ABSTRACT:
A well pump sucker rod guide which is a tubular integral body element formed of an elastic minimum friction type material and provided with a longitudinal bore formed along the longitudinal axis of the body, a transverse mounting slot opening from a side of the body into the bore dividing the body into opposite end portions, and a longitudinal mounting slot in each end portion extending radially inwardly into the bore and opening at one end through an end of the body and at the other end into the transverse slot, one of the longitudinal slots extending in the opposite radial directions from the other longitudinal slot, and each said slot being defined by radially outwardly diverging guide walls which also diverge toward the transverse mounting slot. The guide is mounted on sucker rod sections to centralize the reciprocating rod in a production tubing in which a pump is mounted and operated by the rod.
