The invention discloses a pumping water machine body structure. The pumping water machine body structure comprises a body, an inlet part formed on one side of the body, a side outlet part formed at the other side of the body, a top outlet part formed at the top side of the body, an assembling seat formed on the front side of the body, a water outlet chamber, a sealing cover assembly and a communication assembly, wherein the water outlet chamber is arranged in the center of the assembling seat and communicates with the inlet part, the side outlet part and the top outlet part, the sealing coverassembly is used for closing the side outlet part or the top outlet part, and the communication assembly is connected with the other outlet part. According to the pumping water machine body structure,the two outlet parts are arranged which both communicate with the water outlet chamber, and then one outlet part is closed according to the condition so that water can be sent out from the other outlet part, in this way, a pipeline which is used for guiding the outlet part to the side which is convenient to connect does not need to be additionally designed, and the structure is not limited to a site and space and is convenient to install.
