Abstract: An apparatus for pumping mortar. A hopper for containment of mortar is mounted on a portable frame. A mortar pump has an inlet located within a lower portion of the hopper, and a discharge located outside the hopper. A rotary drive shaft has a lower end attached to the mortar pump, and a median portion passing through the contained mortar. The drive shaft is oriented at a vertical angle sufficient so that an upper end of the shaft extends above an upper level of the mortar. An engine, also mounted on the frame, rotates the upper end of the drive shaft, powering the mortar pump. One end of a mortar distribution hose is connected to the discharge of the pump. The other end of the hose extends to a remote location, and is fitted with a mortar application nozzle. Mortar is pre-mixed in a concrete mixer and poured into the hopper. The mortar pump forces mortar through the distribution hose and out the nozzle, where it is directed by a mason on to joints and into grout lines.
