The present invention relates to a new kind of a mechanical seal, a so called slide ring seal, which is used, for example, for sealing a shaft space of a centrifugal pump in relation to a pumping space thereof. The present invention especially relates both to centering said mechanical seal and/or fastening said mechanical seal to the casing of said centrifugal pump and a body part used for the attachment. A characterizing feature of a mechanical seal in accordance with the present invention, comprising at least one rotary slide ring unit (24, 24′, 24″), a body part by means of which said seal is attached to said casing (16), and at least one either separate counter ring unit (42, 42′) or a counter ring unit (42, 42′) stationarily attached to said body part, is that said body part (40, 40′) is provided with inclined fastening means (52), by means of which the body part (40, 40′) is tightened to the casing both axially and radially. |
