C化工泵hemical pumps generally use corrosion-resistant materials, such as glass fibers, pvc, fluoroplastics, stainless steel, suitable for extracting corrosive liquids in bottles, barrels, cylinders, tanks or other containers. It is widely used in chemical industry, petroleum, metallurgy, light industry, synthetic fiber, environmental protection, food, medicine and other sectors. Chemical pump has the advantages of stable and reliable performance, good sealing performance, beautiful appearance, convenient use and maintenance, etc. Before the chemical pump works, the pump body and the feed pipe must be filled with liquid to form a vacuum state. When the impeller rotates rapidly, the blade impels the liquid to rotate at a high speed. Under the action of centripetal force, the liquid flies away from the impeller. After the water in the pump is thrown out, the central part of the impeller forms a vacuum area. Under the action of atmospheric pressure, the liquid material is pressed into the feed pipe through the pipe network. In this way, continuous delivery can be completed.
