2018023 A COMPARISON OF API ROD PUMPS, MODIFIED API PUMPS, AND SPECIALTY PUMPS

This paper will discuss the two API pump designations the rod pump and the tubing pump. The rod pump is occasionally referred to as an insert pump and has three variations; stationary barrel top anchor, stationary barrel bottom anchor, and traveling barrel bottom anchor. Available modifications that are not covered under API but are commonly used to improve run time or efficiency will be discussed. Several special design pumps will be described along with their advantages. A reader will be able to recognize the standard API pump designs, API designs with modifications, and specialty pumps.  In the end, the reader will be able to evaluate which application of each pump design should be used.
