Abstract
The present invention relates to a centrifugal pump. Especially, the invention concerns a centrifugal pump capable of pumping liquid as free of pressure fluctuations as possible. Centrifugal pumps of this type are used, for instance, as feed pumps for paper machine head boxes. A characteristic feature of the pump of the invention is that the vanes (22, 24) of the impeller and the volute cut-water (18) at the junction of the spiral casing and the pressure opening serving as the element generating pulses with the vanes are positioned at a distance s from each other so that the distance mentioned is at least 7 % of the diameter of the impeller (14).
