Provided is a pumping apparatus which comprises: a main pump having an inlet part and an outlet part, and having a rotor mounted therein and able to rotate; an actuation generating part connected to the rotor and generating a rotational actuating force for rotating the rotor; a lubricant control feeding part installed to be connected to the main pump and selectively feeding a lubricant to the inside of the inlet part according to whether or not a fluid flows through the inlet part; and an actuation control part installed to be connected to the main pump and the actuation generating part, and controlling the rotational actuation of the rotor by selectively connecting the actuation generating part and the rotor according to the pressure volume of the fluid at the outlet part. The pumping apparatus according to the present invention has the lubricant control feeding part which selectively and automatically feeds the lubricant to the inside of the inlet part according to whether or not the fluid flows through the inlet part of the main pump. The actuation control part automatically controls the actuation of the rotor by selectively connecting the actuation generating part and the rotor according to the pressure volume of the fluid at the outlet part of the main pump. |
