Introduction to Metering Pumps
A metering pump, also known as a dosing pump, is a type of positive – displacement pump used to precisely control the flow rate of a fluid. It is designed to deliver a specific volume of liquid at a constant rate, regardless of pressure changes within the system. Metering pumps are widely used in various industries such as water treatment, chemical processing, food and beverage production, and pharmaceutical manufacturing. They ensure accurate dosing of chemicals, additives, and other fluids, which is crucial for efficient and safe operations. Metering Pump
