For benzene compounds, what kind of pump is suitable for transportation?
Generally, a magnetic pump or a shielded pump can be used
Yes, use a leak-free pump – safety first
Given that benzene is toxic and flammable, it is best to use pumps that do not leak, such as magnetic pumps made of stainless steel or polytetrafluoroethylene. A canned pump can also be chosen. We have also used ISW series pumps with carbon steel mechanical seals, and the results were good as well. Pay attention to safe flow rates, static electricity grounding, and flange bonding.
It is best to use a shielded pump; when opting for a conventional centrifugal pump, one must consider the risk of leakage of toxic and harmful substances, as the selection and handling of seals become quite complex in such cases.
In addition to shielded pumps and magnetic pumps, diaphragm pumps can also be used, depending on the flow rate and pressure requirements.
Solvents such as xylene, acetone, and fats are often handled using pneumatic diaphragm pumps. Our company uses Wilton-brand pumps; they are of excellent quality, though they are a bit expensive
Our unit uses magnetic pumps and shielded pumps; personally, I think magnetic pumps are better.
Magnetic drive pumps and shielded pumps are excellent choices; ordinary centrifugal pumps can also be used, but it is necessary to equip them with a PLAN52 or PLAN53 sealing system for reliability. The characteristic of ordinary centrifugal pumps is that both flow rate and head can be made very high.
Fluoroplastic magnetic pumps can be used; they offer an excellent cost-performance ratio!
Because in the event of operation without liquid, the isolation sleeve of fluoroplastic magnetic pumps or engineering plastic magnetic pumps can easily burn out or be punctured. When metal magnetic pumps are an option, it is recommended to use stainless steel magnetic pumps or other types of metal magnetic pumps. When making such recommendations, it is important to consider things from the customer’s perspective
Shielded pumps are more commonly used in industry.
Choosing a magnetic pump or a shielded pump is the best option. In terms of material, stainless steel is the recommended choice; aside from the issues mentioned above, such as damage due to high temperatures, as well as the unsuitability of PTFE and engineering plastics due to their tendency to generate static electricity.
