Oilfield Production Well Pump Tubing / Subsurface Sucker Rod Pump With OEM Service
Oilfield Production Well Pump Tubing / Subsurface Sucker Rod Pump With OEM Service
Product description
Tubing pumps are classified as high volume, heavy duty pumps. Maximum production can be expected with this type in relation to the size of tubing. However, because of the large plunger diameter, the fluid load will be greater than with an insert pump. Therefore, depending on the rod string and size of the surface pumping equipment, the depth at which a tubing pump can run is limited. The pump barrel serves as a section of the tubing. The plunger and traveling valve are run in the well with the sucker rods. The standing valve can be one of two types; fixed or retrievable.
Features
The pump barrel is machined by using the high quality special purpose blank; the internal surface has the chrome-plating or the nickel phosphorus compound plating to achieve the good intensity, the rigidity, wear-resistance and anti-corrosion.
