Dilling Centrifugal Ceramic Pump Seal , Ceramic Seal Rings
Corrosion Wear Resistant
Zirconia ceramics mechanical seal rings are used in drilling
and completions equipment to extend the life of crucial components.
A sophisticated hybrid design of Ceramic/metal composites overcome
the tensile strength of the ceramics. Another example is the
application in axial tilt bearings which operate at very high load
in muddy and abrasive environments.
Ceramic features
1.High Hardness good wear resistance
2.High precision
3.Good mechanical strength
4.High temperature and chemical resistance
5.Electric insulation
6.Low thermal expansion
7.Smooth surface finish for low friction
8.Thermal Shock Resistance
9. Electrical insulating material.
