Fermentation tanks are widely used in laboratories, industrial production and other environments. These devices play an important role in biological fermentation. Fermentation tanks need to continuously add and supplement various trace elements or catalysts to control the characteristics of the fermentation liquid, and accurately control the fermentation process through these liquid material supplements.The accuracy of the added trace elements greatly affects the progress of the fermentation process and the quality of the final product.

Usually, various pumps are used in fermentation tanks to automatically and continuously add liquid. The more common type of pump is the peristaltic pump. Its delivery accuracy and long-term reliable operation determine the stability and reliability of the output liquid, so it also plays a particularly important role in the fermentation process.Therefore, special attention needs to be paid to the selection of peristaltic pumps and the matching of models.In the process of choosing a peristaltic pump for the fermentation tank, the following issues should be paid attention to：

1. The matching and compatibility of the type of liquid transported with the pump tube;

2. Pay attention to the corrosion and influence of the materials of the pump head and housing, organic solvents and acids and bases in the industrial environment on the housing and materials of the peristaltic pump.;

3. The rationality and quality of the design of the peristaltic pump itself;

4. The flow rate of the peristaltic pump matches the flow rate required by the fermentation tank.Under the premise of meeting the flow rate, try to choose a low-speed pump to improve the service life of the pump tube and pump.
