PROBLEM TO BE SOLVED: To provide a movable blade pump capable of being easily assembled in a field, capable of dispensing with the leakage test of a sealing mechanism in the field, and capable of reducing the number of days for assembly after being transferred to the field. SOLUTION: The movable blade pump is provided with an impeller hub 50; a movable blade 90 rotatably attached to a bearing hole 59 provided on the impeller hub 50 and projecting a blade part 111 outward from the impeller hub 50; and a blade angle change mechanism 130 stored in an inside of the impeller hub 50, connected to the movable blade 90, and rotating the movable blade 90 to a prescribed blade angle. The movable blade 90 is provided with a blade eye 93 to which the blade part 111 is attached, and the blade eye 93 is detachably separated to an outer blade eye 93a and an inner blade eye 93b. The sealing mechanism 97 is disposed on the inner blade eye 93b side, and sealing by the sealing mechanism 97 can be maintained even when portions of the blade part 111 and the outer blade eye 93a are removed.
