Deep Well Oil Well Pump


When running the pumps in deep wells, there may exist the following problems:

  • The valve cage may break and fail;
  • The valve may be damaged and invalid;
  • When the pump barrel is stretched and deformed, the pump plunger will not work smoothly, and even the barrel may stuck or break;
  • The oil well pump efficiency may be reduced to less than 30%.

Sanjack developed a lot of special oil well pumps to solve the above problems, including a suspension pump, bridge-type pump, solid plunger pump, etc.

Anti-bending & Anti-abrasion

Because of special bridge-type structure, the pump barrel is suspended in the outer barrel. No bending and no abrasion.

Low leakage

The suspension structure makes the pump barrel internal and external pressure the same, effectively reduces the leakage.

Long service life

The specially designed structure makes the pump barrel does not bear the alternating force load during up and down strokes to greatly extend life of the product.
