Zusammenfassung:To provide a method of setting a performance characteristic of a pump for setting a performance characteristic of a pump, the pump including an impeller that takes in fluid from a suction port and that sends out the fluid toward a discharge port, and a diffuser provided in a flow passage between the impeller and the discharge port, where the diffuser includes a hub arranged in a central portion of the flow passage, a shroud arranged around a periphery of the hub, and a plurality of diffuser vanes radially arranged from an outer peripheral surface of the hub toward an inner peripheral surface of the shroud, and the method includes a mounting-position setting step of setting a mounting position of each of the diffuser vanes to be mounted on the hub according to the performance characteristic of the pump in a direction perpendicular to a radial direction extending from the hub toward the shroud.
