This split seal is suited for a wide-variety of applications
MECO Seal
The OFS Type-1 fully split seal (photo) is especially suitable for vacuum, low-pressure and abrasive applications. The design tolerates both runout and thermal growth at moderate speeds. The OFS Type-1 places a single, hardened, stainless-steel rotary seal face, spring-loaded against a single, bearing-grade, polymeric stationary seal face. The seal does not require a barrier fluid. A wide selection of materials is available, allowing service in diverse processes. The OFS Type-1 split seal is ideal for top-entry agitators, crystallizers, dryers, pan mixers, blenders, hoppers and similar rotating equipment used in the petrochemical, plastics, metals, minerals and other process industries. The OFS Type-1 seal is used with top-entering and horizontal shafts. The seal has been used with crystallizers operating at cryogenic temperatures, and in an environment with saturated steam under full vacuum and relatively hot conditions. The seal is often used both to keep process materials inside the vessel and also to keep atmospheric oxygen from entering the vessel. Booth 2911 — MECO Seal, Georgetown, Maine
