The utility model discloses a gas-liquid mixed transportation impeller and a gas-liquid mixed transportation centrifugal pump, belongs to the technical field of centrifugal pumps, and solves the problems that at present, after a gas-liquid mixed transportation medium enters the impeller, gas is easily gathered in the impeller, so that the impeller is blocked, and even the pump stops working. And the rear cover plate is fixed on the hub. And the plurality of blades are fixed on the rear cover plate at equal intervals. A plurality of first pressure guiding holes are formed in the position, close to the hub, of the rear cover plate, and a pressure guiding channel is formed in the corresponding position of the pump cover so that high-pressure liquid of the impeller outlet can be guided into the impeller inlet. Each blade is provided with at least one fracture, and the fractures are located at the positions, where gas is prone to gathering, in the blade flow channels. The outlet end of each blade is connected with
