Abstract
An impeller for a feed pump designed, in particular, as a side channel pump or as a peripheral pump has two disk parts connected fixedly in terms of rotation to one another. The disk parts can be manufactured in simply constructed molds, for example by the injection molding method, and can be provided with virtually any desired geometries of guide vanes. The impeller has high stability due to the rotationally fixed connection between the disk parts.
