ルシール。 The slurry fluid region and the higher-pressure sealed liquid region are separated by the relative rotational sliding action between the rotating sealing ring fitted and fixed on the rotating shaft side and the stationary sealing ring fitted and held on the casing side via an O-ring. In the mechanical seal configured to provide a shielding seal, an annular groove in which the O-ring is movably loaded in the axial direction is formed on the casing side, and an annular groove is formed on the side wall surface of the annular groove on the slurry fluid region side. A mechanical seal for slurry fluid characterized by forming a cleaning fluid jetting passage that opens in a pressure receiving recess.
