Abstract
A centrifugal pump includes a pump housing having a suspension inlet and a suspension outlet and a flow channel between the inlet and the outlet, a shaft mounted by bearings for rotation about a center axis, an impeller which is rotatable by the shaft, in alignment with the inlet and arranged to be rotated about the axis in the flow channel, and gas collecting openings for gas removal arranged in the flow channel. The inlet end of the flow channel includes a number of static vanes comprising gas collecting openings, the vanes extend radially from an inner wall of the flow channel toward the center of the flow channel and are upstream of the impeller.
