Ceramic Mechanical Pump Seals

In most applications carbon ceramic seals work fine but there are certain circumstances when a different type of material for the mechanical seal should be specified.

Ceramic mechanical pump seals.

Systems with high ph levels. The majority of seals used in pumps are typically carbon ceramic. The more common end or rotating face mechanical seal designs feature mating faces as the primary sealing elements. However when the service is abrasive the mechanical seal has to have hard seal faces that can hold up.

Mechanical characteristic ceramic material is the material with the best rigidity and highest hardness in engineering materials and its hardness is mostly above 1500hv.

Ceramic cannot however handle the thermal shocks that ni resist or 17 4 seats can. 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. High speed mechanical pump shaft seals built for high speed circulation and dispensing pumps these seals have a short spring that facilitates speeds up to 10 000 rpm. Once made with metal the most common seals faces used today in these pump seals are carbon and ceramic faces.
