徴とする立軸ポンプ。 An impeller is disposed above a specific part of the pump that corresponds to the minimum water level below which air will be sucked in if the submerged water level of the suction bell mouth is below this level, and the tip of the suction bell mouth is brought to the minimum water level. On the other hand, a connecting tube is provided between the impeller and the suction bell mouth so as to be placed in a position where it is submerged in water as much as necessary, and an air passage whose inlet opens at the lowest water level is connected to this connecting tube. A vertical shaft pump characterized in that a communication passage with a small cross section is formed at a predetermined position above the inlet of the passage to communicate the intake passage with the outside.
