Anti-corrosion oil well pump is adopted to enhance the corrosion resistance and impact resistance of oil well pump and valve cover, especially suitable for oil wells with high salinity, high corrosion and valve cover easily broken.

For conventional oil well pumps, sand particles easily enter the sealing gap during the oil pumping process, causing wear of the pump barrel and plunger. Due to the sand scraping ring, the diameter of the sand particles in the well fluid passing through the sand filter screen is smaller than the size of the sealing gap, which will not cause wear on the pump barrel and plunger, and will not cause sand stuck; it is different from the sealing ring of the soft seal pump: the upper and lower ends of the The pressure is balanced, the positive pressure of the pump barrel is just its own elastic force. Hence less wear and longer service life.
