These materials are frequently thought of as the soft face and the hard face although sometimes two hard faces are used.
Ceramic seal faces.
Applications of mechanical seal faces.
They provide longer life and greater operating safety.
In evaluating materials for seal faces both the properties of the individual materials and the combination of the tribological pair must be considered.
Ceramic seal rings is the best seal face material for highly corrosive chemical services we supply the high alumina ceramic materials.
Combination of ceramic carbon graphite seal faces are ideal choice for leak proof maintenance free applications.
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.
Kylin ky seals is currently selling mechanical seals elastomer bellow mechanical seals o ring mechanical seals ptfe wedge mechanical seals teflon bellow mechanical seals metal bellow mechanical seals cartridge mechanical seals etc seal faces silicon carbide seal faces reaction bonded silicon carbide sintered silicon carbide sintered silicon carbide with graphite reaction bonded.
99 5 pure aluminum oxide alumina is preferred.
It is chemically inert and can be applied to nearly any product.
Look forward to your cooperation.
In general dissimilar materials are used for seal faces.
Common types of mechanical seal face.
Carbon tungsten carbide ceramic silicon carbide chrome oxide stellite ni resist and phosphor bronze.
Ceramic generally a 99 5 aluminum oxide offering excellent wear characteristics due to it s hardness.
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.
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.
Silicon carbide while the outboard seal faces should have maximum lubricity such as.
Carbon ceramic silicon carbide or tungsten carbide may be considered.
If ceramic faces are not holding up and upgrade to silicon carbide which is in the same family of materials is a harder alternative.
It is chemically inert and can be applied to nearly any product.
For best results with double or tandem seals handling abrasive the inboard seal faces should be a hard material such as silicon carbide vs.
Machine lapping is the production method of lapping mechanical seal faces.
Ceramic seal faces have the property of good sealing properties resistant high temperature resistant corrosion and resistant wearing.
The more common end or rotating face mechanical seal designs feature mating faces as the primary sealing elements.
