Carbon Steel Sucker Rod Pumps 11B API Oilfield Equipment
Sucker Rod Pumps
Sucker Rod pump is also known as insert rod pump, it is one type of the conventional sucker rod pumps. The rod pump is connected to the sucker rod directly, it can be pulled out with sucker rod and does not influence the tubing, so the well inspection and workover is more convenient. It can save half times and reduce cost of the pumping test, thus the rod pump is suitable for the deeper well.
Shengji began to manufacture rod pump in the 1960s and we are the main insert and rod pump supplier in China. Our rod pump is strictly conforming to API SPEC 11AX (or GB18607) standard.
Depending on the wall thickness of the barrel, the rod pump can be classified as either a thin wall rod pump or a thick wall rod pump. At Shengji, we manufacture these insert rod pumps according to different requirements of customer’s.
