Ceramic Mechanical Pump 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.

Ceramic mechanical pump seals.

Single spring mechanical pump seals multipule springs metal bellows in both in line and cartridge seals. The more common end or rotating face mechanical seal designs feature mating faces as the primary sealing elements. Once made with metal the most common seals faces used today in these pump seals are carbon and ceramic faces. The majority of seals used in pumps are typically carbon ceramic.

Ceramic generally a 99 5 aluminum oxide offering excellent wear characteristics due to it s hardness. A typical water application can last 20 years. Most hvac applications maintain a ph from 7 0 to 9 0. The spring loaded design keeps the sealing surfaces in contact as the material wears.

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. However when the service is abrasive the mechanical seal has to have hard seal faces that can hold up. Find replacements for a wide range of pump shaft seals including a variety of crane us seal and sealol type seals. Mechanical characteristic ceramic material is the material with the best rigidity and highest hardness in engineering materials and its hardness is mostly above 1500hv.

Hard faces such as silicon carbide and tungsten carbide solve that problem. 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. Zodiac r0479400 new style ceramic and carbon mechanical shaft seal replacement for select zodiac jandy pool and spa pumps 4 5 out of 5 stars 51 17 40 17. Once in a while the ph is too high for the carbon ceramic seal material.

Systems with high ph levels. It is chemically inert and can be applied to nearly any product. Shop grainger today for dependable pump shaft seals in the size and material that can fit your application. Ceramic cannot however handle the thermal shocks that ni resist or 17 4 seats can.

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. Help keep your pumps going strong with high quality pump shaft seals from grainger.
