How to deal with minor leakage in a dry gas seal pump
Thread Content
One of our centrifugal pumps is equipped with a dry gas seal, and it has been experiencing slight leakage recently. The pressure of the dry gas entering the pump is 5 kilograms, and the dry gas outlet is connected to a flare system from where it is continuously discharged; the pressure there is 4 kilograms. The medium transported by the pump is liquefied gas, and when there is a slight leak, the pressure at the dry gas outlet fluctuates. I would like to ask for advice on how to deal with this issue

If the pressure rises very quickly, it indicates a severe seal leakage; if the pressure rises slowly, it is recommended to continue monitoring the operation.
