<p>The present invention relates to a dynamic sealing system device for a submerged pump comprising at least one feed line running in towards the dynamic sealing system, with a first valve device arranged in the feed line and a second valve device arranged such that in an open position it opens a first bypass line that runs from a point on the feed line between the first valve device and the pump and a low-pressure source at the pump to reduce the pressure in a barrier fluid in the sealing system. The invention also comprises a method for reducing the barrier fluid pressure for a submerged pump.</p> |
