Woodex Bearing Company, Meco Seals Division

Meco introduces its newest shaft seal design: the outside face seal (OFS). These single-face seals were originally designed for high-temperature and high-speed applications where double-face seals can overheat and fail. Earning Meco its most recent patent, the OFS is particularly suited for the containment of vapors in vertical-shaft vessels, where long, cantilevered shafts can exhibit high runout (6 mm+) and misalignment. The OFS seal will also permit significant axial shaft motion, making it ideal for applications where there is end float or thermal expansion of the shaft.

OFS seals excel in vacuum environments, often cutting process times in half by containing a high degree of vacuum. The OFS is available un-split or fully-split, and in a variety of materials combinations for maximum compatibility with acids, bases and aromatic hydrocarbons. The seal operates without a purge or flush system and can be built with no elastomers, making it impervious to aggressive chemistries. Simple to install, the OFS uses external springs to maintain constant seal face pressure as components wear.

All MECO seals are custom-engineered to suit individual applications, providing an effective alternative to packed glands for sealing solids, liquids, vapors and gases on rotating equipment in many process industries.
