What Is Chemical Feed Pump?
Chemical Feed Pump is a pump used for metered dosing of chemicals.
They are used in the medical and research fields to accurately administer minute amounts of chemicals. They are ideal for applications where highly accurate and precise chemical dosing is required.
They are widely used in hospitals and medical institutions and are available in a wide variety of types. They are also used in the research and industrial fields when minute amounts of liquid need to be accurately injected.
Uses for Chemical Feed Pumps
Chemical Feed Pumps are widely used in the medical and research fields. The following are examples of Chemical Feed Pump applications
1. Medical Applications
Used for intravenous infusion and intravenous administration. They are ideal when high-precision and accurate drug administration is required, and are used in a wide range of situations from acute care to chronic care.
Chemical Feed Pumps may also be used for home care. Injecting drugs needed for home treatment or self-injection for diabetes and other conditions are examples.
2. Research Applications
Used to inject minute amounts of reagents or dispense drugs. It plays an important role in biochemical experiments and molecular biology research.
3. Industrial Applications
Chemical Feed Pumps are also widely used in industry. Chemical Feed Pumps are used to periodically inject chlorine-based disinfectants into cooling towers and other facilities that use circulating water to prevent the growth of bacteria. They are also used for periodic injection of paint into products and management of resin raw materials.
They are also useful in the food and cosmetics industries, and are used in a wide range of fields.
Principle of Chemical Feed Pump
Chemical Feed Pump is a device that works like a syringe, pumping out a fixed amount of fluid in a reliable manner. An internal syringe is filled with a drug, and the pump pushes the drug out to dispense a fixed amount of fluid.
Chemical Feed Pumps make it possible to precisely control the flow rate and time required to administer the drug. If the drug is administered manually, errors can occur, resulting in an increase or decrease in the amount of drug administered.
Quantitative measurement of drugs can be achieved by stepper motors/servomotors or by control with a controller. In some cases, control is achieved by mechanical volume and frequency of operation, such as diaphragms.
Types of Chemical Feed Pumps
There are two main types of Chemical Feed Pumps: manual and electric. Manual pumps use a valve or plunger to inject chemicals, while electric pumps use a motor to inject chemicals. The electric type is widely used in industrial applications.
There are also two types based on structure: variable displacement type and fixed displacement type. The variable displacement type can adjust the amount of chemicals injected. Fixed-displacement pumps, on the other hand, are used for regularly dosing a fixed amount of medicine.
How to Choose a Chemical Feed Pump
Chemical Feed Pumps require accuracy and safety, so care must be taken in their selection. First, select the capacity of the Chemical Feed Pump according to the amount of drug required.
The appropriate pump type for the drug should also be selected. It is also important to consider the corrosiveness, viscosity, and safety of the drug.
In the event of drug leakage, the health of workers and other personnel may be seriously affected. Therefore, products with safety features such as an overdose prevention function and a stop function in the event of an abnormality should be considered.
In addition, ease of use and maintainability of the pump are also key points in the selection process. Pumps designed for easy operation by operators and pumps that are easy to disassemble and clean are often selected.

How to Use Chemical Feed Pumps
Chemical Feed Pumps may need to be degassed because air can become trapped in them during the hot summer months, making it impossible to pump liquid. If the pump has an air release plug, open it to release air.
In some cases, if the inside is dirty or chewed up, disassembly and cleaning may be necessary. During disassembly, it is safe to wear protective equipment such as rubber gloves and safety glasses, as chemicals may remain.
Scale and debris can cause injection failure, so it is important to clean the parts thoroughly without damaging them.
