Metering Pump Vs Dosing Pump

Metering pumps and dosing pumps are both types of positive displacement pumps used for accurate and precise fluid handling in various industrial applications. They are designed to deliver fluids in a controlled and measured manner. However, there are some differences:Metering Pump Vs Dosing Pump


Metering Pump: Metering pumps are primarily used to continuously deliver a specific flow rate of fluid, often for processes that require precise and consistent dosing over an extended period. They are commonly used in water treatment, chemical manufacturing, and other applications where maintaining a specific flow rate is critical.

Dosing Pump: Dosing pumps are designed for delivering a specific quantity of fluid at specific intervals or in batches. They are commonly used for adding chemicals or additives in processes that require periodic, controlled injections of a fluid, such as in wastewater treatment, food and beverage production, and pharmaceutical manufacturing.

Flow Rate:

Metering pumps are designed to provide a continuous and consistent flow rate over an extended period, and they are capable of handling higher flow rates. This makes them suitable for applications where maintaining a precise and constant flow rate is essential, such as in various industrial processes.

Dosing pumps, on the other hand, are typically used for delivering fluids in discrete and controlled doses that can be adjusted to meet specific application requirements. They are better suited for low to moderate flow rates and are often used in situations where precise dosing of chemicals or additives is necessary but not necessarily at a high continuous flow.

Control and Precision:

Metering pumps excel at maintaining a specific flow rate with a high degree of accuracy and precision, making them essential for applications where even minor variations in flow rate can be critical to the process's success. They are often used in scenarios where maintaining a consistent flow rate is crucial, such as chemical manufacturing or water treatment.

Dosing pumps are specifically designed for precise dosing, allowing users to adjust and control the amount of fluid delivered with each cycle. This feature makes dosing pumps highly accurate in delivering fixed volumes of liquid, making them ideal for applications where precise and controlled chemical or additive dosing is required. Dosing pumps are commonly used in industries like pharmaceuticals, agriculture, and wastewater treatment, where measured chemical addition is essential.


Metering Pump: Common applications include chemical injection, pH control, disinfection, and maintaining specific chemical concentrations in a continuous process.

Dosing Pump: Dosing pumps are used for adding precise amounts of chemicals, reagents, or additives in batch processes, such as in food and beverage production, pharmaceutical manufacturing, and laboratory settings.

Pumping Mechanism:

Metering Pump: Metering pumps can use various mechanisms, including diaphragm pumps, piston pumps, and peristaltic pumps. They are designed for long-term, continuous operation.

Dosing Pump: Dosing pumps often use diaphragm pumps or peristaltic pumps, which are well-suited for intermittent and accurate dosing.

Control and Monitoring:

Metering Pump: Metering pumps typically offer advanced control and monitoring options, including feedback loops, external control systems, and the ability to adjust the flow rate based on real-time feedback.

Dosing Pump: Dosing pumps may have basic control options for adjusting the dose size and dosing frequency. They are often set up for periodic or batch dosing.

the choice between a metering pump and a dosing pump depends on the specific requirements of your application. If you need a continuous and precise flow rate, a metering pump is more suitable. For applications that require intermittent and precise dosing of chemicals or additives, a dosing pump is the better choice.
