The MECO OFS Type-1 seal is frequently the best, fully-split seal 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, synthetic stationary seal face. The seal does not require a barrier fluid. A wide selection of materials is available, allowing service in diverse process materials. In aftermarket applications, the fully-split seal can be custom-designed for existing process equipment or can be tailored to new, specific, OEM applications.
The OFS Type-1 split seal is designed 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 seal is often used both to keep process materials inside the vessel and also to keep atmospheric oxygen from entering the vessel. The OFS Type-1 is used in the production of plastic resins and additives, paraxylene, solvent-based ink, VOC vapors and fumes, crystal sugar, industrial chemicals and industrial fermentation processes. Process improvements encompass product and atmosphere containment, product purity, batch time reduction and consistency between batches, extended mean-time-to-repair (MTR), and only two to four hours of installation time once the equipment is prepared. The fully-split assemblies meet chemical compatibility and materials of construction challenges.
The OFS Type-1 replaces stuffing boxes, lip seal housings, hard-face mechanical seals, elastomer-driven seals and unsplit seals. The split seal housing is fitted to your equipment, complete with a split, bearing-grade, synthetic stationary seal face.
