Product Description
It is applied to the oil well containing corrosive medium such as salt sulfur, carbon dioxide and bacteria and the wells with fewer sands.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. Subsurface pump Per API Spec.11AX.This pump barrel uses a suspension structure, thus it improves the load bearing structure and makes the pump work in the deep well. The setting depth of pump could be 500-1500 meters deep. This pump has the following characteristics: to prevent bending, the pump uses the gap bridge structure, the barrel is suspended in the outer section and does not bear any pressure thus, not easy to bend. The space between the plunger and barrel reduces eccentric wear thus, extended the service life and guarantee improved pump efficiency. To prevent loss, the related eccentric distance ε=0. This eccentric distance between barrel and plunger reduce pump loss. This pump is suitable for the deep wells, which where one needs to hang more tail pipes.
