ABSTRACT OF THE DISCLOSURE A slurry pump is provided having an impeller housing with an impeller chamber receiving an impeller having a rotation axis and a plurality of wedge-shaped pockets on a fluid engaging face. A fluid housing is adjacent to and cooperates with the impeller housing to form a fluid chamber adjacent the impeller. An input passage to the fluid housing is perpendicular to and offset from the rotation axis and links an exterior of the slurry pump to the fluid chamber to permit fluid to enter the pump. An output passage from the fluid housing links the fluid chamber to an exterior of the pump to permit fluid to exit the pump. A feedback input passage links the output passage back to the fluid chamber to permit a portion of the fluid exiting the pump to reenter the fluid chamber, thus creating a dynamic and continual prime.
