Abstract: An objective is to enable the suppression of a repetition of the operation and stoppage of a pump by maintaining driving at the rated rpm, even when the water level on the side of an inlet is no more than the lowest water level at which total-amount drainage driving is possible. To achieve the objective, an axial line (311) of an output shaft (31) of an underwater pump (1) is placed to be inclined by a predetermined angle from horizontality such that an inlet (21) can become lower than an outlet (22). When the height from a bottom surface (102) of a waterway to an upper circumference (531) (a lower surface of a suction guide plate (511)) of an opening part (53) is Y1, and the height from the bottom surface (102) of the waterway to the bottom of an impeller (32) is Y3, Y3 is set to be located on a position higher than Y1. When a water level on the side of the inlet is lowered, air is suctioned from the opening part (53). As a result, water in a casing (2) of the underwater pump (1) rapidly falls, a flap valve (4) is closed by its self-load, and an air standby driving (a motor (3) continues a rotation operation state at the rated rpm), in which the impeller (32) is exposed to the air, is performed. There is little noise and vibration, and there is less pressure on the motor (3).
