How to Use degasing pump: Examples, Pinouts, and Specs

A degassing pump is a specialized device designed to remove dissolved gases from liquids. This process is crucial in various applications to ensure the purity and effectiveness of the liquid. Common use cases include water treatment, chemical processing, and laboratory equipment. By eliminating dissolved gases, the degassing pump helps prevent issues such as oxidation, foaming, and inaccurate measurements in sensitive applications.

Below are the key technical details and pin configuration for the degassing pump:

1. Power Supply: Connect the VCC pin to a 12V DC power supply and the GND pin to the ground.
2. Liquid Connections: Attach the liquid inlet to the source of the liquid to be degassed and the outlet to the destination container.
3. Control Signal: If speed control is required, connect the CTRL pin to a PWM signal from a microcontroller like an Arduino UNO.

• Ensure Proper Sealing: Make sure all connections are properly sealed to prevent leaks.
• Avoid Dry Running: Do not run the pump without liquid as it may damage the internal components.
• Temperature Range: Operate the pump within the specified temperature range (0°C to 50°C) to avoid overheating.
• Flow Rate: Monitor the flow rate to ensure it does not exceed the specified 0.5 L/min.

Below is an example code to control the degassing pump using an Arduino UNO:

// Define the control pin for the pump
const int pumpControlPin = 9;

void setup() {
  // Initialize the control pin as an output
  pinMode(pumpControlPin, OUTPUT);
}

void loop() {
  // Set the pump speed using PWM (0-255)
  analogWrite(pumpControlPin, 128); // 50% speed
  
  // Run the pump for 10 seconds
  delay(10000);
  
  // Stop the pump
  analogWrite(pumpControlPin, 0);
  
  // Wait for 5 seconds before restarting
  delay(5000);
}

1. Pump Not Starting: Ensure the power supply is connected correctly and providing 12V DC.
2. Low Flow Rate: Check for blockages in the inlet or outlet and ensure the liquid source is sufficient.
3. Overheating: Verify that the pump is operating within the specified temperature range and not running dry.

• Check Connections: Ensure all electrical and liquid connections are secure and correct.
• Monitor Power Supply: Use a stable power supply to avoid voltage fluctuations.
• Regular Maintenance: Clean the pump and check for wear and tear regularly to maintain optimal performance.

By following this documentation, users can effectively utilize the degassing pump in their applications, ensuring reliable and efficient operation.
