Dosing Pumps

Dosing pumps are designed to inject a specific amount of liquid into a system in a precise and controlled manner. By adjusting the flow rate and stroke frequency, the desired amount of liquid is dosed at the correct rate. Different pump technologies (e.g., diaphragm, piston, or peristaltic types) are used in dosing and metering applications, each offering advantages in terms of precision, chemical resistance, and process requirements. Thanks to these features, dosing pumps are widely preferred in water treatment, chemical, food, pharmaceutical, and industrial processes.
