Abstract

A feed pump designed as side-channel pump has a shaft for a rotationally fixed connection to an impeller. Two flattenings are arranged on the shaft so that they are nonparallel to one another. The impeller is thereby mountable on the shaft only in an intended position so that the impeller is rotated in an intended direction of rotation in a casing. The feed pump may therefore be assembled in a particularly simple way.
