Ceramic Mechanical Pump Seals

The mechanical seals provided by bell and gossett have stainless steel metals buna elastomers a 99 5 pure aluminum oxide ceramic stationary seal face and a carbon rotating face.

Ceramic mechanical pump seals.

However when the service is abrasive the mechanical seal has to have hard seal faces that can hold up. A typical water application can last 20 years. The majority of seals used in pumps are typically carbon ceramic. Mechanical characteristic ceramic material is the material with the best rigidity and highest hardness in engineering materials and its hardness is mostly above 1500hv.

It is chemically inert and can be applied to nearly any product. Mechanical seals has the high demands about sealing materials so the ceramic is choosed to make ceramic mechanical seal because of its competitive features. Hard faces such as silicon carbide and tungsten carbide solve that problem. Once in a while the ph is too high for the carbon ceramic seal material.

Ceramic seal faces for mechanical seals engineered cartridge seals. Find replacements for a wide range of pump shaft seals including a variety of crane us seal and sealol type seals. Ceramic generally a 99 5 aluminum oxide offering excellent wear characteristics due to it s hardness. Systems with high ph levels.

Once made with metal the most common seals faces used today in these pump seals are carbon and ceramic 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. Most hvac applications maintain a ph from 7 0 to 9 0. Ceramic cannot however handle the thermal shocks that ni resist or 17 4 seats can.

Shop grainger today for dependable pump shaft seals in the size and material that can fit your application. 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. These seals work well with the temperatures mentioned above and a ph neutral range of 7 0 9 0. The spring loaded design keeps the sealing surfaces in contact as the material wears.
