Abstract
In a feed pump designed as a side-channel pump, an impeller is held so as to be slightly pivotable with respect to a shaft about an axis running transversely to the shaft. The impeller is thereby adaptable to tolerances of a casing. Rubbing of the impeller on the casing is also prevented as a result. The feed pump consequently generates a particularly low level of noise.
