TYPE 21 Elastomer Bellows Seal A B C D E F – Face/Primary Ring – Seat/Mating Ring – Spring – Retainer – Elastomer Bellows – Drive Band Product Description The Type 21, a general purpose seal, has become an industry standard with OEM designers. Made of stainless steel, it provides a service range well beyond that which is possible with comparably priced seals of other metallurgical construction. I The positive static seal between the bellows and the shaft, along with the free movement of the bellows, means that there is no sliding action that could lead to shaft damage by fretting. This ensures that the seal will automatically compensate for normal shaft run-out and axial movements. This versatile seal can be used on a wide range of equipment including centrifugal, rotary and turbine pumps, compressors, mixers, blenders, chillers, agitators, and other rotary shaft equipment. Ideal for pulp and paper, pool & spa, water, food processing, wastewater treatment, and other general applications. Temperature: -40˚F to 400°F/-40˚C to 205°C (depending on materials used) Speed: Up to 2500 fpm/13 m/ s (depending on configuration and shaft size) Self-aligning unit automatically adjusts for shaft end play and run-out. Eliminates potential shaft fretting damage between the seal and shaft. Positive mechanical drive protects the elastomer bellows from overstressing. Single coil spring improves tolerance to clogging. Simple to fit and completely field repairable. Can be used with practically any type of mating ring.
