Abstract (en)

An intake device is proposed for a vertical pump having a suction bell (21), an outlet (22) and a column pipe (24) arranged between the suction bell (21) and the outlet (22), the intake device comprising an inlet section (2) with an inlet opening (5) for a fluid to be pumped by the vertical pump, an outlet section (4) for guiding the fluid into the suction bell (21) of the vertical pump, and a cylindrical section (3) extending in an axial direction (A) and connecting the inlet section (2) with the outlet section (4), wherein the intake device is configured to receive and to surround the suction bell (21) and at least a part of the column pipe (24) of the vertical pump (20), and wherein the outlet section (4) comprises a bottom wall (41) for closing the intake device at a lower end, wherein the inlet section (2) is designed as a funnel-shaped inlet section (2) and tapering in the axial direction (A) from the inlet opening (5) towards the cylindrical section (3), wherein the inlet section (5) is configured to surround the column pipe (24) of the vertical pump with the inlet opening (5) extending completely around the column pipe (24). In addition, an arrangement comprising a vertical pump (20) and an intake device (1) is proposed, as well as a method of retrofitting a vertical pump.
