Piston cup seals are critical due to two functions. Firstly, the seal must function as a bearing. If the seal is removed from the hardware, the piston will hit against the cylinder wall. Secondly, since compressors need to run completely dry, the seal provides leakage and wear control.

Supercritical Fluid Chromatography (SFC) with CO₂ Medium
Category
Critical Applications
4 min
Description
A growing global market trend is the increase in pharmaceutical manufacturing and supercritical fluid chromatography (SFC) for purity testing. Many chemicals used in medicinal pharmaceuticals occur in extremely low concentrations and can be difficult to detect with accuracy. Analyses of these compounds are typically performed using gas chromatography (GC) or liquid chromatography (LC).

Compressor Variable Stator Vane Bushings
Category
Critical Applications
2 min
Description
At different speed regimes in the jet engine, the airflow in the compressor is regulated by variable stator vanes (VSV), which are generally located at the initial stages of the high pressure compressor. This area experiences relatively high pressure and high temperature that progressively increases with modern engine performances.

Helicopter Main Rotor Swashplate
Category
Critical Applications
3 min
Description
Flying a helicopter in an unpredictable and changing environment such as the desert or above the sea can lead to the accumulation of several kinds of potential aggressive contaminants, which are not clearly visibly on the bearings of the main shaft of a helicopter rotor. These damaging substances may cause jamming, ultimately leading to crash. The sealing of the swashplate is critical as it protects this aviation equipment from dust, sand, and debris.

100% (CO₂) Certified Polymers For Carbon Capture & Storage Applications
Category
Renewable Energy Solutions
3 min
Description
Because Carbon Capture & Storage (CCS) can achieve significant carbon dioxide (CO2) emission reductions, this process is considered a key and viable option within the portfolio of approaches required to reduce greenhouse gas (CHG) emissions. CCS involves three major steps; capturing CO2at the source, compressing it for transportation, and then injecting into a deep reservoir at a carefully selected and safe site for permanent storage.

Sealed Carbon Dioxide (CO₂) Laser Systems
Category
Leakage Requirement
4 min
Description
Lasers are used in industrial production with high success. Some of the advancements in processing industry would not be possible without lasers. Carbon dioxide (CO2) lasers are among the oldest gas-based lasers. The long lasting legacy of carbon dioxide (CO2) has ensured that their costs remain extremely attractive compared to competing lasers. These lasers continue to command market share on account of their high, continuous power wave operations. They are known for their superior power conversion efficiency, and values in the range of 30% have been recorded. This makes them suitable for sensitive applications such as medicine, as well as demanding applications such as industrial cutting and welding.
