Dosing Pump
In industries where accuracy, safety, and efficiency are critical, the dosing pump plays a vital role. A dosing pump is a specialized type of pump designed to inject precise amounts of chemicals or liquids into water, gas, or other fluid streams. These pumps are widely used in water and wastewater treatment, chemical processing, pharmaceuticals, food & beverage manufacturing, and the oil & gas industry.
Accurate dosing ensures that processes remain efficient, cost-effective, and environmentally safe. For example, in a water treatment plant, a small error in dosing chemicals like chlorine or antiscalants can affect water quality and plant performance.
At Dosimix Technologies, we are a trusted dosing pump manufacturer and supplier in India with more than two decades of expertise. We provide high-quality, energy-efficient, and durable dosing solutions tailored to industrial requirements. Whether you are looking for a chemical dosing pump, water treatment dosing pump, or automatic dosing pump, Dosimix offers the best dosing pumps in India designed for reliability and performance.
What is a Dosing Pump?
A dosing pump is a positive displacement pump that delivers a controlled flow of chemicals or liquids into a process stream. Unlike regular pumps, dosing pumps are designed for accuracy and consistency, ensuring the right amount of liquid is injected at the right time.
In simple terms:
- A dosing pump injects chemicals into water, gas, or another fluid.
- It ensures precise chemical treatment for industrial processes.
- It prevents wastage, improves safety, and increases process efficiency.
Types of Dosing Pumps
At Dosimix Technologies, we manufacture a wide range of dosing pumps to meet diverse industry requirements. Our key offerings include:
Hydraulically Actuated Diaphragm Pump
- Suitable for high-pressure applications.
- Ensures leak-proof dosing without direct contact between liquid and moving parts.
- Ideal for aggressive chemicals.
Plunger Dosing Pump
- Uses a reciprocating plunger mechanism.
- Provides high accuracy and is suitable for handling viscous fluids.
- Best for applications requiring industrial dosing pumps with consistent output.
Mechanically Actuated Diaphragm Pump
Available under two series:
- DMM Series – Compact, robust, and cost-effective.
- Accudo Series – Advanced design, high efficiency, and low maintenance.
Working Principle of a Dosing Pump
The operation of a dosing pump is simple yet precise.
Step-by-step working:
- Suction Stroke – The pump diaphragm or plunger moves back, creating a vacuum that draws the chemical from the tank into the pump head.
- Compression Stroke – The diaphragm/plunger pushes forward, forcing the chemical into the discharge line.
- Check Valves – Inlet and outlet check valves ensure one-way movement of fluid, preventing backflow.
- Control Mechanism – Flow rate is adjusted by stroke length or speed, ensuring accurate dosing.
This controlled operation guarantees accuracy and reliability, even under continuous industrial use.
Applications of Dosing Pumps
Dosing pumps are widely used across industries. Some key applications include:

FAQs
A dosing pump is a positive displacement pump designed to inject a precise volume of liquid or chemical into a process stream. It works in a simple cycle:
- Suction stroke – The pump draws chemical from a tank.
- Compression stroke – The chemical is pushed into the pipeline.
- Check valves – Prevent backflow and ensure accuracy.
This makes dosing pumps ideal for water treatment, chemical processing, pharmaceuticals, food & beverages, and oil & gas industries.
The most common types of industrial dosing pumps are:
- Hydraulically Actuated Diaphragm Pump – Best for high-pressure, leak-proof applications.
- Plunger Dosing Pump – Suitable for viscous fluids with high accuracy.
- Mechanically Actuated Diaphragm Pump – Cost-effective, reliable, and widely used in water treatment.
In water & wastewater treatment plants, a dosing pump is used to inject chemicals like chlorine, antiscalants, coagulants, and pH adjusters. This ensures:
- Safe and clean drinking water
- Prevention of scaling and corrosion in pipelines
- Stable pH levels for industrial water processes
To select the right dosing pump manufacturer solution, consider:
- Type of chemical (corrosive, viscous, or abrasive)
- Required flow rate and pressure
- Pump material compatibility (SS316, PTFE, PVC, etc.)
