PROBLEM TO BE SOLVED: To obtain a vortex flow type pump unit which is inexpensive and achieves excellent durability and low noise.SOLUTION: In a vortex flow type pump unit, a rotary shaft of an electric motor penetrates through a synthetic resin-made casing and is fastened to a shaft sealing device and an impeller in a written order. Further, a casing cover is fastened to the casing through an O ring in a water-tight state so as to cover the impeller. The vortex flow type pump unit conducts vortex flow pump action by rotation of the rotary shaft. The vortex flow type pump unit includes an inner ring integrally including a division wall body, which separates the suction side of the synthetic resin-made casing from the discharge side, and a liner body including a liner surface. The inner ring is formed by an elastic material. The inner ring is fastened to the synthetic resin-made casing.SELECTED DRAWING: Figure 3 【課題】安価で耐久性に優れかつ、低騒音の渦流れ形ポンプ装置を得る。【解決手段】電動機の回転軸が合成樹脂製ケーシングを貫通し、軸封装置、羽根車の順で固着され、羽根車を覆うようにケーシングカバーがＯリングを介して水密に固着されて、回転軸の回転により渦流れポンプ作用を行う渦流れ形ポンプ装置において、前記合成樹脂製ケーシングの吸い込み側と吐き出し側を分離する隔壁体と、ライナー面を備えるライナー体と、を一体に有するインナーリングを有し、該インナーリングは、弾力性を有する材料からなり、前記インナーリングを、前記合成樹脂製ケーシングに固着した。【選択図】図３
