HELICAL ROD GUIDE A rod guide for use with a rotating progressing cavity pump rod string which minimizes the resistance offered thereby to the axial flow of well fluids. This rod guide decreases turbulence and thereby reduces internal abrasion of the rod and tubing wear together with energy demand. The helical guide may employ either one or two lead vanes.
