Structures Of Non-Positive Displacement Pumps

Abstract
Improvements in the manufacture of self-priming pumps, characterized in that an impeller of radial blades, flexible in nature and fixed to the coupling shaft, is eccentrically housed inside the pump body, so that when the impeller rotates eccentrically, the blades they bend or extend according to the smaller or greater space between the impeller and the cylindrical wall of the pump body, creating closing and opening movements of the spaces included between the blades, giving rise to a continuous aspirating-impelling effect through the intake ducts and exit existing on the cover of the pump body.
