Metering and dosing pumps are positive displacement pumps designed to accurately and precisely deliver specific amounts of liquid or chemicals into a process stream. These pumps are critical in applications where precise chemical dosing is necessary, such as in water treatment, food processing, pharmaceuticals, and chemical manufacturing. Metering pumps are commonly used for injecting precise amounts of liquids like additives, disinfectants, or reagents into a system in controlled volumes and at consistent flow rates.
