PROBLEM TO BE SOLVED: To provide a reversible pump which can reduce the size and the cost thereof and improve the pump performance. SOLUTION: A motor unit 10 having a water intake port 11 and a pump unit 50 having two discharge ports 51 and 52 are integrated with each other. In the motor unit 10, a rotor 20 having a magnetic body 23 on the inner circumference of a stator 12 is rotatably disposed around a spindle 21, and a water flow passage 13 from the water intake port 11 is provided in the vicinity of the axis of the rotor 20. In the pump unit 50, the fluid fed from the water flow passage 13 is fed to the first discharge port 51 through a first discharge groove when an impeller 24 provided on the rotor 50 is driven normally. The fluid fed from the water flow passage is fed to the second discharge port through a second discharge groove when the impeller 24 is driven in a reverse direction.
