Paper: Adjustable Valve Rod and Pull Tube Guide for Downhole Sucker Rod Pumps

The Adjustable Valve Rod and Pull Tube Guide is designed to allow for precise spacing in a down-hole sucker rod pump. In historical installations the spacing is based on the valve rod or pull tube length. This length is usually in one inch increments from the factory, or the rod or tube is field cut and threaded to maximize the pump compression ratio. This patented guide allows the spacing to be adjusted with greater precision and will compensate for manufacturing tolerances and reduce field cutting and threading of pull rods and pull tubes. This paper will describe how the guide is designed, its specific applications and its advantages over conventional sucker rod and pull tube guides.
