Claims

[Scope of utility model registration request]

(1) The base can be fixed to the impeller shaft sleeve,
A seal ring having a pot portion on the outer periphery of a lip that can be curved and extended outward from the base is integrally molded from an elastic material,
The tip of the lip is configured so that it comes into close contact with the lower surface of the fixed ring fixed to the back casing when the pump is stopped or when internal pressure is applied, and does not come into contact when the pump is in operation. Shaft sealing device.

(2) Utility model registration claim No. 1 characterized in that when the pump is stopped, the elastic force of the lip of the seal ring causes the tip of the lip to come into close contact with the lower surface of the fixed ring. ) The shaft sealing device described in item 2.

(3) When the pump is in operation, centrifugal force is applied to the lip with the bowl part as the shaft rotates, and the tip of the lip is kept in a non-contact state with the fixed ring against the elastic force of the lip. A shaft sealing device according to claim (1) of the utility model registration, characterized in that it is configured so that:
