A cassette-type seal, in which the outer ring (3) and the inner ring (11) are of oppositively directed angular profile and together enclose an annular space (5) which is essentially rectangular in side cross section. The space (5) is defined relative to the area that is to be sealed off by an outwardly extending flange (8) on the inner ring (11) which rotates with the shaft to be sealed. The gap remaining between the flange (8) and the outer ring (3) has its cross section extended by segmenting cuts distributed equally about the periphery, and through which liquid contained in the annular space (5) is constantly renewed under operating conditions.
