ABSTRACT:
A material moving apparatus, and in particular, a material moving pump such as a manure pump. The pump includes a pumping chamber defined by interior chamber walls, and a piston or ram mounted for reciprocation in the chamber. The ram has side walls generally in conformance with the shape formed by the interior walls defining the chamber. The side walls of the ram are slotted or provided with grooves which induce turbulence in fluid flow between the side walls of the ram and the interior walls of the chamber to inhibit backflow of material from a position in front of the ram to a position behind the ram. The pump thus operates efficiently to pump material of low viscosity or material of low density.
