To provide a pump with a flow detecting function capable of detecting a flow state in a flow passage while maintaining peristalsis type pump performance, and a pump abnormality detecting system.SOLUTION: A pump 1 with a flow detecting function includes a flow passage 10 having a flow passage wall 11 displaced in accordance with change in pressure of fluid flowing in an inside thereof, a pump 2 peristaltically moving the flow passage 10 by moving a plurality of pressure-contact pieces 22 coming in press-contact with the flow passage wall 11, and a pressure detector 3 having a pressure receiver 3b which is brought into contact with the flow passage wall 11 in a pressing region 100 in which the plurality of pressure-contact pieces 22 presses the flow passage wall 11 and at a position opposite across the plurality of the pressure-contact pieces 22 and the flow passage 10.SELECTED DRAWING: Figure 1 【課題】蠕動式のポンプ性能を維持したまま、流路内の流動状態を検知できる流動検知機能付きポンプ、ポンプ異常検知システムの提供。【解決手段】流動検知機能付きポンプ１は、内部を流れる流体の圧力変化によって変位する流壁１１を有する流路１０と、流壁１１に圧接する複数の圧接子２２を動かすことによって、流路１０を蠕動運動させるポンプ部２と、複数の圧接子２２が流壁１１を押圧する押圧範囲１００で、且つ、複数の圧接子２２と流路１０を挟んだ反対側の位置において、流壁１１に接触する受圧部３ｂを有する圧力検出部３と、を備える。【選択図】図１
