Sucker-rod Pumping Units / API 11AX Downhole Pumps / Sucker Rod Pumping
Chinese API sucker rod pump
Comparing with conventional tubing pump, The API Tubing Pump has better performance in corrosion resistance & antifriction aspects. Plunger of it is nickel plated on alloy base, inside wall of barrel is plated hard cadmium, key parts, such as valve hood, valve ball, are made of materials with excellent mechanical performance and corrosion resistant property. Compared with conventional pump, the series of pump has a longer working life.
