Ceramic Mechanical Pump Seals

Shop grainger today for dependable pump shaft seals in the size and material that can fit your application.

Ceramic mechanical pump seals.

Systems with high ph levels. Ceramic generally a 99 5 aluminum oxide offering excellent wear characteristics due to it s hardness. Ceramic cannot however handle the thermal shocks that ni resist or 17 4 seats can. Single spring mechanical pump seals multipule springs metal bellows in both in line and cartridge seals.

Mechanical seals has the high demands about sealing materials so the ceramic is choosed to make ceramic mechanical seal because of its competitive features. The majority of seals used in pumps are typically carbon ceramic. Most hvac applications maintain a ph from 7 0 to 9 0. Once in a while the ph is too high for the carbon ceramic seal material.

Find replacements for a wide range of pump shaft seals including a variety of crane us seal and sealol type seals. It is chemically inert and can be applied to nearly any product. 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. 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.

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. Help keep your pumps going strong with high quality pump shaft seals from grainger. 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 seal faces for mechanical seals engineered cartridge seals. Hard faces such as silicon carbide and tungsten carbide solve that problem. 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 more common end or rotating face mechanical seal designs feature mating faces as the primary sealing elements. 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.
