How to choose a suitable chemical pump for different concentrations of hydrochloric acid?
Hydrochloric acid is corrosive, and different concentrations of hydrochloric acid have different requirements for chemical pumps and the materials of the pump body flow parts.
Material selection for chemical pumps
Low-concentration hydrochloric acid (<20%) has a certain degree of corrosiveness, but it is relatively low and is suitable for processing materials resistant to weak acid corrosion, such as PVC, PP, etc.
Medium-concentration hydrochloric acid (20%-37%) is highly corrosive and usually requires the use of more corrosion-resistant materials, such as PVDF, PTFE, etc.
High-concentration hydrochloric acid (37%-40%, concentrated hydrochloric acid) is very corrosive and requires the use of highly corrosive materials, such as PFA, ceramics, etc.
Type selection of chemical pumps
Corrosion-resistant magnetic pump: leak-free design, suitable for conveying corrosive and hazardous media such as hydrochloric acid. Magnetic drive eliminates the shaft seal of traditional pumps and reduces the risk of leakage.
Fluorine-lined magnetic pump: lined with fluoroplastics, with excellent corrosion resistance, suitable for conveying high-concentration hydrochloric acid.
Fluoroplastic magnetic pump: magnetic drive technology, excellent sealing performance, resistant to strong acid corrosion.
Other considerations
1. Operating conditions
Temperature: The hydrochloric acid delivery temperature has an important impact on the material selection, and a pump made of high-temperature resistant materials needs to be selected.
Flow and head: Select the appropriate pump model according to the flow and head requirements of the hydrochloric acid delivery.
Viscosity: Although the viscosity of hydrochloric acid is low, it may change in high concentration and low temperature environments, and the viscosity adaptability of the pump needs to be considered.
2. Safety
Leakage prevention: Hydrochloric acid is highly corrosive and volatile. Selecting a pump with good sealing performance can effectively prevent leakage.
Corrosion resistance: Ensure that all parts of the pump that come into contact with the medium are made of materials that are resistant to hydrochloric acid corrosion.
3. Maintenance and use cost
Easy maintenance: choose pumps that are easy to maintain and service to reduce downtime and maintenance costs.
Service life: choose pump materials and designs with high durability to reduce long-term use costs.
For conveying hydrochloric acid of different concentrations, it is recommended to use a fluorine-lined magnetic pump or a high-performance plastic pump. Select the appropriate material and pump type according to the specific concentration of hydrochloric acid and operating conditions to ensure the safety and reliability of the conveying process. At the same time, consider the maintenance and use costs of the pump and choose a pump product with a high cost performance.
