Chemical Metering Pumps

A chemical metering pump, also known as a dosing pump or a chemical injection pump, is a device used to precisely and consistently deliver a specific volume of chemical substances into a fluid stream. These pumps are commonly used in various industrial, chemical, water treatment, and process control applications where accurate dosing of chemicals is essential.
