Metering pumps are widely used in various industries due to their precision in dosing liquids. These pumps are used in chemical processing, water treatment, pharmaceutical manufacturing, food and beverage industries, and many other fields that require accurate and controlled liquid delivery. In this article, we will explore the applications of different types of Dosaki metering pumps.

What are Metering Pumps Used for?

Metering pumps are designed to pump and transfer corrosive or hazardous liquids in low flow rates, ensuring precise measurements of fluid volume. They are crucial in many industrial applications, particularly in the chemical, water treatment, wastewater treatment, pharmaceutical, food, and beverage sectors.

These pumps are particularly beneficial when accurate liquid measurement is required, especially in applications where the liquid is highly corrosive or requires precise dosing before use.

Common Applications of Metering Pumps:

• Chemical dosing in the chemical industry
• Chlorine dosing in water treatment systems
• Chemical dosing in research and laboratory settings
• Pumping corrosive and abrasive chemicals, such as acids, bases, solvents, etc.
• Dosing for thick paints, adhesives, printing inks, sludge, and liquid glass
• Pumping fish oil, molasses, hot bitumen
• Dosing in the food and beverage industry, including alcohol, beer, candy, soft drinks, etc.
• Pumping cleaning agents to prevent scale buildup
• Pumping chemicals in paper production
• Cement grinding aid dosing

Applications of Diaphragm Metering Pumps

Diaphragm metering pumps are popular due to their low cost and versatility. They are ideal for pumping a wide range of liquids, particularly those with corrosive or abrasive properties. These pumps provide high accuracy, making them suitable for low-flow applications that require precision, such as chemical dosing, water treatment, and laboratory experiments.

Additionally, diaphragm metering pumps are completely sealed, preventing leaks and ensuring the safe transfer of hazardous liquids without environmental contamination. These pumps often use electric motors to provide stable and high-performance operation.

Common Applications of Diaphragm Metering Pumps:

• Dosing chemicals, alkalis, acids
• Wastewater treatment and swimming pool water treatment

Applications of Piston Metering Pumps

Piston metering pumps are known for their durability and high pressure capabilities. These pumps are traditional and suitable for a wide range of liquids, especially when high-pressure dosing is required. However, they are not ideal for highly viscous or abrasive liquids and may not be fully leak-proof.

Piston metering pumps are typically used for applications that require high-pressure and accurate dosing, such as solvent handling, glue, and paint dosing.

Applications of Magnetic Metering Pumps

Magnetic metering pumps work similarly to diaphragm pumps but use magnets to generate the energy for operation. These pumps are known for their quiet operation, energy efficiency, and safety in harsh environments, as they help reduce the risk of fires or explosions.

Common Applications of Magnetic Metering Pumps:

• Printing ink, paint, and adhesive dosing
• Solvent handling
• Wastewater treatment

Applications of Hydraulic Metering Pumps

Hydraulic metering pumps combine the advantages of both piston and diaphragm pumps. They are perfect for applications requiring leak-proof systems that handle corrosive and hazardous liquids, as well as high-pressure dosing. These pumps are particularly useful in hydraulic systems, boosting systems, and lifting platforms.

Hydraulic metering pumps can handle nearly all types of hazardous and abrasive liquids and are designed to deliver high pressure with a focus on leak prevention.

Common Applications of Hydraulic Metering Pumps:

• Dosing hazardous chemicals
• Handling chemicals with suspended solids
• High-pressure dosing applications
