How to choose a dosing metering pump for hydrochloric acid correctly www.sucmc.com

Thread Content

To use a dosing metering pump for transporting hydrochloric acid, it is necessary to understand the properties of hydrochloric acid in order to determine how to select the appropriate dosing metering pump. Hydrochloric acid is a somewhat corrosive medium; therefore, plunger metering pumps should not be used – diaphragm metering pumps are the appropriate choice. The specific model to select depends on various parameters. After selecting the appropriate model, a suitable pump head must be chosen based on the properties of hydrochloric acid. The material used for the pump head is usually PVC; for higher requirements, a PTFE-lined pump head is used, as hydrochloric acid corrodes stainless steel, and therefore stainless steel pump heads cannot be used. If some customers require a stainless steel pump head, then it must have a PTFE lining in order to provide corrosion resistance.
