Because of the 55 close fit between the sides and the sealing ring the entrained air in the fluid, which is usually water, cannot escape but is discharged from the pump with the fluid or water.

I desire to comprehend within my invention such modifications as may be embraced within my claim and the scope of my invention. For instance, a by-pass 26 for diverting a portion of the iiow may be provided.

Having thus fully described my invention, what is claimed as new and desired to be secured by Letters Patent, is:

In a pump, a casing comprising a pair of sides with contiguous axial flanges forming a peripheral channel and a sealing ring in said channel cooperating therewith to form an air seal, each of said sides having a pair of inwardly directed ridges thereon, a shaft mounted in said casing,

a rotor on said shaft having a rib on its peripheral surface in sealing engagement with two of said inwardly directed ridges and its side faces in sealing engagement with the other` inwardly directed ridges to form a plurality of pumping channels, said rotor having a plurality of buckets o'n the periphery thereof at each side of said rib, said sealing ring having ports'forming a common inlet and a common outlet for said pumping channels, said sealing ring surrounding said casing and having a rib extending across said ports, the rib on said sealing ring cooperating with the two of said inwardly directed ridges having sealing engagement with the rib on said rotor to direct the fluid into the pumping channels and to seal said pumping channels apart from one another.
