Brass Sucker Rod Pump

Brass Sucker Rod Pump
For the corrosion of downhole sucker rod pumps, after 2 years of research, Sanjack developed brass and stainless steel sucker rod pumps using precision rolling technology. At present, Sanjack is the first brass oil pump manufacturer in China, and its products have been successfully exported to the United States, Canada, Russia, Tunisia, Kazakhstan, Iran and other countries.

1). Precision rolling process is applied to meet the requirement of oil pump precision.
2). Perfectly solve the problem that the insert pump is corroded by H2S, CO2 and other corrosive substances

Brass includes a range of copper-zinc alloys, including properties such as ductility, strength, hardness, color, machinability, wear resistance, antimicrobial resistance, corrosion resistance, and electrical and thermal conductivity. UNS C44300 Brass Alloy is a type of brass, also known as Naval Brass and Arsenic Brass.

Due to its good corrosion resistance, C44300 is mainly used as piping for steam condensers cooled by fresh water, salt water or brackish water. One of the uses of naval metal pipes is in heat exchangers in oil refineries where corrosion is severe, but also in feedwater heaters and heat exchanger equipment and other industrial processes.

Navy blue brass is very corrosion-resistant, but its hardness and strength are very low, so traditional machining methods, such as honing, cannot meet the dimensional accuracy requirements of the pump barrel.
In order to solve this problem, we adopt precision rolling process to ensure the precision of brass pump barrel. The brass pump barrel is chrome plated to improve the wear resistance.
