A centrifugal pump device includes a motor unit and a pump unit. The motor unit includes two elongated stator units, and a rotor disposed rotatably on a motor housing unit between the stator units. Each of the stator units extends in a direction perpendicular to and spaced apart from a rotating axis of the rotor. The pump unit includes a pump chamber, a plurality of impeller blades disposed in the pump chamber and anchored to the rotor, a pump housing unit attached fixedly and sealingly to the motor housing unit, a liquid passage in fluid communication with the pump chamber, an inlet passage in fluid communication with the liquid passage, and an outlet passage in fluid communication with the pump chamber and extending at least partially into a between-stator region.
