Abstract (en)
[origin: WO2010130923A1] The invention relates to a centrifugal pump. This pump (10) comprises a centrifugal impeller (20) and a casing (50) surrounding said centrifugal impeller, wherein the centrifugal impeller comprises a main passage (24) which splits into a first passage (241) and a second passage (242) that have a common supply inlet (22) running parallel to the axis of rotation (A) of the pump, said common supply inlet (22) being the inlet of the main passage (24). The first passage (241) has a radially extending first outlet (243) opening at a first diameter with respect to the axis of rotation (A) and able to supply fluid at a first pressure, while the second passage (242) has a radially extending second outlet (244) located behind the first outlet (243) and opening at a second diameter greater than the first diameter, the second outlet (244) being able to supply fluid at a second pressure that exceeds the first pressure.
