の自吸式ポンプ。[Scope of Claim for Utility Model Registration] 1. In a self-priming pump in which the discharge port leading to the steam/water separation chamber of the pump casing that houses the impeller is divided into a discharge passage and a return passage by a flow dividing wall, A self-priming pump characterized in that a slow flow plate having a plurality of small holes is disposed above the discharge passage. 2. A slow flow plate provided at the top of the discharge passage in the steam/water separation chamber has a hole that is made smaller toward the top of the discharge passage.
2. The self-priming pump according to claim 1, further comprising a small hole which becomes larger as it goes away from directly above the discharge passage.
