    Abstract: The invention relates to a centrifugal pump comprising a pump housing made of injection-molded plastics with a first housing part, which is designed as a single piece with a suction connection and a pressure connection, and comprises a sealing area, by means of which said first housing part is joined in a liquid-tight manner to a second housing part, that receives an electric motor, and a motor housing part. It is the object of the present invention to provide a centrifugal pump, in which very good leak tightness is achieved with minimum number of parts, minimum weight and minimum assembly costs with universal applicability without impairing the visual overall impression of the centrifugal pump. This objective is achieved according to the invention in that the second housing part is made of a material that is permeable to laser light of a wavelength or a wavelength range, and the first housing part is made of a material that absorbs the same laser light, and the first housing part and the second housing part are heat-sealed to one another.
