type 21 mechanical seal price

The Type 21 is ideal for use in centrifugal, rotary and turbine pumps, compressors, chillers and other rotary shaft equipment. It is also commonly used by the wastewater and water systems industries for applications such as waste treatment, potable water and HVAC.

We recognize and understand the vital role of john crane type 21 mechanical seal in their application. With purposes including securely fastening components within systems, and contaminants prevention such as gases and liquids from navigating through enclosed and sealed areas. That is why we offer wholesale john crane type 21 mechanical seal in different variations and diversities to ensure the integrity and efficiency of systems they will be applied to will function successfully and optimally. The different seals" types available include static that does not move along with other seals and dynamic seals that move collaboratively.

Depending on the industry and selected purpose, we consider john crane type 21 mechanical seal requirements. Requirements are like pressure, that is pressure changes, to ensure they can withstand and do not deform by the sealed fluid, the load and how it can withstand deflection, dynamics such as the alignment and vibration, and temperature covering the environmental conditions and the heating arising from the friction of the seal operation and fluid movement.

The seals are either bolts, nuts, or washers. Seal bots are commonly used because of their benefits in being reusable, preventing fluids and contaminants from escaping even under high pressure. Nuts are essential on temperature withstanding and compatibility with screws, studs, and bolts, in addition to, easy installation. Moreover, washers can withstand high pressures and are compatible with other seals.

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.
