  • Pumping device for viscous slurry material
    Patent number: 6733247
    Abstract: A device for pumping a viscous slurry material. In one aspect, the pumping device is dimensioned to be insertable into the space between the side jambs of a standard building doorway. The pumping device is self-propelled and a mixer is removably attachable to the device for movement therewith. The pumping device includes a containment hopper and a swing tube pump having a swing tube with a wiper blade that agitates the viscous slurry material in the containment hopper. The pumping device has a frame assembled from multiple laser cut components. The pumping device is provided with a precision-machined manifold having a plurality of internal passageways directing a flow of hydraulic fluid to various pump components. A removable panel covers an aperture in a side wall of the containment hopper and is removable to provide access to the interior of the hopper for cleaning.
    Type: Grant
