ABSTRACT:
A regenerative pump apparatus has a housing and a substantially disc-shaped impeller rotatably housed by the housing. Circumferential rows of radial vane grooves are formed in the outer peripheral portions of both side surfaces of the impeller. Each circumferential row includes first vane grooves of an axial depth equal to or greater than a half of the impeller thickness and second vane grooves of an axial depth smaller than a half of the impeller thickness. The first and second vane grooves are arranged alternatingly in the circumferential direction in each row, such that the first vane grooves and the second vane grooves in one row are axially aligned with the second vane grooves and the first vane grooves in the other row.
