Abstract

This invention relates to a centrifugal pump and to a method of operating such a pump. In order to obtain improved de-areation of the pump it is characterized through the combination of at least one rib (7), which extends substantially parallel to the pump wheel shaft (8) and is provided on the shaft-facing inside of a pump housing cover, a seal housing or the like (1), with a pump wheel (4) which has at least one through aperture (6) which is located nearer the pump wheel shaft than said rib. The pump defined above is operated in such a manner that an over-pressure is maintained on the rear pump wheel side which faces the seal housing.
