Super Duplex Stainless Steel pumps

Duplex stainless steels are based around a composition of 22% chromium, whereas super duplex stainless steels are based around a composition of 25% chromium. By increasing the chromium content, the level of pitting corrosion resistance is also increased

Super Duplex Stainless Steel pumps are often used in applications such as long term immersion in seawater, or industrial processes in aggressive solutions. One of the biggest applications therefore is a seawater lift pumps on offshore platforms and pumping produced water
