Brass Sucker Rod Pump

To solve downhole sucker rod pump corrosion, Sanjack developed brass & SS sucker rod pump using precise rolling after 2 year’s studying. Now, Sanjack is the first manufacturer in China and the products have been successfully exported to America, Canada, Russia, Tunisia, Kazakhstan, Iran, etc.

  • Perfectly solves the problem that the insert pump is corroded by H2S, CO2 and other corrosive substances.
  • Precision rolling process is adopted to meet the requirements of oil pump precision.

Brass refers to a broad range of copper-zinc alloys comprising a variety of properties such as ductility, strength, hardness, color, machinability, wear-resistance, antimicrobial, corrosion-resistance, and electrical and thermal conductivity.

UNS C44300 brass alloys are one of the types of brass, which also are known as admiralty and arsenical brass.

As to C44300,due to its good corrosion resistance, which is mainly acts as tubing of steam condensers cooled with fresh, salt or brackish water.

One of the USES of the Admiralty Metal Tubes is that it can be used as heat exchangers in oil refineries with serious corrosion, in the meantime, it also can be used for feed-water heaters and heat-exchanger equipment as well as other industrial processes.

Although navy brass is extremely resistant to corrosion, it is relatively soft and has very low hardness and strength.

Conventional processing methods, such as honing, cannot meet the requirements of the dimensional accuracy 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.
