Mechanical seals are a factor that has a decisive effect on the cost-effectiveness of your operation. Because their wear determines the productivity of the entire system, whether it is a pump, agitator or compressor. What causes damage to the seal faces? One reason is dry running which is often unavoidable due to insufficient lubriion or when gas-lubried seal faces get in contact.
End-face mechanical seal - Wikipedia
An end-face mechanical seal, or a mechanical end-face seal, also referred to as a mechanical face seal but usually simply as a mechanical seal, is a type of seal utilised in rotating equipment, such as pumps, mixers, blowers, and compressors.When a pump operates, the liquid could leak out of the pump between the rotating shaft and the stationary pump casing.

Jul 17, 2017· The silicon carbide seal can handle 60 times the dissolved solid content and double the undissolved solids content with 20 ppm silica content thrown in for good measure. Why not just always specify EPR/SiC/SiC seals? There are two reasons: cost and lead-time. This seal will cost three times as much as the standard seal.
Carbon Graphite Mechanical Seal Types
Carbon graphite materials are widely used for these dynamic mechanical seals and are compatible with all mating faces including metals such as stainless steel, tungsten carbide, alumina, reaction bonded silicon carbide and self-sintered silicon carbide.
Engineered for appliions typical with mineral and ore
Primary seal faces are the same as the single SLM-6000 but are placed in a tandem arrangement along with a low pressure secondary seal having carbon vs. silicon carbide faces. The secondary seal is engineered to last longer than a QCD when a fluid quench is applied. It can also allow operation of a closed loop fluid system when the secondary
