摘要： A seal apparatus, for sealing around a rotating shaft such as a propeller shaft of a watercraft between the exterior water and an interior lubricant space, includes a multiple seal arrangement with plural seal rings forming seal chambers therebetween, and plural fluid medium lines supplying and/or returning a respective fluid medium to a respective seal chamber. A section of a first medium line is formed as an axial passage through a housing of the apparatus, and a section of a second medium line is formed by a pipe arranged within the axial passage in the housing. A method of making such an apparatus especially by retrofitting an existing seal arrangement involves inserting a pipe into an axial passage in the housing in order to establish two medium lines through the housing where there was previously only one medium line.
