Claims

[Scope of utility model registration request]

(1) The sealing material of the mechanical seal placed on the shaft and installed on the casing side, and the sheet material placed on the shaft and installed at the inner end of the impeller, or both or one of them. A water pump, characterized in that a portion for receiving water flowing through the pump is provided on the contact surface between the sheet material and the sealing material when the sheet material rotates together with the impeller to enable water supply.

(2) The water pump according to claim 1, wherein the portion that receives water flowing inside the pump is formed by forming a peripheral wall of a sealing material or sheet material into a corrugated structure.

(3) The water pump according to item 1 of the Utility Model Registration Claim, wherein the portion that receives the water flowing inside the pump is an axial groove formed on the outer peripheral surface of the sealing material or sheet material.

(4) The water pump according to claim 1, wherein the portion that receives the water flowing inside the pump is a notch formed in the contact side shoulder of the sealing material or sheet material.

(5) The water pump according to claim 1, wherein the portion that receives the water flowing inside the pump is formed by making the outer circumferential surface of the sealing material or the sheet material into an elliptical shape.

(6) The water pump according to claim 1, wherein the portion receiving the water flowing inside the pump is a recess formed in the contact end surface of the sealing material or sheet material.
