Pumpbiz is a worldwide distributor of pumps including chemical dosing pumps. Dosing pumps, or metering pumps, are positive displacement pumps designed to deliver a precise amount of chemicals or substances into a flow of fluid or gas. There are a number of ways a dosing pump delivers a chemical or other product, but it generally involves a specific amount being drawn into a chamber and then injected into a pipe or tank.
