Zusammenfassung:	A centrifugal pump is provided, which includes a rotor assembly, the rotor assembly includes an impeller including multiple blades and a blade fixing portion, the blades and the blade fixing portion are integrally formed by injection molding, and the blades are circumferentially distributed at equal intervals along the blade fixing portion. The blade includes a first side, a second side, a blade top portion and a blade root portion, and the blade root portion and the blade fixing portion are fixed by injection molding. The blade top portion is a cantilever end of the blade, and the first side and the second side are arranged between the blade root portion and the blade top portion. The rotor assembly arranged in such manner can improve the hydraulic efficiency and lift of the centrifugal pump.
