PROBLEM TO BE SOLVED: To provide a low flow rate high lift type centrifugal pump.SOLUTION: A sequential flow type centrifugal pump is provided in which an inner circumferential portion of a housing 3 includes a plurality of flow-in flow passages 6 and an outer circumferential portion of the housing 3 includes flow-out flow passages 7 of the same number of the flow-in flow passages. The pump includes: one impeller 4 having a part that applies a centrifugal force to liquid and that is rotated between the flow-in flow passage 6 and the flow-out flow passage 7 and a passage 8 through which liquid flowed in from the flow-in passages 6 and driven out to the flow-out flow passages 7 flows into another flow-in flow passage.COPYRIGHT: (C)2015,JPO&INPIT【課題】 低流量高揚程型の遠心ポンプを提供する。【解決手段】 ハウジング3の内周部分に複数の流入流路6と、ハウジング3の外周部分に流入流路と同数の流出流路7を備え、液体に遠心力を付与する部分が流入流路6と流出流路7の間で回転する1枚の羽根車4と、流入流路6から流入して羽根車4により流出流路7に駆出された液体が別の流入流路に流入する通路8を持つことを特徴とするシーケンシャルフロー型遠心ポンプを提供する。【選択図】図2
