PROBLEM TO BE SOLVED: To provide a pump device capable of effectively preventing clogging of a foreign matter for a stationary blade to improve foreign matter passing performance. SOLUTION: A motor housing 14 of a submergible motor 3 is fixed through a plurality of stationary blades 16 in a cylindrical casing 2. This pump device is provided with a fixing and supporting stationary blade 16a in which the stationary blade 16 fixes the motor housing 14 with an interval between an inner peripheral face of the casing 2 and it and a non-supporting stationary blade 16b not supporting the motor housing 14 by a space passage 18 provided along the downstream side from the upstream side of water stream by rotation of an impeller 5 of the submergible motor 3.
