The present invention relates to a pneumatic centrifugal pump extendable in length, and, more particularly, to a pneumatic centrifugal pump extendable in length including a plurality of frames which is formed in a cylindrical tube shape and has first joining portions formed at ends of both sides; an impeller part having second joining portions each of which is located between the frames and corresponds and is connected with the first joining portion, a main impeller consisting of a body formed on the inner circumferential surface of each of the second joining portions, having a conical-shaped body, and located inside each of the frames and of a plurality of blades integrally formed along the outer circumferential surface of the body, and an auxiliary impeller which is formed on the outer circumferential surface of each of the second joining portions and located outside each of the frames; and an auxiliary case part which has a first auxiliary case having an oscillation part in which compressed air is oscillated and a second auxiliary case having a discharge part from which the compressed air oscillated through the oscillation part is discharged and which is joined to the outside of the frame to surround the circumference of the auxiliary impeller by being connected with each other. The pneumatic centrifugal pump extendable in length according to the present invention can be easily extended in length through the connection of the frames, the impeller part, and the auxiliary case part. |
