Sulzer ethane pumps which are applied in the pipeline of Enterprise Products Operating LP in Mont Belvieu, Texas, USA (picture above) have been sealed successfully by EagleBurgmann DF-DGS6/98-ZT1-U seals since July 2011. The DiamondFace bonded gas seals provide much longer operational life with very low leakage compared to the originally used liquid-lubricated seals.
Operating conditions: p = 40.7 … 50.3 barg (590 … 725 PSIG), t = -12.8 °C … +21.1 °C (+9 °F … +70 °F), n = 3,570 min-1.
A number of EagleBurgmann DGS6/49-TA1-U seals with DiamondFace bonding are applied in Schlumberger pumps in an US based ethane fractionation plant.
Operating conditions: p = 62.1 barg (900 PSIG), t = -6.7 °C … +150 °C (+19.9 °F … +302 °F), n = 3,550 min-1
EagleBurgmann DF-DGS6/98-ZT3-U seals are installed in Sulzer Pumps of a fractionation plant in Mont Belvieu, USA, which process mixes NGL streams into purity NGL products like ethane, propane etc.
Operating conditions: p = 44,1 ... 49,6 barg (640 … 720 PSIG), t = 18 °C ... 24 °C (64.4 °F ... 75.2 °F), n = 3,560 min-1
ITT Industries-Goulds pumps of an ethylene expansion plant in Bayport, Texas, USA are equipped with EagleBurgmann DF-DGS6/108-ZT2-U seals.
Operating conditions: p = 24.9 barg (374.9 PSIG), t = -24.3 °C … +10 °C (-11.7 °F … +50 °F), n = 3,600 min-1
