SS (Stainless Steel) Downhole Pump

SS (stainless steel) Downhole Pump
Sanjack Rod Pump Workshop was established in 1964 and is a first-class manufacturer and service provider in China. We have rich production experience and strong R&D capabilities. Related products include various series of tubing pumps, rod pumps and specialty rod pumps. In order to improve the corrosion condition of the downhole rod pump, Sanjack designed the SS (stainless steel) rod pump with precision rolling technology, after 2 years of research.
1). It perfectly solves the problem that the plug-in pump is corroded by corrosive substances such as H2S and CO2.
2). The precision rolling process is adopted to meet the precision requirements of the oil pump.

Oil well produced water contains a variety of corrosive substances, such as brine, Cl-1, SO4-2, HCO3-1, CO3-2, H2S, CO2, oxygen, etc., which may cause strong corrosion to carbon steel pumps.

Although stainless steel (S50100, S30400) is extremely resistant to corrosion, it is relatively soft and lacks hardness and strength. Traditional machining methods such as honing cannot meet the requirements of the dimensional accuracy of the pump barrel.


To this end, Sanjack adopts a precision rolling process to ensure the precision of the stainless steel pump barrel. The stainless steel pump barrel is chrome-plated to greatly improve the wear resistance.
