Introduction to LNG Submerged Pump
LNG (Liquefied Natural Gas) submerged pumps are crucial equipment in the LNG industry. These pumps are designed to operate while submerged in LNG, which is stored at extremely low temperatures (around -162°C). Their main function is to transfer LNG from storage tanks to various transportation or processing facilities, such as LNG carriers, regasification terminals, and industrial users. Submerged pumps offer several advantages, including high efficiency, reliable operation in cryogenic environments, and the ability to handle large flow rates. They play a vital role in ensuring the smooth and safe transfer of LNG throughout the supply chain.
