Dosing Pumps
A dosing pump, which is a positive displacement pump, is designed to inject a chemical or another substance into a flow of water, gas or steam. Dosing pumps, which are typically small, provide an extremely precise flow rate for maximum control. They are the central part of an integrated dosing system designed for automatic dispersion of chemicals. This dosing definition applies to a wide range of applications and industries, from waste water treatment to food processing.
A dosing pump draws a measured amount of liquid into its chamber and injects the chemical into a tank or pipe that contains the fluid that is being dosed. It’s powered by an electric motor or an air actuator and has a controller that turns the pump on and off and manages the flow rate. Some models include more sophisticated control systems.
