Deep Well 25 - 175 RWBM For Oil Production Produced By Zhongshi
Product Description
Rod pump is equipped with a support joint, support joint connected on the tubing string, and it is together with the tubing string down to the bottom. Plunger assembly is connected on the rod string and together with the whole pump down to support joint position, pump is fixed within the support joint by external force, plunger assembly is together with the sucker rod string up and down reciprocating movement to achieve pumping work.When inspection and maintenance pump,it need not to put out of the tubing string, only through rod string together put out of the whole pump, operation is simple.

Feature
1. Rod pump can be pulled out from the well directly.
2. Well inspection and work over is convenient.
3. Reduce the cost of pumping test.
4. Suitable for deeper well.
Operating principle of tubing pumps:
The pump barrel assembly directly fixed on a tubing string. the plunger assembly connected on the sucker rod string ,and with the up and down reciprocating motion, so as to realize the production process. Its advantage lies in: in the process of oil production, when the traveling valve and fixed valve side problem,valve side can be proposed by the sucker rod, piston and extractor , don’t put the whole pump and tubing string out of the well, reduce the work intensity and the operation cost
