RHAM Subsurface Sucker Rod Pump
Sucker Rod Pump
**Description**
A sucker rod pump, also known as an insert pump, is a specialized oil well pumping system designed for efficient fluid extraction. It features two working barrels: the outer barrel is installed into the well first, equipped with a vertebral body seat and clamp spring. The inner barrel, which contains a liner and piston at its lower end, is then connected to the sucker rod and inserted into the outer barrel, secured by a circlip. This design allows for smooth operation and reliable performance in various downhole conditions.
