Abstract

In a two-way impeller in a centrifugal pump having a vertical drive shaft the impeller channels are formed such that a circulation flow is provided outwardly in the lower part thereof and inwardly in the upper part. By openings in the impeller between the two impeller inlets a suction effect is induced in a direction toward the upper inlet of the impeller. On the pump drive shaft and below the two-way impeller a centripetal-inducer may be mounted.
