Regarding the machine seal model
Thread Content
I encountered a mechanical seal with the model number BSTXX. There are various explanations for this: 1 is that it has a bellows in the mechanical seal; 2 is that it’s a mechanical seal without a bellows. But his flushing protocol is 11 plus 52. And why would a single-machine seal use scheme 52? Could someone please explain this? Thank you.
API682 2004 and API610 2004, Plan11+Plan52 represent the combination of these two types of mechanical seals
:Lol, well API610 specifies the code that should be used; I checked it again and was told that the code written wasn’t correct. It’s really ridiculous: Lol, it’s already been fixed
First: Balanced (B) or Unbalanced (U)； Second: single-end face (S) or pressurized double-end face (D) or unpressurized double-end face (T) ； Third: Seal gland type, standard type (P), throttle bushing type (T), auxiliary sealing device (A) ； Fourth: Gasket material; X indicates compliance with the manufacturer’s standards ； Fifth: Sealing end face material; X indicates compliance with the manufacturer’s standards.
