Digital Chemical dosing Pumps

Intelligent dosing pumps are the ideal solution for any kind of complex dosing in less aggressive environments. Offering a high level of accuracy, digital dosing pumps not only reduce chemical waste, but also the energy bill.

Chemical dosing pumps are compact, positive displacement pumps that are designed to pump an extremely accurate flow rate of chemicals or other substances into a water or gas stream. 

ENGINEERIC offers a wide range of chemical dosing pumps with either hydraulic, mechanical, or solenoid technologies. With a wide range of material and drive options, they suit a wide range of applications including chemical transfer, oil & gas, petrochemical, and many others.

Some advantages of our chemical dosing pumps are:

  • Wide range of technologies and materials to handle all aggressive & corrosive liquids
  • Pressures up to 276 bar (hydraulic)  10 bar (mechanical)  15 bar (solenoid)
  • High viscosities – up to 5000 CPS
  • Standard IEC motor frames to allow for any motor specification (hydraulic & mechanical)
  • Options include automatic speed/stroke control

These dosing pumps work by taking a certain amount of liquid into the chamber and inserting the chemical into pipes or tanks that harbor the fluid that is being dosed. The pump is energized mainly by electric motors or an aeration-actuating element and utilizes a controller than navigates the pumps (controls flow rate) and switches the power on and off.

What are Chemical Dosing Pumps?

A chemical dosing pump is made to handle extreme conditions, including high temperatures and high pressures. A dosing pump works with a predetermined volume of water into its reservoir and infuses it into a tank or pipe containing the water until it is ready to be dosed.

Chemical Dosing Pumps

Chemical dosing pumps are positive displacement pumps that draw a measured amount of liquids into their chamber and inject into a process. Dosing pumps are also termed Metering Pumps. Technically, dosing pumps can be classified into four types i.e. electromagnetic diaphragm dosing pumps, hydraulic diaphragm dosing pumps, plunger dosing pumps, and peristaltic dosing pumps

1. Chemical Dosing Pumps in Pakistan
Chemical dosing/ metering pumps are oscillating displacement pumps. An exactly defined volume of liquid is drawn into the displacement body on the reciprocal stroke and forced into the metering line on the compression stroke.

We supply all kinds of Chemical dosing Pumps in Pakistan available in stock. We provide high-quality chemical dosing pumps or metering pumps in Pakistan We deal in all kinds of low pressure, high pressure, low flow rate, high flow rate dosing pumps in Pakistan.

Parts of a Chemical Dosing System

The main components of a Chemical dosing pump include:

  • Chemical Container or Tank – holds the product to be dosed.
  • Pump – varies in materials and size; includes an inlet, suction line, and dosing line.
  • Injector – one-way valve where the chemical is injected into product; overcomes pressure in the pipe and allows chemical into liquid flow.
  • Foot Valve – one-way valve attached to the suction line; placed into product drum and keeps the pump primed.
  • Dosing Line – rigid tube or reinforced hose; can be PE, PVC, or stainless steel for high-pressure use.
  • Control System – Ensures accuracy; turns on and off at specific times. Can be a simple flow switch or timer, up to a SCADA central control system for various sensors, and the ability to integrate into a larger system.


Examples of Dosing Pump Applications

In addition to water treatment and food industries, dosing pumps, also known as chemical metering pumps, are used in industrial plants, agriculture, manufacturing facilities, medical laboratories, and mining operations.

A chemical feed pump might be used to add a caustic chemical or an acid to a water storage tank to neutralize the pH. It can also be used as a chlorine pump to kill bacteria. A chemical dosing pump is designed to operate in challenging situations, such as high temperature and high-pressure environments.

How Does a Dosing Pump Work?

A dosing pump draws a measured amount of liquid into its chamber and injects the chemical into a tank or pipe that contains the fluid that is being dosed. It’s powered by an electric motor or an air actuator and has a controller that turns the pump on and off and manages the flow rate. Some models include more sophisticated control systems.

A dosing pump is therefore a precision instrument for accurately feeding a determined amount of liquid into a process.

Chemical dosing pumps offer repeated accuracy of operation, often in combination with sensors, to enable the pump to adjust its speed and/or stroke length in response to changing chemical conditions in the industrial process.

Ideally, a dosing pump can handle a wide range of highly corrosive, volatile, or toxic chemicals. However, depending on the application there is scope for economizing on materials and on pump design to maximize efficiency.

Chemical dosing pumps are very commonly used by engineers in a range of industries from water treatment to process, OEM to effluent, agriculture, livestock, leisure, vehicle wash, and more. Essentially, dosing procedures are adopted whenever chemical treatment is involved

Types of Chemical Dosing Pumps

These four dosing pump types are designed for different pressures, chemicals, and applications. They vary by pumping action and mechanism.

Diaphragm (constant injection) pumps use a diaphragm, piston, and valves on both the inlet and outlet to fill and empty its chamber. Drawing in the piston fills the chamber, and a specific amount of chemical is injected at a preset speed, usually a percentage of the maximum flow rate. Certain pump models are capable of variable dosing rates.

Diaphragm (pulse injection) pumps also use the diaphragm mechanism, but instead of a constant flow rate, a solenoid coil takes in the chemical and injects it in pulses. The flow rate is the length of time between pulses. It is less accurate than the constant injection pump but is simple in design and inexpensive.

Lobe pumps let a certain volume of fluid through meshing gear impellors. It is not as accurate as a diaphragm pump and it is only suitable for high viscosity fluids that will self-lubricate to minimize wear. They’re not made for low flow rates, as it is difficult to ensure accuracy.

Peristaltic pumps are highly accurate for dosing. A flexible bent tube lets the fluid pass, and the flow is controlled by a roller that moves by way of a mechanical arm on the outside. This pushes the product in the tube into the dosing tube and main fluid stream.

2. Usage of Dosing Pumps 
Chemical dosing or ”metering pumps are specially designed to use for chemicals, Acid, Alkaline, and Water.
Best Supplier of Chemical Metering Pumps in Pakistan
Chemical Dosing Pumps and feeding / Metering pumps are oscillating displacement pumps for the dosing and feeding of liquids in all industrial fields.
3. Maximum Pressure
The maximum pressure rating of a metering pump is actually at the top of the discharge pressure range of the pump so it is guaranteed to pump against at a reasonably controllable flow rate.
4. Pressure Relief Valve 
A pressure relief valve should be placed in between to prevent over pressuring of the tubing or piping line in case the stop valve is inadvertently shut while the pump is running.
05. Quality of Dosing Pumps 
ENGINEERIC supplies Chemical dosing pumps to valuable customers. That is the reason we are the best supplier of dosing pumps in Pakistan. Even we supply diaphragm dosing pumps with a 1-year warranty
PH Control and Chemical Dosing Systems
To control the PH of Liquid there is a PH controller & PH sensor. The sensor senses the PH & Controler that is attached with the dosing pump controls the ph of that liquid.

20. How do dosing pumps work?
Depending on the brand and model, a dosing pump functions in a variety of different methods. All these methods involve taking a measured amount of a chemical and then injecting that product into a pipe or similar vessel. There are a couple of major parts to a dosing pump setup.
21. Application of Chemical Dosing Pumps

Chemical Dosing pumps have a large range of applications across a number of industries. This ranges from water treatment, agriculture, industrial, manufacturing, medical, food processing, and mining. Generally dosing pumps are set up to inject a product into a water or fluid stream to cause a chemical or physical reaction.
This may be as simple as adding an acid or caustic chemical to the water to get the pH into the desired range or adding chlorine to kill bacteria. They may be also used for other products like flocculants to make a solid settle out of a liquid or alter its properties.
