What is a Dosing Pump?

Dosing pump is a pump used to inject a chemical liquid flow movement rate into a water stream. Dosing pump has a pump component that can be used as a regulator of the amount of liquid or solution to be released.

Dosing pump is one of the most commonly used types of pumps in the chemical industry, ranging from wastewater management, agriculture, factories, manufacturing to drugs to food management.

What Are the Uses of Dosing Pump?

In addition to being used for water filtration or purification and food processing, dosing pumps are also used in industrial agricultural installations, factories, health or medicine laboratories and the mining industry.


Dosing pump is typically used to add caustic or acidic chemicals to water storage tanks to neutralize pH.


Dosing pump is also often used as a chlorine pump to kill viruses and bacteria.


Certain brands are designed for more complicated situations, such as high temperature and high pressure.

How a Dosing Pump Works

Dosing pump pumps a predetermined amount of liquid or substance into the pump chamber and adds liquid to the process. The pump is driven by electric power or an air actuator and has a controller that can turn the pump on and off and regulate its flow.

Corresponding to the brand and form, the Dosing Pump & nbsp;Chemical plays a role in various working principles. All of these working principles are responsible for extracting some chemicals and then injecting them into pipes or tanks. There are several important parts for setting up a Dosing Pump.

For more details, here is a simple explanation of how the following dosing pump works:

  1. The most basic components of a dosing pump are the valve that sucks the chemical liquid from the chemical tank to be sucked, the pump, and the injector.

  2. The valve used is a one-way valve that is weighted to stay at the bottom of the chemical liquid tank to be pumped. Some brands add a float switch that functions as an alarm when the chemical liquid has run out.

  3. Connected to the valve is the pump which uses chemical resistant plastic materials such as PVC, PE, or stainless steel.

  4. Then the liquid that has been pumped from the tank will be sprayed into the flowing solvent liquid at a certain rate. After the injection valve sprays a certain amount of chemicals, the pump will automatically stop pumping. The technology used today is a valve that can spray liquid in the middle of the solvent flow so as not to cause corrosion on the walls of the channel, so that the liquid will be dissolved immediately.
