With the DF(P)DGS6 EagleBurgmann offers reliable shaft sealing for API 610 high-performance pumps, e.g. BB3 and BB4 process pumps, and vertical pumps applied in liquefied gas fractionation, in pump stations of downstream NGL (Natural Gas Liquids) pipelines and also in CO2 applications.
Numerous plant operators experience problems incurred by temperature and pressure fluctuations in the pump. In conjunction with the low vapor pressure margin of the medium (e.g. ethane, propane), this can cause phase transitions between liquid and gas at the seal faces – they run dry. Conventional mechanical seals consequently sustain damages which results in seal failures.
