Chemical Dosing Applications

Chemical Feed Pumps, also known as Chemical Dosing Applications, are small positive displacement pumps that accurately inject chemicals or other substances into water, gas, or steam. Chemical dosing application is typically part of a chemical supply system that includes one or more pumps, storage tanks, plumbing, and control panels. Chemical Dosing pumps are normally modest, but they give a very accurate flow rate for optimal control.

They are the heart of an integrated dosing system for automated chemical dispersion from wastewater treatment to food processing, this dosage concept applies to a wide range of applications and industries. Dosing pumps, also known as chemical dosing pumps, are utilized in industrial plants, agriculture, manufacturing facilities, medical labs, and mining activities, in addition to water treatment and food processing.

To neutralize the pH of a water storage tank, a chemical dosing pump can be used to supply a caustic chemical or an acid. It may also be used to destroy microorganisms as a chlorine pump. A chemical dosing pump is intended to work in extreme conditions, such as high temperatures and high pressures.

A dosing pump pulls a predetermined volume of liquid into its chamber and injects it into a tank or pipe containing the fluid to be dosed. It’s driven by an electric motor or an air actuator, and it features a controller that controls the flow rate and turns the pump on and off. Some versions come with more advanced control systems.


The product to be dosed is held in a chemical container or tank.

Pumps come in a variety of materials and sizes, including inlets, suction lines, and dosing lines.

INJECTOR — a one-way valve that permits the chemical to be injected into the product while also overcoming pipe pressure and allowing the chemical to flow into the liquid.

FOOT VALVE – a one-way valve that is connected to the suction line and is put in the product drum to keep the pump primed.

DOSING LINE — rigid tube or reinforced hose; for high-pressure application, PE, PVC, or stainless steel can be used.

CONTROL SYSTEM – Ensures precision by turning on and off at predetermined periods. It might be anything from a basic flow switch or timer to a SCADA central control system with the capacity to link into a bigger system.


Dosing Pumps have a wide range of applications in many industries. This extends to water treatment, agriculture, industry, manufacturing, medicine, food processing, and mining. In general, dosing pumps are set up to inject a product into a stream of water or liquid to initiate a chemical or physical reaction.

This is as easy as adding an acid or a harsh chemical to water to bring the pH to the desired range or adding chlorine to kill the bacteria. You can also use other products, such as flocculants, to precipitate solids from liquids or change their properties.

Dosing can also be used to administer a chemical to a stream to make a product. It can be used for manufacturing etc. B. Ensure regular consistency of adhesives or additives in the manufacture of fibrous plates and ensure consistent quality of brine for meat production.

Dosing pumps can also be used in high-pressure and high-temperature applications, such as weighing kettle containers using anti-corrosion or anti-scaling agents, or catalysts in the pot.
