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. Ceramic seal faces for mechanical seals engineered cartridge seals. The majority of seals used in pumps are typically carbon ceramic. Mechanical seals has the high demands about sealing materials so the ceramic is choosed to make ceramic mechanical seal because of its competitive features.

Shop grainger today for dependable pump shaft seals in the size and material that can fit your application. 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. Once made with metal the most common seals faces used today in these pump seals are carbon and ceramic faces. 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.

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. Mechanical characteristic ceramic material is the material with the best rigidity and highest hardness in engineering materials and its hardness is mostly above 1500hv. The more common end or rotating face mechanical seal designs feature mating faces as the primary sealing elements. It is chemically inert and can be applied to nearly any product.

Ceramic generally a 99 5 aluminum oxide offering excellent wear characteristics due to it s hardness. These seals work well with the temperatures mentioned above and a ph neutral range of 7 0 9 0. Once in a while the ph is too high for the carbon ceramic seal material. Help keep your pumps going strong with high quality pump shaft seals from grainger.

Find replacements for a wide range of pump shaft seals including a variety of crane us seal and sealol type seals. 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. Systems with high ph levels.

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. Single spring mechanical pump seals multipule springs metal bellows in both in line and cartridge seals.
