Abstract
A centrifugal pump for pressurizing fluid by using centrifugal force has an impeller and a casing. The impeller is operated rotatably by an actuator. The casing houses the impeller. The impeller has blades arranged one after another in a circumferential direction of the impeller, and a passage is defined between the blades adjacent to each other in the circumferential direction. The passage has a linear portion and a curved portion. The linear portion extends linearly and has a uniform cross section. The curved portion is connected to an end of the linear portion, extends as being curved to a radial-outer side of the impeller, and decreases in cross section toward the radial-outer side.
