How to Use 313KB Peristaltic Pump: Examples, Pinouts, and Specs

The 313KB Peristaltic Pump is a precision fluid movement device commonly used in medical, laboratory, and industrial settings. This pump operates by mechanically compressing a length of flexible tubing, thus propelling the fluid within the tube along in a controlled manner. The design ensures that the fluid only contacts the tubing, not the pump mechanism, which is ideal for sterile applications or when handling aggressive chemicals.

• Medical infusion pumps
• Laboratory experiments requiring precise fluid control
• Industrial processes involving corrosive or sensitive liquids
• Hydroponic systems for nutrient delivery
• Aquarium dosing pumps

• Voltage: 12V DC
• Current: 500 mA
• Power Rating: 6W
• Flow Rate: 0-100 mL/min
• Tubing Internal Diameter: 2.5 mm
• Operating Environment: 0-40°C, <80% RH

1. Power Connections: Connect the positive voltage (V+) pin to a 12V DC power supply, and the ground (GND) pin to the common ground in your circuit.
2. Tubing Installation: Insert the flexible tubing into the pump ensuring a secure fit to prevent leaks.
3. Priming the Pump: Before the first use, prime the pump by running it with water to ensure no air is trapped in the system.
4. Control: Use a microcontroller, such as an Arduino UNO, to turn the pump on and off. You can control the flow rate by using pulse-width modulation (PWM) or by controlling the duration the pump is on.

• Avoid running the pump dry, as this can damage the internal components.
• Ensure the tubing is properly seated and secured to prevent leaks.
• Use a relay or a motor driver to interface the pump with a microcontroller to protect the microcontroller from current spikes.
• Regularly check and replace the tubing as it wears out over time due to the mechanical action of the pump.

// Define the control pin
const int pumpPin = 3; // Connect the pump control wire to pin 3

void setup() {
  pinMode(pumpPin, OUTPUT); // Set the pump control pin as an output
}

void loop() {
  digitalWrite(pumpPin, HIGH); // Turn on the pump
  delay(1000); // Run the pump for 1 second (1000 milliseconds)
  digitalWrite(pumpPin, LOW); // Turn off the pump
  delay(1000); // Wait for 1 second
}

• Pump does not start: Check power supply connections and ensure the voltage is 12V DC.
• Insufficient flow rate: Verify that the tubing is not kinked or clogged and that it is properly seated in the pump.
• Pump is noisy or vibrating excessively: Ensure the pump is mounted securely and that the tubing is not causing tension.

• If the pump does not operate, double-check all electrical connections and ensure the power supply is functioning.
• For flow rate issues, inspect the tubing for blockages or damage and replace if necessary.
• Excessive noise or vibration can often be remedied by re-securing the pump and ensuring the tubing is free to move as the pump operates.

Q: How long can the pump run continuously? A: The pump is designed for intermittent use. Continuous operation should be limited to avoid overheating and to prolong the life of the pump.

Q: Can the pump handle viscous fluids? A: Yes, but the flow rate may be reduced depending on the viscosity of the fluid. Ensure the tubing is rated for the specific fluid you are pumping.

Q: Is the pump reversible? A: No, the 313KB Peristaltic Pump is not designed to reverse its direction. Fluid will only flow in one direction.
