ABSTRACT:
A clean-in-place pump is disclosed in which the hub of the impeller extends into a pocket in which particles from the fluid being pumped may become entrapped. Axial slots in the drive shaft of the impeller create turbulence within the pocket to dislodge the particles. Back vanes on the impeller and passages through the impeller vane mounting disc cooperate to cause fluid to circulate through the pocket to flush out the particles.
