Specifications

subsurface sucker rod heavy wall tubing pump

chrome plated barrel

nickle sprayed plunger

tungsten carbide valve and ball

The workover process of tubing pump is: firstly the barrel being connected to the tubing is directly run into the well at desired depth and then the plunger is run into the barrel with the sucker rod. The applicable tubing pump is larger in size than rod pump in the same tubing. Tubing pump has simple structure so the displacement is bigger and it is suitable for the shallower well with shallow depth and high production. Comparing with conventional tubing pump, ours has better performance in corrosion resistance antifriction aspect.  Plunger of it is nickel plated on alloy base, inside wall of barrel is plated with hard cadmium, key parts, such as valve hood, valve ball, are made of materials with excellent mechanical performance and corrosion resistant property.
