The pump comprises, within a cylindrical annular pump body closed by a lateral plate: a rotor with centrifugal blading, an axial intake sleeve connected to this rotor and an axial delivery (outlet flow) outlet through the plate. The pump includes, within the pump body, an annular collecting chamber 18 formed facing the radial outlet of the rotor 1 and an annular partition 24 interposed between the annular collecting chamber 18 and the intake sleeve 20 of the rotor 1 and which is equipped, at its periphery, with an annular passage 25 equipped with fixed blading 28, the overall line of which is inclined with respect to the circumferential line of the annular passage 25. Application to low-power centrifugal pumps converting the radial outlet of the pump rotor into an axial delivery with a low noise level. <IMAGE> |
