Abstract
A centrifugal pump having a single-blade rotor whose central suction mouth, remote from the driving shaft, is in alignment with the inlet opening, the inlet opening forming an annular collar which so projects into the inside of the rotor that the inner end of the rotor blade forms a narrow gap with the outer surface of the collar.
