For an immersed pump having a suction port directly immersed in a liquid for operation, the present invention provides a pump that eliminates the need to seal a rotating shaft with a shaft sealing apparatus and that reduces the effect on individual pump sections of a) the thrust of the rotating shaft effected by the rotation of an impeller and b) the weight of a motor acting in the same direction, thereby preventing defects in the pump.To achieve this object, this invention provides an immersed pump configured in such a way that an impeller 7 is driven and rotated by a motor 2 to draw a liquid from a suction port 4A into a pump housing 3A and eject it from an ejection port 5. The suction port 4A is provided at the lower end of a body frame 1 or on the outer circumference of the upper end of the housing 3A, while the ejection port 5 is provided at the lower end of the housing 3A.
