More Information
Summary:In a first aspect the invention relates to an intake device (3) for creating a uniform flow of liquid entering a pump (4), which flow of liquid is free from rotation and swirls about the inlet of said pump. The inlet device (3) comprises an inlet section (11) having an orifice (14) and a decreasing cross section area seen in the direction from said orifice (14) for gradually accelerating a flow of pumped liquid, a redirection section (12) for redirecting the flow of pumped liquid from a mainly horizontal direction to a mainly vertical direction, and an outlet section (13) arranged to be connected to an inlet (6) of a pump (4). The device is characterized in that at least a part of a circumferential wall edge of said inlet section (11) extending around said orifice (14) comprises a bevel (17). In a second aspect the invention also relates to a pump station comprising such an intake device.
