Abstract (en)
[origin: WO2011026678A1] The invention relates to a centrifugal pump (100), in particular for a coolant in a motor vehicle, comprising a first centrifugal pump stage (102) having a first pump housing (108), and a first impeller (110) rotatably mounted therein, and to a drive device (106) for coaxially driving the first impeller. A second centrifugal pump stage (104) has a second pump housing (114) and a second impeller (116) rotatably mounted therein and an intermediate housing (120) is located between the first and the second pump housing (108, 114) for diverting a fluid flow dispersed by the first impeller to an inlet region of the second impeller.
