Paper: Classification and Application of Sucker Rod Pumps

The API undertook a tremendous job of classifying and identifying the many subsurface pumps available to the industry. As a result of their efforts we now have asset of symbols for the purpose of pump identification. All pumps not covered by this set of symbols are classed as Types of pumps. They, too, are made up of as many API parts as possible to keep down the expense of handling so many different parts by both manufacturer and operator.
