Long Plunger Anti-sand Sucker Rod Pump

1. The inner wall of the long plunger sand control pump is chrome-plated (thickness 0.1-0.15mm), resistant to H₂S and CO₂ corrosion, and suitable for harsh environments with mineralization ≥10,000mg/L. 2. The long plunger sand control pump uses API standard threaded connections (such as 2 7/8 TBG), and plunger replacement can be completed without special tools. 3. The key components of the long plunger sand control pump are replaceable, such as the pump barrel, plunger, and valve group, which can be replaced independently to avoid overall scrapping and reduce maintenance costs by 40%.
