ABSTRACT:
A centrifugal pump (10) conveys a fluid from a rotor wheel inlet opening (8) via a rotor wheel outlet opening (9) into a pressure nozzle (4). The fluid has a velocity profile between the outer flow line (c) and the inner flow line (d). The method allows a fluid to be conveyed with a centrifugal pump (10) in such a manner that the velocity profile is continuously changed in dependence on the delivery flow (Q) which means that an abrupt change of the velocity profile when transferring from one load condition, e.g. at maximum efficiency, to another load condition, e.g. a partially loaded region, is avoided which results in a stable H/Q)-characteristic.
