The dosing pump can also be referred to as the metering pump in the sector. Basically these types of pumps actually function as positive displacement pumps, there are also solenoid versions. Generally, it directly injects a particular chemical substance into a gas, vapor or liquid stream over a certain period of time.

The small dosing pumps provide an extremely accurate flow rate for highly efficient controls. Dosing pumps can find a place in many points today, from wastewater treatment to food processing. In addition, agriculture, manufacturing, swimming pools, cooling towers, chemical industry and similar areas are also examples.

Dosing Pumps Working Principle

Dosing pumps inject the chemical product into the liquid stream. It is also possible to precipitate from liquids in this way. In the meantime, these special pumps are used to provide the appropriate consistency for the additives. For all these reasons, it is not difficult to say that it touches a large area. "How do dosing pumps work?" It is necessary to pay attention to some criteria in order to give a healthy answer to the question.

For example dosing pumps; It can work in different ways depending on the brand or models. Among these types, electromagnetic dosing pumps, electric motor driven pumps and non-electric dosing pumps come to the fore. On the other hand, it may be necessary to mention some special dosing systems. When the properties of all dosing pump types are examined, it will be seen that each of them actually has a specific working principle. In the light of these three types of dosing pumps, we can take a look at the principles in question.

How Do Dosing Pumps Work Without Electricity?

As the name suggests, non-electric dosing pumps do not need any electrical source, they are a solution for precise dosing and mixing problems from liquid to liquid. In this sense, their designs are simple and straight forward, they only work without electricity depending on the water flow, and use the water flow as the power source. However, it is very effective in terms of the result it creates. The water activates the pump, which sucks the required chemical from the tank and re-injects it into the water. Inside the pump without electricity, the chemical is mixed with water and the water pressure directs the desired proportioned chemical to the outlet. Once set, no action or external control is required for the pump. Regardless of the flow and pressure changes that may occur in the main water line, the concentration amount will be directly proportional to the volume of water entering the non-electric dosing pump. High dosage sensitivity eliminates all overdose risks and related problems and enables a healthy application.

Especially installation and commissioning processes of non-electric dosing pumps are very practical. Different material structures compatible with different chemicals are used in non-electric dosing pumps.

Electric Motor Driven Dosing Pumps

Looking at the way of working; It is known that dosing pumps suck and trap a certain volume of chemical from the reservoir in a certain period of time. As a result, it fulfills its duty by injecting the chemical at the desired point in the specified amount. It is effective to do this with motor driven dosing pumps; As the name suggests, such diaphragm or reciprocating dosing pumps operating with standard electric motors have high operating capacities. It can be said that the electric motor dosing pump is more durable, long-lasting and heavy-duty compared to other dosing pumps. When necessary, the advanced control system can be adapted and easily made compatible with automation.

Electromagnetic Dosing Pumps

 Electromagnetic dosing pumps, which are another type of dosing pump, differ sharply from other types with their working principle. These types of pumps are very popular today and are reminiscent of diaphragm dosing pumps in terms of operation. The point where it leaves is that the solenoid magnet gives the power of the diaphragm movement. Therefore, it is ensured that a magnetic field is created with electrical energy. As a result, the motion of the diaphragm connected to the solenoid coil creates the motion. This whole process allows chemical dosing to occur.
