ABSTRACT:
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. The fluid housing includes a circular wall member with an input passage eccentrically located relative to the circular wall member and the rotation axis of the impeller. The fluid housing further includes a side wall member including the output passage, with the side wall member surrounding the circular wall member and cooperating with the circular wall member to define the fluid chamber. The side wall member has an interior width substantially equal to the inside diameters of the input and output passage. The capacity of the pump can be changed by interchanging different fluid housings.
