What exactly are the specifications for pressurized double-end mechanical seals API610? Back to back? In person again? Or what form? Please give me some advice!
Personally, I think a double-end mechanical seal should be face-to-face, as the flushing fluid coming from the pump outlet needs to be directed to the middle of the seal in order to flush the rotating ring.
It depends on the scheme you choose; different schemes have different arrangements for the seals. This is determined by the requirements of API682 for seals, while API610 applies to centrifugal pumps. If you opt for scheme 53 from API682, then in this scheme the liquid storage tanks are under pressure and their pressure is higher than that of the sealing chamber. Normally, the seals are arranged in series, face to face. In scheme 54 as well, there is pressure, and in such cases the seals are usually arranged back to back. In many situations, the choice depends on the medium, temperature, and the sealing chamber conditions. I am a specialist in sealing technology, and I make my decisions based on these factors. I hope this helps you
