Advantages
The profen standard gas seal for pressures up to 100 bar (1,450 PSI). Due to simple components a reliable and economical solution for low pressure applications.
Application single seal: The simplest seal is a Dry Gas Seal in single arrangement. This seal is used in case that due to the nature of the product gas no additional back up seal is required. Separation seals as labyrinths, radial clearance seals or CobaSeal® are optionally available. This version is used as an emission-free arrangement with a corresponding flare/vent connection. Primary leakage is then discharged with the separating gas to the flare/vent. In the case of dirty gases the gas to be sealed has to be filtered in addition and conveyed to the seal chamber via connection "A". The resulting gas flow from the sealing compartment prevents any dirty/wet gas gas entering the seal.
