ンプ用メカニカルシール。[Claims for Utility Model Registration] (1) An outer cylinder having a first outer circumferential surface and a second outer circumferential surface, a seal ring formed of a carbon material and loosely fitted to the second outer circumferential surface, and a seal ring that corresponds to the seal ring. A mechanical seal for a water pump that has a floating seat in contact with the floating seat and a spring that biases the seal ring toward the floating seat via packing, the outer peripheral surface of the seal ring being coated with a resin that is more resistant to brittleness than the seal ring. A mechanical seal for water pumps characterized by being coated with. (2) The mechanical seal for a water pump according to claim 1, wherein the resin coating is formed of a resin having substantially the same thermal conductivity and coefficient of thermal expansion as the seal ring.
