Product Information

Tubular pumps are named because the pump barrel assembly (including the pump barrel, extension joints, etc.) is directly connected to the tubing by thread and becomes part of the tubing. The characteristics are as follows: 1. In the case of the same tubing size, applicable tubing Pump diameter is larger than that of rod pump, so it is suitable for large displacement wells. For oil wells with a larger liquid discharge capacity, a pipe type pump with a pump diameter larger than the inner diameter of the oil pipe can also be installed by means of a disconnector. 2. Solid structure, large flow channel area, can extract viscous crude oil. 3. Due to the limitations of the strength of the sucker rod string and the elastic extension, the tubular pump is usually used in shallow and medium-deep wells with large displacements. technical parameter: 1.
