A question regarding the double-end face seal of mechanical pumps
Thread Content
What is the maximum temperature allowed for the external sealing fluid in the double-end face seal of mechanical pumps?
Add 50 to the freezing point of the transport medium; it should be several dozen degrees below the vaporization temperature of the outer sealing fluid – a moderate value is sufficient
We generally require that the temperature be at room level for the users, but the pressure must be stable and the area clean
The flushing fluid does not vaporize when it enters the sealed chamber
