【実用新案登録請求の範囲】[Scope of utility model registration request] インペラが回転すると、該インペラ周辺の液に
遠心力を付与して、該インペラ周縁と該周縁を取
り囲む周辺部材の間の隙間に水膜シールを形成し

軸封装置によることなく防止するようにしたポン
プであつて、前記水膜シールを形成せしめる隙間
に面する或いは隣接する周辺部材分割面にガスケ
ツトを設けたポンプ。 When the impeller rotates, centrifugal force is applied to the liquid around the impeller, forming a water film seal in the gap between the impeller periphery and the peripheral member surrounding the periphery, thereby preventing outside air from entering from the impeller shaft penetration part. 2. A pump which prevents this without using a sliding shaft seal device, the pump having a gasket provided on a dividing surface of a peripheral member facing or adjacent to the gap in which the water film seal is formed.
