LEWA Herbert Ott GmbH + Co Kg have reportedly installed the world's "two biggest high-pressure process diaphragm pumps" at a natural gas facility in Hammerfest, Norway. The pumps, weighing around 63 tons each, are used for the re-injection of CO2 into the natural gas field. Each pump delivers 29,000 GPH liquid CO2 against a pressure of 3,120 psig. They also liquefy and pump the CO2 back into the sub-sea field. For more information visit www.lewa.com.
