摘要
Device for pumping gas-containing suspensions with a fluidizing rotor (5) with one or more blades (6) and a pump impeller (3) and a pressure port, the fluidizing rotor (5) protruding into the suction port (18) of the pump and a hub (17 ), characterized in that the ratio of the suction nozzle diameter (Ds) to the free length (FL) of the fluidization rotor (5) satisfies the following equation: Ds / FL> 0.0024 1 / mm * Dp0.7worinDsden the suction nozzle diameter in millimeters FL is the free length of the Fluidization rotor (total length - length of the hub) in millimeters Dp designates the pressure port diameter in millimeters.
