Mechanical Seals

With over 25 years of industry experience, Greene, Tweed solutions for mechanical seals enhance equipment reliability, reduce maintenance, and lower total cost of ownership.

Chemraz® perfluoroelastomer (FFKM) seals and RGD-resistant elastomers (including several FKM solutions) provide broad chemical resistance and tolerate process upsets to prevent leakage and extend MTBF (Mean Time Between Failures). WR® and AR® thermoplastic composites boost efficiency and provide a long service life as backup rings and bushings. And the Arlon® 4020 PEEK material based labyrinth seal overcomes the limitations of traditional metallic versions of mechanical seals. In addition, engineering resources worldwide provide customized technical support for challenging applications.

Greene, Tweed is a member of both the API (American Petroleum Institute) and ESA (European Sealing Association), and has actively participated in the development of equipment and material standards for the petrochemical industry.
