Dosing pumps, also a type of positive displacement pump, are designed to inject precise amounts of fluid into a process. These pumps are widely used in applications requiring exact fluid dosing Dosing pumps use a motor-driven mechanism to push a set amount of liquid into a delivery line. This process is controlled by a timer or flow meter, ensuring accuracy. The common designs include diaphragm, peristaltic, and piston-driven dosing pumps.
