Dry Mechanical Seal

[INQ. NO. 1910E26] Sealink Corp. is a company with cutting-edge technologies. Thanks to the know-how it has built up for over 25 years, it has succeeded in designing, developing and commercializing a non-lubricant dry mechanical seal by dramatically resolving issues arising from the existing oil-lubricated mechanical seals.
Based on its vision to contribute to safety and life respect by reducing leak explosion accidents in the workplace to one-tenth, Sealink is growing into a global company while doing business with Samsung Electronics, LG Chem, Intel (USA), and others.
A day mechanical seal is a sealing unit that prevents leakage of chemical gases, liquids, etc., from cracks between a rotating shaft and stationary housing when mixing chemical substances in an industrial agitator. Such seals are widely applied in petrochemicals, semiconductors, shipbuilding, steel, pharmaceuticals and other industries, and they are especially essential for petrochemical and semiconductor facilities.
The existing mechanical seals need lubrication, meaning they include explosion hazards due to lubricant releases. Meanwhile, Sealink’s dry mechanical seal (called ‘S-Seal’) is safe from leakage-caused explosion accidents and is most suitable for petrochemical and semiconductor machines that are sensitive to lubricant contamination as it is a non-lubricant seal that does not need a device to supply lubricants.
Sealink’s high vacuum and pressure rotary feedthroughs, linear feedthroughs and rotary unions are manufactured and supplied through strict quality-controlled processes in accordance with ISO 9001, ISO 14001 and OHSAS 18001 certifications. And, the reliability tests conducted by the Korea Institute of Machinery & Materials (KIMM) and the secured certificate of reliability have proven that over 95% of the quality of these products is maintained for up to 18,000 hours (or two years) of operation.
