May I ask which document specifies that magnetic pumps or shielded pumps must be used for transfer pumps handling media such as benzene and toluene?

Dear experts: Which document specifies that magnetic pumps or shielded pumps must be used for transfer pumps handling media such as benzene and toluene? Due to maintenance and other reasons, we do not want to use shielded pumps. Is this acceptable?
Volatile and harmful substances to human health such as benzene and toluene are considered hazardous chemicals, and their transportation must comply with relevant safety regulations. China’s Regulations on the Safety Management of Hazardous Chemicals stipulate that for hazardous chemicals such as those that are flammable, explosive, or toxic, safety pumps that meet **standards or industry standards should be used for transportation purposes, in order to ensure safe production. Regarding the selection of pumps for transporting media such as benzene and toluene, in accordance with the standards \"Magnetic Pumps for the Petroleum and Chemical Industries\" GB/T 5659-2017 and \"Chemical Process Pumps\" GB/T 5656-2017, pumps for transporting volatile and toxic media like benzene and toluene must be magnetic pumps or shielded pumps. This is because magnetic drive pumps and shielded pumps can effectively prevent leaks in terms of design and structure, thereby ensuring the safety of the working environment. If you do not want to use a shielded pump, you need to consult the relevant departments and comply with the applicable safety regulations. At the same time, it is necessary to select an appropriate conventional pump based on the properties of the medium in question, to ensure that it can transport the medium properly and safely. .
It’s a safety requirement, right? A leak-free pump must be used. If you don’t want to use a shielded pump, you can choose a magnetic pump.
If the flow rate is too high or the head is too great, a magnetic pump cannot be used. It seems that high temperatures also have an impact on magnetic pumps.
Yes, in these situations, magnetic pumps will have a hard time dealing with them. Then a centrifugal pump with double-end face seals can be chosen
However, the design institute says that for such a medium, leak-free pumps such as shielded pumps or magnetic drive pumps should be used; at present, the design team has not provided me with specific specification requirements.
