Ceramic Seal Faces

Although the faces can be manufactured from a myriad of different materials one is typically carbon while the other is usually a hard material.

Ceramic seal faces.

Carbon tungsten carbide ceramic silicon carbide chrome oxide stellite ni resist and phosphor bronze. Ceramic seal faces have the property of good sealing properties resistant high temperature resistant corrosion and resistant wearing. 99 5 pure aluminum oxide alumina is preferred. Another group of seal faces would be those of coated seal faces.

It is chemically inert and can be applied to nearly any product. Lapping and polishing mechanical seal faces. Ceramic generally a 99 5 aluminum oxide offering excellent wear characteristics due to it s hardness. Seal face stationary seat secondary seals spring other metal parts except seal cover and shaft sleeve direction of rotation of the mechanical seal type n and k type c is also the spring winding direction r clockwise looking from the stationary seat toward the seal face looking from the drive side with the shaft.

Ceramic mating faces are used for water and general service applications including oil. Alox aluminum oxide ceramic tungsten carbide silicon carbide etc. Aus unserer langjähren eigenen erfahrung als anwender entwickeln und vertreiben wir nachhaltige und ressourcenschonende produkte für sie als anwender. Ceramic seal faces can last 20 years and are a very cost effective option.

Kemet lapping systems are used in both manufacturing and reconditioning processes. Carbon ceramic ni resist 17 4 silicon carbide tungsten carbide gfptfe glass filled ptfe. Face flatness the mechanical seal faces are obviously the most critical sealing point of a mechanical seal assembly. Since alumina exhibit high hardness good abrasion resistance good resistance to acid and mild alkaline solutions.

Machine lapping is the production method of lapping mechanical seal faces. The most common types of seal faces are. It is chemically inert and can be applied to nearly any product. Ceramic cannot however handle the thermal shocks don t drop them that ni resist or 17 4 seats can.

Ceramic is commonly used as a mating ring together with carbon graphite opposite seal face in mechanical seal kits which in turn used in chemical pump applications. Common types of mechanical seal face. The choice of seal face depends on the mechanical seal application. This makes them suitable choice for chemical seal faces.

They will shatter like a plate if dropped on concrete. Ceramic seal rings is the best seal face material for highly corrosive chemical services we supply the high alumina ceramic materials.
