Different types of pumps are used in industries or factories for injecting chemicals or fluids. Chemical dosing pumps are designed for injecting reagents, chemicals, or substances into gas, water, or steam. These pumps are smaller in size and provide a good flow rate for higher control. The pumps are designed to be used in tough situations where the temperature is high or in high-pressure environments. The automatic dispersion of chemicals is possible through the central part of a systems integration. A wide range of applications makes use of chemical dosing pumps in every industry. They are used for wastewater treatments in various industries such as industrial plants, agriculture, manufacturing units, medical laboratories, and various other operations. Where the PH level of water has to be neutralized, chemical feed pumps are used to add acid or caustic chemicals to the tanks storing water. The chemical dosing pumps are also used for adding chlorine solutions to kill bacteria.
Chemical metering pumps are used to move a certain amount of fluid or liquid into a chamber in a specified time. Chemical treatment plants, water treatment plants, agricultural applications make use of such pumps. It's important to select the best one according to the requirement and usage. The material used in making such pumps are resistant to corrosion, abrasion, and stickiness or viscosity. Chemical dosing pumps are also chemical metering pumps as some applications require exact measurements and volumes of chemicals. Hence chemical dosing pumps are also known as chemical metering or chemical feeding pumps. Chemicals like sulfuric and hydrochloric acid tend to corrode the material. Also, there are chlorine, alkaline and water that tend to corrode the pumps. Hence selection has to be done keeping in mind the use and its compatibility. Many Chemical dosing pump manufacturers or dosing pump manufacturers may not get into the detail and might focus on selling the product. Expert advice is recommended here while choosing the chemical pump. A precise measurement or the use should be known before using the application for different situations. Diaphragm pumps, peristaltic pumps, and lobe pumps are different types of dosing pumps. In diaphragm pumps, there are two types – a constant injection pump and a pulse injection type pump.
Diaphragm pumps make use of diaphragm, pistons, and valves on inlet and outlet to top up as well as to drain the chambers. When the piston is drawn in the chamber fills with a specific amount of chemical at a certain speed. The second type of pulse injection pumps also make use of a diaphragm mechanism where a solenoid coil takes the injection and injects it into the pulses. The pulse injection pump is not expensive and less accurate than the constant injection pump.
Lobe pumps have meshing gear impellers wherein a fixed amount of liquid is sent through the impellers. Fluids having high viscosities are sent through such pumps. The flow rates should be low or minimum.
Peristaltic pumps are accurate for dosing chemicals. A bent tube that is very flexible is used for passing the chemical fluids. The flow is managed by a mechanical arm on the outside. The product in the tube is pushed into the dosing tube.
The working of the chemical dosing pump happens with the different components. The chemical dosing pump is designed with various components for its function. The main components are:-
Chemical tank: - A tank works as storage to hold material to be dosed.
Dosing pump; - It includes a dosing line, suction line, and an inlet. There are different sizes of dosing pumps and varieties of materials as per the application. A dosing line is a tube that is of PE, PVC, or stainless steel material. It is used for high-pressure situations.
Injector: - As the name suggests, they are used to inject the chemicals into the flow.
Foot valve:- This is a one-way valve attached to the suction line. It is placed in the drum
Control system: - The control systems are highly advanced nowadays which helps in smooth functioning. They check the accuracy at different times.
A certain amount of liquid is drawn which is measured by the dosing pump into its chamber. Later a chemical is injected by the pump into the tank or pipe containing the fluid. The pump works with an air actuator or electric motor. The pump is turned on and off with the help of a controller. The flow rate of the liquid is managed by the controller. The control systems in different pumps are different and thus the models are selected.
