ABSTRACT:
The invention relates to an agitator tool for use with a progressive cavity pump for agitating a slurry of sand, heavy oil or water. The agitator tool has an elongate body having a lower end, an upper end, and a plurality of longitudinal grooves spaced between the lower and upper ends and radially about the body. The upper end is configured for coupling to a pump rotating element. Agitation members are pivotally mounted within the longitudinal grooves so as to be movable from an actuation position wherein the agitation members project outwardly from the body during rotation to agitate the slurry, to resting positions wherein the agitation members are folded within the grooves during installation or removal of the tool.
