How can industrial peristaltic pumps cope with high temperatures and corrosive liquids?

Many processes in the industrial field require the use of peristaltic pumps, which are highly favored due to their small size, low noise, adjustable flow rate, and the ability to handle various high-temperature and highly corrosive liquids. However, due to the relatively strong characteristics of high-temperature and corrosive liquids, the selection and use of industrial peristaltic pumps need to pay attention to the following points.

1. Choose the appropriate material

When facing corrosive liquids, choosing the material of the pump head can play a crucial role. Some pump head materials cannot meet the conditions of high acidity, high salinity, and high alkalinity, and may be subjected to chemical corrosion; Some pump head materials, although resistant to chemical corrosion, cannot withstand high temperatures. Therefore, choosing pump head materials that are resistant to chemical corrosion, such as PPS, PVDF, PTFE, FEP, etc., can ensure long-term stable operation of the pump. Especially when dealing with liquids with high acidity, high alkalinity, and strong corrosiveness, it is recommended to choose materials that are more corrosion-resistant.

2. Select the appropriate peristaltic pump hose

Hoses are an important component of peristaltic pump performance when handling high-temperature and highly corrosive liquids. When selecting, it is necessary to find hoses that are resistant to chemical corrosion and high temperatures. The use of rigid hoses can reduce the bending of the pipe wall, reduce the heat generated by friction, and improve temperature resistance. Ensuring the quality of the hoses and periodically replacing them is an effective measure to ensure long-term stable operation of the pump. In addition, various suitable hose materials need to be selected according to different process requirements.

3. Reduce traffic and speed appropriately

When dealing with high temperature and corrosive liquids, some corresponding measures can be taken to avoid the heat generated by the hose due to severe friction. For example, appropriately reducing the flow and speed of the pump can effectively reduce the intensity of hose movement and extend the service life of the hose. In addition, regular replacement of hoses and the use of filters during fluid supply can be used to keep the hoses clean, reduce frictional heat, and increase the service life of the pump.

4. Maintenance and upkeep

When using peristaltic pumps, in addition to paying attention to material selection, regular maintenance is also necessary. This includes regular cleaning and maintenance of the pump's operating mechanism to ensure the normal operation of the pump. Regularly check the hoses for wear, aging, softening, and other conditions, and replace them if necessary, which can effectively extend the service life of the peristaltic pump. In addition, when dealing with high-temperature and corrosive liquids, it is recommended to clean and disinfect the pump before and after treatment to ensure no adverse effects on the process flow and maintain the long-term stability of the pump.

In summary, for high-temperature and corrosive liquids, selecting appropriate peristaltic pump materials and hose materials, as well as conducting maintenance work, can ensure long-term stable operation of the peristaltic pump and meet the treatment needs of various high-temperature and highly corrosive liquids.
