Ceramic Mechanical Pump Seals

However when the service is abrasive the mechanical seal has to have hard seal faces that can hold up.

Ceramic mechanical pump seals.

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. The spring loaded design keeps the sealing surfaces in contact as the material wears. Once made with metal the most common seals faces used today in these pump seals are carbon and ceramic faces. Ceramic cannot however handle the thermal shocks that ni resist or 17 4 seats can.

Systems with high ph levels. Hard faces such as silicon carbide and tungsten carbide solve that problem. 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. Single spring mechanical pump seals multipule springs metal bellows in both in line and cartridge seals.

Most hvac applications maintain a ph from 7 0 to 9 0. The majority of seals used in pumps are typically carbon ceramic. 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. Ceramic generally a 99 5 aluminum oxide offering excellent wear characteristics due to it s hardness.

Help keep your pumps going strong with high quality pump shaft seals from grainger. Once in a while the ph is too high for the carbon ceramic seal material. 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.

Ceramic seal faces for mechanical seals engineered cartridge seals. Shop grainger today for dependable pump shaft seals in the size and material that can fit your application. It is chemically inert and can be applied to nearly any product. Mechanical characteristic ceramic material is the material with the best rigidity and highest hardness in engineering materials and its hardness is mostly above 1500hv.

Mechanical seals has the high demands about sealing materials so the ceramic is choosed to make ceramic mechanical seal because of its competitive features. A typical water application can last 20 years.
