John crane mechanical seal TYPE 21 is designed for centrifugal, rotary and turbine pumps, compressors, chillers and other rotary shaft equipment. Now this type 21 mechanical seal has become a general industry standard in mechanical seal field.

Carbon and silicon are 2 kind of popular material for the rotary and stationary seal ring, if in big quantity, in order to reduce the cost, people choose ceramic as the seal material.

For the secondary seal, NBR is a low cost material, and for some hard material like hot oil, chemical medium, epdm or viton are better choice.

Lepu seal factory had been a leading manufacturer in the past years, and we manufacture the john crane mechanical seal type 21 with stable and high quality, buy this mechanical seal type 21 from our seal factory is a reliable choice.
