Abstract
A seal arrangement for rotating shafts, in particular a propeller shaft of a ship which is in contact with water containing impurities, is designed to provide a filter portion substantially adjacent the outermost seal to thereby filter dirt particles out of the water and keep the dirt particles out of the vicinity of the seal. Such a filter can be made from a sintered material and can essentially be designed to fit the existing space available along the propeller shaft.
