In a stern-tube seal a displacement pump (22) is arranged in a housing ring (53) at a chamber (14) for drawing off liquids which seep in or flow through the chamber, with the displacement element being driven by a cam (6) located on the shaft (1). The liquids are sucked in through a valve (21) and are discharged via a line (20) and a delivery valve (23) arranged in or close to the seal housing, for example into a further line (24) which rises upwardly and/or has a large flow resistance. <IMAGE> |
