How to Choose the Components of the Peristaltic Pump System?

The peristaltic pump system consists of three parts: the peristaltic pump driver, the peristaltic pump head, and the peristaltic pump tubing.

Ⅰ. The choice of peristaltic pump tubing

1. As the condition of the peristaltic pump hose;

2. The peristaltic pump tubing must have a certain degree of flexibility, that is, the hose can quickly recover its shape after being compressed in the radial direction;

3. Has a certain degree of wear resistance;

4. The tubing of the peristaltic pump must have a certain ability to withstand pressure;

5. No leakage (good air tightness);

6. Low adsorption, good temperature resistance, not easy to aging, no swelling, corrosion resistance, low precipitation, etc.

Ⅱ. The choice of peristaltic pump head

1. The peristaltic pump head chooses single or multi-channel fluid delivery;

2. Whether it is easy to replace the hose;

3. Whether it is easy to fix the hose;

4. The pressure tube gap is fine-tuned by ratchet wheel or other methods to adapt to different wall thickness hoses or to achieve fine-tuning of pressure;

5. Roller selection: the relative flow of the roller structure is slightly larger; the fluid pulsation amplitude of the roller structure is smaller;

6. Whether the trigger structure of the peristaltic pump head is dexterous and whether it is convenient to open the card.

Ⅲ. The choice of peristaltic pump driver

1. Whether flow control is required;

2. Whether liquid distribution is needed;

3. How is the flow range of the peristaltic pump driver;

4. Whether the overall structure is reasonable and whether the operation is convenient;

5. Whether the flow accuracy and liquid volume accuracy of the peristaltic pump driver meet the requirements;

6. Special requirements: protection level, explosion-proof level;

7. External control requirements: equipment matching, operation methods, etc.
