The present invention relates to a pumping action type underwater pump which improves suction force and discharge force by volumetric pumping action by a virtual piston formed by reciprocating motion of a pumping rotary body along with transfer by rotation of the pumping rotary body. In other words, the pumping action type underwater pump of the present invention comprises a pumping driving unit which forms the pumping rotary body by any one among an impeller and a screw, vertically arranges a pump housing, a driving part, and the pumping rotary body, arranges the pumping rotary body on the lowest side, and forms the virtual piston that performs the volumetric pumping action by the reciprocating motion of the pumping rotary body. Therefore, according to the present invention, by means of the pumping driving unit which forms the virtual piston that performs the volumetric pumping action by the reciprocating motion of the pumping rotary body formed by the impeller or the screw, the volumetric ...
