排水用水中ポンプ。[Claims for Utility Model Registration] (1) In a submersible drainage pump equipped with a strainer connected to the lower end of the casing so as to be able to support the pump body, the lower end of the casing is located opposite to the upper end connecting part of the strainer. What is claimed is: 1. A submersible pump for drainage, comprising: an annular seat provided in the strainer; and an air passage provided in the annular seat so as to communicate between the inside and outside of the strainer. (2) The scope of the utility model registration claim, in which the outer surface of the lower end of the casing is formed into an inclined surface that becomes higher toward the outside from the lower end surface of the outer periphery of the suction port opening at the lower end toward the upper wall surface of the air passage. The submersible drainage pump described in item 1.
