in many systems, there are situations where a more robust solution is needed. That is where metal cased lip seals stand out.
Metal cased lip seals are designed for demanding environments where equipment is exposed to

Protect Motor Bearings from Premature Failure
The Orion Engineered Seals patented Bearing Protection Device (BPD) represents state of the art bearing protection technology and is the premier non-contacting bearing protection device offered. The BPD was designed with an understanding of the nature of the bearing housing environment under all operating conditions and utilizes the laws of physics to create what has proven to be the best performing and most cost effective way to protect the bearings of your rotating equipment.
BPD-GB - Motor Bearing Protection Device
Problem: The increased use of VFD’s offers substantial efficiency improvements. However, a key drawback is stray VFD generated currents that result in premature motor bearing failures.

Understanding the Challenges of Rotary Sealing
At first glance, sealing a rotating shaft may seem straightforward. In reality, rotary sealing is one of the most technically demanding areas in sealing engineering. From high-speed electric motors to mining equipment operating in abrasive environments, rotary seals are exposed to a unique combination of friction, heat, pressure, and wear that many other sealing applications never encounter.

The Future of Seals: Identifying and Communicating Levels of Wear
Seals do their jobs tirelessly, usually behind the scenes. Until now, machines mostly had to be dismantled to check the condition of these parts. That’s expected to change: At Freudenberg Sealing Technologies, a cross-disciplinary team is testing seals that identify and communicate their level of wear. They are based on a novel material that functions as a sensor.
