Abstract
The invention relates to a marine meachanical seal arrangement comprising a first mechanical seal () comprising a first rotating slide ring () and a second stationary slide ring () defining a first sealing gap () between their two sliding surfaces (), a second meachanical seal () comprising a second rotating slide ring () and a second stationary slide ring (), which define a second sealing gap () between their sliding surfaces (), a barrier circuit () comprising a barrier fluid cavity () which is arranged between the first mechanical seal () and the second mechanical seal () and is filled with a barrier fluid, the barrier fluid cavity () being divided into a first sub-cavity () and a second sub-cavity (), the first subcavity () and the second subcavity () being separated by a flexible lip seal () wherein the second sub-cavity () is arranged at the second mechanical seal (), and wherein the lip seal () is arranged such that a flow of barrier fluid from the first subcavity () into the second subcavity () is allowed and a flow of barrier fluid from the second subcavity to the first subcavity is prevented.
