Abstract

Described herein is a centrifugal pump (100), particularly for a coolant in a motor vehicle, comprising a first centrifugal pump stage (102) having a first pump housing (108), a first impeller (110) mounted in the first pump housing (108) in a rotating manner, a drive device (106) for coaxially driving the first impeller (110). In an embodiment, a second centrifugal pump stage (104) has a second pump housing (114) and a second impeller (116) is rotatably mounted in the second pump housing (114). Further, 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 (110) to an inlet region of the second impeller (116).
