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