Introduction of API rod pump:
API rod pump is a heavy oil mining equipment. API rod pump is divided into two parts: one is the sealing support joint connected to the oil pipe, and the other is the rod pump. API sucker rod pump, as a whole, can be fixed and sealed at a predetermined position in the oil pipe with the sucker rod, so it is also called "Insert rod pump". The oil well pumps produced by our company adopt API design standards. There are three types of API sucker rod pumps, with specifications ranging from φ28-φ57, covering all specifications of API sucker rod pump series. In the process of lifting and lowering the oil pump, API sucker rod pump does not need to lift and lower the oil pipe. It is easy to operate, saves time and effort, and occupies a short well time. API sucker rod pump can save more than half of the operation time, thereby reducing operation costs. At present, our company's API sucker rod pump is widely used in domestic oil fields.

Advantages of API rod pump:
1. During the operation of lifting and lowering the oil pump, the insert rod pump can be lowered into the oil pipe with the sucker rod as a whole, without lifting and lowering the oil pipe. Therefore, our insert rod pump is easy to operate, saves time and effort, and occupies a short well time.
2. When replacing insert rod pumps of different pump diameters, by improving the structure, the oil pipe column can be kept unchanged; that is, the sealing support joint of the insert rod pump is a universal part.
3. The insert rod pump body can swing around the fixing device. The rod-type oil pump is suitable for inclined wells and deep wells. The insert rod pump solves the problems of severe sand production and large changes in downhole pressure in heavy oil wells.

Application of API rod pump:
The performance and technical requirements of our company's Insert rod pump meet the requirements of API standards and GB/T18607-2008 standards. This series of Insert rod pumps are suitable for thin oil wells, heavy oil wells, high-condensate oil wells, steam drive wells, deep wells, sand-containing wells, gas-containing wells, etc. API sucker rod pump solves the problem of severe sand production and large changes in downhole pressure in heavy oil wells. The insert rod pump can be lowered into the tubing as a whole with the sucker rod. The tubing can be inspected without lifting the API sucker rod pump, and the pump barrel is subjected to less force. The insert rod pump is especially suitable for deep pumping, and is also suitable for inclined wells and wells with sand and high viscosity.

FAQ of API subsurface rod pump:
1. What is an API subsurface rod pump? What are the main structures of an API subsurface rod pump?
The API subsurface rod pump (also called Insert rod pump) is mainly composed of a seal support joint and a rod pump. The API subsurface rod pump can be lowered into the tubing with the sucker rod as a whole, which is easy to operate.
2. Does the API subsurface rod pump perform well in deep or inclined wells?
Yes. The Insert rod pump has the characteristic of swinging around a fixture, which is very suitable for inclined and deep well environments.
3. Can your API subsurface rod pump be customized?
Yes, our API subsurface rod pump can be customized according to your needs.
