Understanding Micro Peristaltic Pumps

1.Peristaltic Pump Working Principle

Micro peristaltic pumps utilize a flexible tube or hose and a series of rollers or shoes to create a positive displacement mechanism. As the rollers or shoes rotate, they compress the tube, propelling the fluid in a controlled manner. This gentle pumping action ensures that the fluid remains uncontaminated and unaltered, making micro peristaltic pumps suitable for sensitive applications.

2.Characteristics of Micro Peristaltic Pumps:

  • Compact and lightweight design, making them suitable for space-constrained environments.
  • Precise flow rate control, allowing for accurate dosing and metering of fluids.
  • Non-contact pumping mechanism, ensuring compatibility with a wide range of fluids, including corrosive or shear-sensitive materials.
  • Easy tube replacement, minimizing downtime and reducing the risk of contamination.
  • Low maintenance requirements, with minimal components that are easy to clean and sterilize.

The Power of peristaltic pump 12v Supply

1.Advantages of 12V Power Supply:

Micro peristaltic pumps are often designed to operate on a 12V power supply, which provides several benefits:

  • Portability: A 12V power supply allows for greater mobility, making the pumps suitable for field applications or situations where a standard power source may not be readily available.
  • Ease of Use: The 12V power supply is commonly used in many electronic devices, making it convenient and accessible for various applications.
  • Energy Efficiency: Operating at 12V reduces power consumption, making the pumps more energy-efficient and cost-effective in the long run.

When using micro peristaltic pumps with a 12V power supply, it is essential to consider:

  • Power Source: The power supply can be obtained from batteries, power adapters, or other portable energy sources, depending on the specific requirements of the application.
  • Voltage Regulation: To ensure consistent and reliable pump operation, voltage regulators may be employed to stabilize the voltage and protect the pump from voltage fluctuations.

Flow Rate Pump Control

1 Factors Influencing Flow Rate pump:

Several factors impact the flow rate control of micro peristaltic pumps:

  • Tube Diameter: The inner diameter of the tube affects the flow rate, with larger diameters allowing for higher flow rates.
  • Roller Speed: Adjusting the rotational speed of the rollers or shoes alters the flow rate. Higher speeds result in faster flow rates, while slower speeds reduce the flow rate.
  • Tube Compression: Changing the degree of tube compression by adjusting the roller pressure or shoe position impacts the flow rate. Increased compression leads to higher flow rates, while reduced compression results in slower flow rates.
  • Fluid Viscosity: Fluids with higher viscosities require more force to be pumped, resulting in lower flow rates.

2.Flow Rate Measurement and Calibration:

Accurate flow rate measurement and calibration are crucial for precise fluid delivery. Various methods, such as flow sensors or timed delivery, can be employed to measure and calibrate the flow rate of micro peristaltic pumps. Regular calibration ensures the reliability and accuracy of the pump’s performance.

Applications of Micro Peristaltic Pumps

Micro peristaltic pumps find applications across numerous industries, including:

  • Medical and Pharmaceutical: Precise medication dosing, drug delivery systems, and laboratory processes.
  • Analytical and Research: Sample handling, reagent delivery, and liquid chromatography.
  • Food and Beverage: Flavoring and ingredient dispensing, dosing additives, and quality control.
