Abstract

See full text

A method for producing a centrifugal pump impeller having a base plate, which is a single piece with pump blades and a cover plate, which consists of a thermoplastic material, wherein contact areas are available, which are heated and melted by means of ultrasonic excitation and form a close bonded connection after cool-down. The objective of the invention is to ensure inherent stability with the individual parts and a simple and reliable pre-assembly as well as a fixed mechanical connection, wherein only a small amount of excitation energy is required, with a centrifugal pump impeller comprising a base plate and cover plate.
