Selection of pump mechanical seals for acrylic acid
Thread Content
The medium being transported is acrylic. Which material is more durable for the end faces of the mechanical seal, and which one is better for the O-rings? Is a double-end face design necessary for the mechanical seal? If a double-end face design is used and cooled with water, could this lead to excessively low temperatures that cause the internal medium to polymerize? Seeking answers to these questions
O-rings made of fluororubber cannot be used; they can be replaced with tetrafluoroelastomer rings or perfluoroether rings； The double-end face mechanical seal must be equipped with a flushing system and insulation. .
The sealed end cover is insulated, and the O-ring is made of perfluoroether
What does it mean by a sealed end cover with insulation? Is it to preserve the flushing fluid?
