API11AX sucker rod pump factory

Subsurface sucker tubing pump is applied to pumping crude oil from oil well with pumping unit and sucker rod. Through sucker rod，tubing pump is descent to certain depth of oil. When pumping unit drives sucker rod to move up and down, sucker rod drives plunger of subsurface sucker rod pump move up and down in tubing barrel and pump crude to surface.

Pump barrel, plunger and accessories are specially treated which have the advantages of abrasive and corrosion resistance. It is suitable for pumping oil from oil well which contains sand, wax, gas and water.
