Tungsten Carbide seal rings are widely used as seal faces in mechanical seals for pumps, compressors mixers and agitators found in oil refineries, petrochemical plants, fertilizer plants, breweries, mining , pulp mills, and the pharmaceutical industry. The seal-ring will be installed on the pump body and rotating axle, and forms through the end face of the rotating and static ring a liquid or gas seal. 

A stepped sealing ring (also known as a stepped sealing ring or multi lip sealing ring) is a specially designed sealing element that achieves more complex sealing requirements by adding stepped layers to the sealing lip or structure. Its core uses and advantages are as follows: the stepped structure of the sealing ring with steps forms multiple sealing barriers, sequentially blocking different directions of media (such as liquids, gases, dust), significantly improving sealing reliability. The sealing ring with steps can adjust the sealing force according to the pressure gradient for different heights of steps. The sealing ring with steps is suitable for reciprocating motion (such as cylinder rod), rotating motion (such as pump shaft) or static flange sealing, reducing friction and wear. The sealing ring with steps significantly improves the sealing performance under complex working conditions through multi-stage sealing, pressure adaptation, and anti eccentric load ability, especially suitable for industrial equipment with high pressure, multiple pollutants, or complex motion forms.
