ルシール。 An annular projection protruding in the axial direction is formed on the end surface of the seal cover that is fitted to the shaft of the slurry pump, a rubber spring is fitted to the inner diameter side of the annular projection, and the shaft is rotated by the rubber spring. In an internal flow type mechanical seal in which a side seal ring is fitted and a front end of the rotating side seal ring that faces a non-rotating side seal ring projects in the axial direction from a front end of the annular protrusion, the annular protrusion substantially the entire inner diameter surface of the rubber spring is used as a joint surface for the rubber spring to regulate its protrusion length, and if necessary, a tapered surface is formed at the tip of the annular projection to promote circulation of the slurry liquid as the liquid to be sealed. A mechanical seal for slurry pumps featuring:
