Claims

[Scope of utility model registration request]

The driven ring, which is airtightly supported on the inner periphery of the housing through an O-ring or other packing, and the seat ring, which is airtightly supported on the outer periphery of the shaft through an O-ring or other packing, slide closely against each other, and the slurry In the stationary mechanical seal for sealing a liquid to be sealed containing a liquid to be sealed, a lip seal is fitted onto the inner peripheral surface of the housing so as to be located in a space on the side of the liquid to be sealed of the packing between the housing and the driven ring. , between the tip of the inner lip of the lip seal and the outer circumferential surface of the driven ring,
A slurry-resistant mechanical seal characterized by having an extremely small gap smaller than the size of slurry particles in the liquid to be sealed.
