Mechanical face seals

General information

Mechanical face seals are used for sealing the shafts of pumps and other devices, the working medium of which is oil, oil products, liquefied hydrocarbon gases, water, neutral liquids and liquids containing harmful and abrasive substances, reagents, these are substances of 2, 3, 4 hazard classes according to GOST 12.1.007-76.

The minimum number of elastic sealing joints, improved dimensional characteristics and high tightness of PAG mechanical face seals, significantly increase the overall reliability and operability of the device.

Symbol structure:

An example of a symbol for a spring-loaded single mechanical face seal installed on shaft 110, strapping according to API Plan02, second modification: PAG UTP.02-110-S8VKS.2

Mechanical face seals of the C.52 and P.52 series are used in units, the working medium of which is poisonous, toxic, corrosive, explosive and flammable liquids. Its use allows to exclude the penetration of the barrier liquid into the sealing medium.
