Motorized Dosing Pumps

Motorized dosing pumps, also called motor-driven metering pumps, are heavy-duty chemical dosing pumps driven by an electric motor and gearbox for continuous, reliable operation. Unlike compact solenoid pumps, motorized dosing pumps deliver higher flow rates and higher pressures, making them ideal for industrial water treatment, process dosing and agricultural fertigation systems that run for many hours every day.

In a typical design, a robust electric motor, worm gear and spring-return mechanism drive a diaphragm or plunger to inject a precise, repeatable volume of chemical on every stroke. This construction provides accurate metering across a wide capacity range and maintains stable flow even when system pressure fluctuates, helping reduce chemical consumption and ensure safe, consistent process control. Modern motor-driven dosing pumps from brands like SEKO, Etatron, ITC and ProMinent offer capacities from a few litres per hour up to several thousand litres per hour, with pressure ratings suitable for high-pressure lines, industrial processes, boilers and cooling towers. 

Motorized chemical dosing pumps are widely used for pH correction, disinfection and coagulant dosing in drinking water and wastewater treatment plants, for injection of corrosion and scale inhibitors in boiler and cooling-water circuits, and for dosing process chemicals, additives and reagents in manufacturing. In agriculture and irrigation, motor-driven dosing pumps feed fertilizers, acids and agrochemicals into drip systems and central fertigation units, while their rugged construction and IP-rated housings support reliable operation in tough field or plant environments.

When selecting a motorized dosing pump, it is important to consider required flow rate and discharge pressure, chemical compatibility, diaphragm or piston construction, motor power supply, and control options such as manual stroke adjustment, analog 4–20 mA signals or digital communication for PLC integration.
