A Dosing Pump is a small, positive displacement pump. Dosing Pump is designed to pump a very precise flow rate of a chemical or substance into either a water, steam, or gas flow. A Dosing Pump will deliver this precise flow rate of substance or other product by a number of dissimilar methods but it normally involves drawing a measured amount into a chamber and then injecting this volume of the chemical into the pipe or tank being dosed. Dosing Pump is used in a variety of applications from agriculture, industry, manufacturing to medicine.
A Dosing Pump is generally quite small and is powered by either a little electric motor or air actuator. They are controlled either by an external control system or more normally an internal pump controller that can alter the flow rate, the on/off function, and also things like alarms and warnings for run dry, degassing, and low product levels.
A Dosing Pump is used to add small but accurate volumes of a liquid to other fluid streams or vessels. Metering is achieved by controlling the Dosing Pump speed or stroke length to achieve a precise delivery rate or by controlling the period of operation to supply an accurate single dose.
