The term IT CAN BE PUMPED can be solved by the four letter word IRON. IRON is a chemical element that is found in nature and is used in many industries. It is a strong, malleable metal that is often used to make tools, weapons, and other objects. IRON is also used in the production of steel, which is a combination of IRON and other elements. IRON can also be pumped, meaning it can be moved from one place to another using pumps.
