Sucker Rod Pump
**Description**
A sucker rod pump, also known as an insert pump, is a type of downhole pumping equipment designed for oil extraction. It features two working barrels: the outer barrel and the inner barrel. The upper end of the outer barrel is equipped with a vertebral body seat and a clamp spring. The outer barrel is first inserted into the well along with tubing. Then, the inner barrel, which is fitted with a liner and piston at its lower end, is connected to the sucker rod and placed inside the outer barrel. Finally, it is secured using a circlip. This design allows for efficient fluid displacement and is commonly used in oil production systems.
