Introduction to Low Pressure Metering Pumps

Low pressure metering pumps are essential devices in various industries, providing precise delivery of fluids at controlled flow rates. They are often used in water treatment, chemical processing, and laboratory applications, where accuracy and reliability are crucial.

Working Principle of Low Pressure Metering Pumps

Low pressure metering pumps operate on the principle of positive displacement. They deliver a fixed amount of fluid with each stroke or cycle, allowing for accurate and consistent flow rates. Typically, these pumps use a reciprocating mechanism, such as a diaphragm or piston, controlled by an electric motor or actuator.

Key Components and Their Functions

• Pump Head: The section where the fluid is contained and pressured during operation.
• Diaphragm or Piston: The moving part that creates displacement to push the fluid through the system.
• Check Valves: Prevent backflow and ensure directional flow of the fluid.
• Drive Mechanism: Converts rotary motion into reciprocating action, typically powered by an electric motor.

Performance Parameters and Numerical Analysis

Low pressure metering pumps are evaluated based on parameters such as flow rate, pressure capacity, and accuracy. Typical performance parameters include:

• Flow Rate: Capacity ranges from 0.1 to 1,000 liters per hour, depending on the application requirements.
• Pressure Range: Operates at pressures up to 20 bar for low pressure applications.
• Accuracy: Flow rate accuracy can be within ±1% of the set point, making these pumps suitable for precise metering tasks.
