I would like to ask the experts: for transporting benzene and alcohols in truck-mounted tanks, is it better to use magnetic pumps or shielded pumps (30–50 KW)?

Where in China are there applications that are well-developed? Please give me some advice!
It’s better to use a magnetic pump. Magnetic pump is durable ； The price is low.
The conditions are more or less stable when they are stable, but uncomfortable when they are not
Use magnetism. 18032233998 is the same WeChat ID
Either one is acceptable. Magnetic pumps are relatively inexpensive, have low costs for spare parts and repairs, and are convenient to use. However, it is highly recommended to: 1) not install an inverter, and 2) add a buffer tank at the pump inlet, making it as large as possible, to prevent damage to the thrust disc and bearings when the pump runs dry. 3. It is recommended to add fluid back during export; open the supplementary buffer tank when evacuating. 4. Remember that it is not possible to start and stop the pumps frequently, as uneven changes in axial force occur during such starts and stops, which represents the most stressful period for the bearings and thrust discs. Try to keep the pumps running as much as possible – keep these 4 points in mind. Otherwise, you’ll be the ones to suffer.
It’s obvious at a glance that someone has been tortured by these two types of pumps
Price speaks for itself; shielded pumps are more reliable than magnetic pumps.
Pumps are generally selected based on the NFPA value; for high NFPA values, shielded pumps are chosen, while magnetic pumps are used otherwise. For magnetic drive pumps, it is important to be aware of the risk of dry operation; pumps that can withstand dry operation should be chosen.
