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.
