C50 Series Rotary low temperature bellows mechanical seal

Short Description:

C50 series seals to DIN24960/LIK and GB6556/LIK dimensions. Suitable for any DIN24960 and GB6556 standard centrifugal pump and similar mechanical rotary shaft seal.
The excellent dynamic performance and extensive environmental use of the C50 series seal are all derived from advanced welded metal bellows. The arch ripple with inclination of more than 45° on the inner edge greatly reduces the stress peak and decomsolves the welding stress of the inner hole, so that the stress distribution is more ideal and the elasticity is better. To ensure that the bellows seal has a good following.
C50 series can be matched according to different use requirements, according to the sealing allowable materials, can be adapted to different environment needs.
The C50 series seal is a typical bellows seal with simple structure and easy installation. Can meet the petrification. Oil refining, chemical, chemical fiber, food, medicine, thermoelectric and other different industries of different requirements, used for sealing and cleaning or particles of medium and low viscosity media. It is the best choice to solve toxic, corrosive and other problems.
