取付けたことを特徴とする自吸式遠心ポンプ。 A pump impeller directly connected to the motor rotating shaft is housed in a volute casing, and a front casing is provided adjacent to the volute casing via a partition plate, and the inside of the front casing is divided into a suction side and a discharge side by a partition wall. In a self-priming centrifugal pump having a structure in which the suction side communicates with the volute casing through a suction hole formed in the partition plate, and the discharge side communicates with the volute casing through a discharge hole formed in the upper part of the partition plate, the front casing A through hole is provided in a partition wall that divides the interior into a suction side and a discharge side at a position higher than the pump impeller, and when the discharge side pressure in the front casing is higher than the suction side pressure, the through hole is inserted. A self-priming centrifugal pump featuring a flap valve that closes watertight.
