1. Introduction to Chemical Liquid Metering Pumps

Chemical liquid metering pumps, also known as dosing pumps, are precision instruments used in various industries to dispense and control the flow of chemicals. These pumps are designed to deliver fluids at adjustable flow rates, ensuring accurate and consistent dosing. They are essential in processes that require precise chemical mixing and infusion.

2. Principle of Operation

Chemical liquid metering pumps operate based on a simple yet effective mechanism involving a reciprocating diaphragm or piston. When the pump is activated, the diaphragm or piston moves back and forth within a chamber, creating a vacuum that draws the chemical into the pump head during the intake stroke. The subsequent discharge stroke pushes the liquid out at a controlled flow rate. This action ensures accurate volumetric dosing with minimal pulsation. Common materials used in construction include stainless steel, PVC, and Teflon to withstand various chemical properties.

3. Applications of Chemical Liquid Metering Pumps

Meting pumps are utilized in a wide range of applications across different industries, including:

• Water and Wastewater Treatment: For dosing disinfectants and conditioning chemicals.
• Oil and Gas: For injecting corrosion inhibitors and process additives.
• Food and Beverage: For precise flavoring and ingredient addition.
• Pharmaceuticals: For accurate formulation and delivery of active pharmaceutical ingredients.

4. Technical Specifications

Key parameters in selecting a chemical liquid metering pump include:

• Flow Rate: Ranges from 0.1 mL/min to 1000 L/h, depending on application needs.
• Discharge Pressure: Capable of handling pressures from 5 bar up to 400 bar.
• Temperature Range: Operates efficiently within -10°C to 100°C.
• Viscosity: Suitable for fluids with viscosities ranging from 0.5 to 20,000 centipoises.
