Abstract
An inducer and a submersible pump for pumping a slurry comprising solids and viscous fluids, the inducer mountable to the pump's drive shaft adjacent to and immediately upstream of an impeller mounted on said shaft. The inducer comprises a hub, two to four inducer blades extending outwardly from and wrapping helically around the hub, the hub and the inducer blades defining a plurality of channels A trailing edge of each inducer blade is positioned snugly adjacent to and in fluidical alignment with a leading edge of a corresponding impeller blade when the inducer is mounted on the drive shaft of the pump, such that a velocity curve of the slurry is smooth as the slurry travels from a leading edge of the inducer blades to the leading edge of the impeller blades.
