摘要：

The present invention relates to a sealing arrangement for sealing the end of a rotating cylindrical member, such as a shaft or a drum, in the filters or washers of the wood processing industry in relation to the outer shell or other component of the filter or washer surrounding said member. The sealing comprises a stationary ring-shaped plate (141) located essentially concentrically with said cylindrical member (118) in a distance from the end surface of (119) of the cylindrical member, in which ring-shaped plate there are preferably fitted at least two sealing rings (143' and 143'') having different diameters and a propelling member (153) corresponding to each ring. A pressure medium flow is directed to the propelling member so that by means of said propelling member the sealing rings (143' and 143'') are protruded outwards from the stationary ring-shaped plate in the axial direction and pressed against the plane end surface of the rotating cylindrical member (119) for effecting the sealing.
