Abstract

The invention relates to an intake device (2) for a vertical pump. This intake device (2) comprises a fluid inlet (6) and a fluid outlet (8). The fluid outlet (8) is aligned perpendicular to the fluid inlet (6). The intake device (2) further comprises a flow channel (10) which connects the fluid inlet (6) with the fluid outlet (8). The flow channel (10) has a first section (12) which directly follows the fluid inlet (6) and a second section (14) which follows to the first section (12) and which leads to the fluid outlet (8). In the second section the direction of the flow channel (10) changes in an angle of at least 90°. In the area of its first section (12) the cross section of the flow channel (10) changes from a circular cross section at the fluid inlet (6) to an elliptical cross section and in the area of its second section (14) the cross section of the flow channel (10) changes from an elliptical cross section to a circular cross section at the fluid outlet (8), wherein the diameter (C) of the fluid outlet (8) is smaller than the diameter (D) of the fluid inlet (6).
