EagleBurgmann seal solves problems associated with pumping light vaporous media
E
agleBurgmann Germany GmbH & Co Kg has developed the DF-(P)DGS6 seal which, it says, can easily manage all states of highly vaporous media – gaseous and liquid, and evaporation – in the sealing gap. According to the company, the DF-(P)DGS6 enables it to offer reliable shaft sealing for API 610 high-performance pumps, for example, BB3 and BB4 process pumps, and vertical pumps used in liquefied gas fractionation, in pump stations for downstream natural gas liquids pipelines and also in CO2 applications.
The DiamondFace-bonded seal face of the DF-(P)DGS6 pump seal with bidirectional gas grooves.
Numerous plant operators experience problems caused by temperature and pressure fluctuations in pumps. In conjunction with the low vapour pressure margin of the medium (such as ethane or propane), this can cause phase transitions between liquid and gas at the seal faces – they run dry. Conventional mechanical seals consequently sustain damage which results in seal failures. The company developed this seal concept from dry gas seals technology for compressors. Because of the broad seal faces with bidirectional gas grooves the DF-(P)DGS6 runs contact-free when the media is gaseous. The use of EagleBurgmann’s DiamondFace bonding of the primary seal faces enables the seal to even run dry, but remain wear-free in transient conditions of the medium. If the medium is in liquid state the seal acts like a conventional liquid-lubricated mechanical seal. The company claims that more than 150 of these seals have been successfully deployed to date in the first installation of pumps or exchanged for poorly performing ones in this Continued on page 16...
