Silicon carbide while the outboard seal faces should have maximum lubricity such as.
Ceramic seal faces.
Ceramic seal faces have the property of good sealing properties resistant high temperature resistant corrosion and resistant wearing.
Ceramic generally a 99 5 aluminum oxide offering excellent wear characteristics due to it s hardness.
Ceramic seal rings is the best seal face material for highly corrosive chemical services we supply the high alumina ceramic materials.
In evaluating materials for seal faces both the properties of the individual materials and the combination of the tribological pair must be considered.
Look forward to your cooperation.

Machine lapping is the production method of lapping mechanical seal faces.
Carbon ceramic silicon carbide or tungsten carbide may be considered.
Stationary sealing members of buna epr.
If ceramic faces are not holding up and upgrade to silicon carbide which is in the same family of materials is a harder alternative.
Ceramic cannot however handle the thermal shocks that ni resist or 17 4 seats can.
Applications of mechanical seal faces.
99 5 pure aluminum oxide alumina is preferred.
They provide longer life and greater operating safety.
It is chemically inert and can be applied to nearly any product.
Kemet lapping systems are used in both manufacturing and reconditioning processes.
Product categories of ceramic seal faces we are specialized manufacturers from china ceramic seal faces ceramic mechanical seal faces suppliers factory wholesale high quality products of carbon ceramic seal faces r d and manufacturing we have the perfect after sales service and technical support.
Rings of ceramic carbide carbon or composites of these materials are lapped flat in the range of less than 1 micron on an axial end face.
Common types of mechanical seal face.
Carbon tungsten carbide ceramic silicon carbide chrome oxide stellite ni resist and phosphor bronze.
In general dissimilar materials are used for seal faces.
Combination of ceramic carbon graphite seal faces are ideal choice for leak proof maintenance free applications.
It is chemically inert and can be applied to nearly any product.
Lower purity grades typically 85 are available but are more subject to chemical attack and thermal shock.
At rcpl we manufacture mechanical seal faces in various sizes and compositions like ravituff 99 ravituff 95 eco alumina steatite and saz.
