PROBLEM TO BE SOLVED: To provide a submerged disturbance pump in which supernatant water is positively introduced to dilute sludge and the like and either sludge or sand and the like are efficiently sucked up by some agitating vanes.SOLUTION: This invention relates to a submerged disturbance pump 10 comprising an impeller 14 arranged at an intermediate part of a rotating shaft 13 rotationally driven by a motor 12; an impeller casing 11 having a suction port 25 at a lower central side of the impeller 14 and a water discharging port 16 at a side part; a cylindrical pump side strainer 22 communicated with and connected to the lower part of the impeller casing 11 and provided with a plurality of suction ports 20 at a circumferential wall 19; a cylindrical body 27 for restricting agitation flow having its upper part connected to the lower part of the pump side strainer 22 through a partition plate 26 and having its lower part acting as an opening; and agitating vanes 30 which are partly or totally stored in the cylindrical body 27 for restricting agitation flow and attached to the lower part of the rotating shaft 13. The side part of the cylindrical body 27 for restricting agitation flow is provided with a conducting tube 40 for supplying water to the agitating vanes 30 and discharging it downwardly. |
