By combining ProMinent’s German engineering with local expertise, we ensure solutions that are both technically reliable and operationally efficient for water treatment processes.
Metering pumps (also known as dosing pumps) are positive displacement pumps that deliver defined volumes of liquids with high accuracy. They are widely used in water treatment to inject treatment chemicals—such as coagulants, disinfectants, pH adjusters and antiscalants—into process streams at controlled flow rates.
By ensuring accurate dosing, metering pumps help improve water quality, reduce chemical waste and maintain consistent treatment performance.
ProMinent’s metering pump portfolio provides solutions for a wide range of water treatment needs:

Diaphragm metering pumps enable precise dosing of liquids and are used in water treatment, the chemical industry, and food production. They are characterized by reliability, durability, and versatility. ProMinent offers customized solutions for different requirements and processes.

No conditions are too tough for them, no application is too specialised: ProMinent solenoid-driven metering pumps work reliably within a wide performance range and are suitable for almost any liquid chemical.

Versatile: The robust yet precise technology of ProMinent motor-driven metering pumps makes them the universal solution.

Self Priming capable, ProMinent's peristaltic pumps, compliments it's range of Positive Displacement Dosing Metering Equipment. They can meter challenging fluids, such as gaseous, abrasive, shear-sensitive or high-viscosity media with ease.
