99 5 pure aluminum oxide alumina is preferred.
Ceramic seal faces.
Ceramic seal faces have the property of good sealing properties resistant high temperature resistant corrosion and resistant wearing.
Ceramic cannot however handle the thermal shocks that ni resist or 17 4 seats can.
Ceramic seal rings is the best seal face material for highly corrosive chemical services we supply the high alumina ceramic materials.
Kemet lapping systems are used in both manufacturing and reconditioning processes.
Common types of mechanical seal face.
Stationary sealing members of buna epr.
Machine lapping is the production method of lapping mechanical seal faces.
Ceramic generally a 99 5 aluminum oxide offering excellent wear characteristics due to it s hardness.
Lower purity grades typically 85 are available but are more subject to chemical attack and thermal shock.
In general dissimilar materials are used for seal faces.
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.
The more common end or rotating face mechanical seal designs feature mating faces as the primary sealing elements.
Applications of mechanical seal faces.
Carbon ceramic silicon carbide or tungsten carbide may be considered.
For best results with double or tandem seals handling abrasive the inboard seal faces should be a hard material such as silicon carbide vs.
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.
It is chemically inert and can be applied to nearly any product.
If ceramic faces are not holding up and upgrade to silicon carbide which is in the same family of materials is a harder alternative.
Silicon carbide while the outboard seal faces should have maximum lubricity such as.
Combination of ceramic carbon graphite seal faces are ideal choice for leak proof maintenance free applications.
Look forward to your cooperation.
In evaluating materials for seal faces both the properties of the individual materials and the combination of the tribological pair must be considered.
Carbon tungsten carbide ceramic silicon carbide chrome oxide stellite ni resist and phosphor bronze.
At rcpl we manufacture mechanical seal faces in various sizes and compositions like ravituff 99 ravituff 95 eco alumina steatite and saz.
They provide longer life and greater operating safety.
