Liquid cannot be added after the cold pump with nitrogen purge is turned on

The mechanical seal of the Sulzer cryogenic pump is equipped with a nitrogen purge line; it is not possible to add seal fluid when the pump is operating normally. Is this reasonable? What caused it?

I didn’t understand how the question is phrased; it would be better to include a picture or diagram to facilitate discussion. Additionally, if the operation methods and control conditions specified in the user manual are all within the acceptable range, it is advisable to consult the equipment manufacturer.

Are you referring to the sealed 53A or 53B solution?
