API 11AX Rod Pump and ultra long stroke rod pump
1.API 11AX Rod pump
According to design,rod pump can be assembled and connected to the lower end of the sucker rod ont the ground,run into the well as a unit,and fixed in the tubing by seating nipple pre-fitted in the tubing.When the anti-impact distance is adjusted and the pumping pressure is tested,the pump will start to work.

2.Ultra long stoke Rod pumps consists of casing assembly,pump tube assembly,ultra long plunger asssembly and its accessories.The stroke can reach 30m.The efficiency of oil production can be improved by cooperating with intelligent pumping unit.Pull out the pump tube assembly out of the oil pump through the sucker rod when checking the pump unit wothout lifting the tubing,which proves to be a rather convenient process.
Main features:Shorten the working time,reduce the frequency of tubing unloading,prolong the service life of tubing,save the operating cost.
The oil jacket can be connected with the upper rod string,so measures such as positive well washing,down well testing and steam injection thermal recovery can be carried out without lifting the string,which is convenient and reliable.
Without oil discharger,the self-discharging function can be realized after lifting the rod,which has the advantages of low cost and reliable safety.

Technical Properties of main components of Oil-well pump
1.Inner hole carboniitriding process is applied to the pump barrel.The surface haardness of the pump tube treated by nitrocarburizing can achieve 58~66HRC,the nitrocarburized layer is 0.95~1.2mm from internal surface.
2.Nickel -base alloy is aprayed on the surface of the plunger,The hardness of the base is 55~62HRA,and the surface hardness is >=55HRC
