For centrifugal pumps, single-face mechanical seals must be replaced with double-face mechanical seals – specifications and requirements
Thread Content
I would like to ask the experts here: does anyone know the specifications and requirements regarding the need to replace single-face mechanical seals with double-face mechanical seals in centrifugal pumps used by refining companies? Please share relevant information so I can learn from it. Thank you!
The medium must not leak outside (toxic, flammable, etc.)
Experience with state-owned enterprises: Pumps whose medium temperature is above 250°C or whose operating temperature is above the ignition point of the medium, liquid hydrocarbon pumps, as well as pumps dealing with flammable, toxic, and hazardous media
