1.Description
 
     Rod pump is also referred to as " insert pump" as its plunger is attached to and moves up and down with the sucker rod string. It reduces the time of work over deep well as it is not necessary to pull all the tubing out of the well hole when checking the pump, which makes the operation quicker and the service life of tubing longer. The rod pump is in a state of " free hanging", so it is suitable for deviated wells.
    It composes of the following parts: tubing collar, extension coupling, barrel coupling, pump barrel, travelling valve bonnet, plunger, puller, and fixed valve.
 
2.Charateristics:
 
1) The inner surface of the pump barrel is processed with carbonization quench and chrome plating technology
2) The plunger surface is processed with thermal metal spraying technology
3) The pump meets the requirement of long stroke, high speed and deep producing
4) It has the advantages of high pumping efficiency, large displacement, wear and corrosion resistance, long operation and easy repairing.
5) It accords with API SPEC 11AX standard, and has the certificate of authority to use the official API monogram.
