The plunger of the rod sucker pump is connected with the sucker rod and moves up and down. The pump barrel is fixed at the top or bottom by a fixing device.
Features of Rod Suction Pump
1. The pump barrel of this pump only bears external pressure and does not bear the stretch caused by the weight of the oil column. Therefore, the pump gap changes very little, and it is most suitable for use in deep wells.
2. Compared with other standard deep well pumps, the pump barrel is not easy to be broken or deformed under pressure.
3. Since the pump body can swing around the bottom fixing device, it can be used in inclined wells.
4. This kind of pump is not suitable for long-stroke pumps, nor is it suitable for sand-containing wells, because sand is easy to accumulate in the annular space between the pump and the tubing and cause the pump to jam.
