Numerous plant operators experience problems incurred by temperature and pressure fluctuations in the pump. In conjunction with the low vapour pressure margin of the medium (e.g. ethane, propane), this can cause phase transitions between liquid and gas at the seal faces, causing them to run dry. Conventional mechanical seals consequently sustain damage, which results... [Read More]
