Sucker Rod Pump
**Description**
A Sucker Rod Pump, also known as an insert pump, is a type of downhole pumping equipment used in oil and gas production. It features two working barrels: the outer barrel is installed into the well first, equipped with a vertebral body seat and clamp spring at its upper end. The inner working barrel, which includes a liner and piston at the lower end of the sucker rod, is then connected and inserted into the outer barrel, and fixed in place using a circlip. This design allows for efficient fluid displacement and is widely used in various oilfield applications.
