1. Introduction: Why Is Precision Important in the Industrial World?

In modern industrial processes, millimeter accuracy is no longer a luxury, but a necessity. In the chemical, water treatment, food and pharmaceutical sectors, mixing liquids in the right proportions directly affects product quality and process safety. This is where dosing pumps come into play. In this article, we will examine step by step how dosing is done with a dosing pump.

2. What is a Dosing Pump? Basic Definition and Function

A dosing pump is a special type of pump used to transport liquids in specific and precise proportions or to inject them into another fluid. It is generally preferred for low-flow but high-precision applications. The flow rate and volume of the pumped liquid can usually be adjusted with electronic control systems.

3. What is Dosing and Why is it Necessary?

Dosing is the process of adding a liquid to another substance in certain proportions. For example; When dosing chlorine in a water treatment plant, the exact right amount of chlorine must be added to the water. While insufficient dosage reduces the cleaning effect, excessive dosage can put systems and health at risk. This is where dosing pumps come into play.

4. How to Dosage with a Dosing Pump?

This process consists of several basic steps:

• Step 1: Making Input and Output Connections

The pump's suction hose is connected to the tank containing the liquid to be dosed. The output hose is directed to the target medium, such as a water line or reactor.

• Step 2: Calibration Setting

The pump's flow rate and dosage amount are adjusted from the control panel on the pump or via the automation system.

• Step 3: Operation and Monitoring

When the system is started, the pump sucks the liquid and delivers it to the target point at the desired rate. Flow sensors are used to monitor dosage accuracy.

5. Which Systems Are Integrated With?

Dosing pumps are generally integrated with the following systems:

• PLC Automation Systems

These systems monitor pump data and automatically update the dosage amount when necessary.

• pH and ORP Measurement Devices

These devices monitor whether the chemical added to the water affects the pH balance.

• Flow Control Panels

It monitors whether the flow rate remains constant and generates an alarm when necessary.

6. Things to Consider During the Dosing Process

The following factors are of great importance for correct dosing:

• Viscosity of the Chemical: The density of the fluid plays a critical role in selecting the pump.

• Environmental Conditions: Temperature and pressure changes can affect dosage accuracy.

• Pump Diaphragm and Material Compatibility: A material resistant to the chemical used should be selected.

7. What to Consider When Selecting a Dosing Pump?

There is no single solution for every dosage need. When selecting a pump, the following elements should be considered:

• Flow Range and Pressure Capacity

• Chemical Compatibility

• Control Type (Manual, Digital, Analog, PLC Compatible)

• Energy Consumption and Efficiency

8. Application Examples with Dosing Pumps

• Water Treatment Plants: Dosing of substances such as chlorine, pH regulator, coagulant.

• Food Production: Dosing of flavors, additives and preservatives.

• Pharmaceutical Industry: Mixing of active ingredients with precise ratios.

• Petrochemicals: Injecting additives and inhibitors with correct ratios.

These examples show how critical a role dosing pumps play in the industry.

9. Result: Correct Dosage, Successful Process

Thanks to dosing pumps, precise dosing processes have now become much safer, more efficient and controllable. These pumps not only transport chemical liquids; they also increase production quality, reduce costs and protect human health.

Remember, for a successful dosing system, regular monitoring of the process is as vital as correct pump selection and installation.
