1.Introduction of silicon carbide :
Silicon carbide is an inorganic non-metallic materials with high hardness, high wear resistance, low coefficient of friction, oxidation resistance, good thermal stability, low thermal expansion coefficient, thermal conductivity and thermal shock and great resistance to chemical corrosion, etc. excellent characteristics, can be used for a variety of requirements for abrasion, corrosion and high temperature mechanical equipment. Engineering and technical staff after years of unremitting efforts, has greatly improved the performance of silicon carbide. Now, silicon carbide has become an important engineering materials. Widely used in the field of machinery, metallurgy, petrochemical, shipbuilding, military equipment, etc., such as mechanical seal friction, plain bearings, nozzles, cutting tools, etc.

4.Applications of john crane mechanical seal :
• For plain shafts
• Single and dual seal
• Elastomer bellows rotating
• Unbalanced
• Eliminates damage to bellows
• Eliminates drive failure
Operating parameters
• Shaft diameter: d1 = 9.525 … 101.6 mm (0.375" ... 4")
• Pressure: Up to 10 bar (145 PSI),
• Temperature: t = -30 °C … +200 °C (-22 °F … +392 °F)
• Sliding velocity: vg = 13 m/s (2500 fpm)
• Admissible axial movement: ±2.0 mm
Advantages
• 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 and type of mating ring
applications
• Water and waste water technology • Food and beverage industry
• Pulp and paper industry • Water and waster water pumps
• Water, waste water, slurries (up to 5 % by weight) • Pulp (up to 4 % otro)
