PROBLEM TO BE SOLVED: To surely prevent clogging of a stirring device, and to stably secure performance of the stirring device in a submerged pump device 2 with a stirring device 4 for ejecting at least a part of discharge flow of a submerged pump body into a water tank only for a prescribed time in operation start of the submerged pump body 3.SOLUTION: A path partitioned to allow discharge flow to flow to a prescribed main flow direction is formed in a pump device, and a branch hole 29 for allowing the discharge flow to flow in a branch direction branched from the middle position of the path and going from the pump device toward the stirring device is opened to a wall surface constituting the path, and the stirring device is connected to the branch hole. The submerged pump device further includes a foreign matter intrusion prevention member 711 arranged to close a part of an opening 29a of the branch hole and preventing intrusion of foreign matter into the stirring device. |
