PROBLEM TO BE SOLVED: To provide a reversible pump capable of delivering the water sucked from one of two suction ports to one discharge port in accordance with the forward and backward operating direction of the pump. SOLUTION: A motor part 10 and a pump part 50 are integrated, a rotor 18 having a magnetic member 20 on an inner periphery of a stator 30 is rotatably mounted at the motor part 10, the rotor 18 has an impeller 23 having a blade 21 for forward rotation and a blade 22 for backward rotation, and has two suction ports 11, 13 continued from the pump part 40 and the discharge port 15 continued from the pump part 50, and the pump part 50 delivers the fluid sucked from the first suction port 11 to the discharge port 15 in the forward rotation of the impeller 23, and delivers the fluid sucked from the second suction port 13 to the discharge port 15 in the backward rotation of the impeller.
