placing electric pump unit in hazardous location
(OP)
Our engineers are planning to put a portable electric pump unit to remove residual ethanol in the tank. Distance of the tank outlet to the pump unit is only 1 meter over it. The pump unit and the electric motor is a pump used for hazardous locations. As a safety officer, I do not allow it because of the placement of the pump is within the dike that protects the tank from possible spills of ethanol. Although the use of the pump is only used for 6 hours. I mean, is there a standard that allows the placement of the pump in the dike that contains two tanks with a capacity of ethanol 5000kl? thank you very much

Pumps are not placed in dikes because they don't work well under water (rain water or whatever other liquid the dike may fill with). Flashpoint is not the same as auto-ignition temperature. You should study both these terms so you understand them.

In sum, there is not a standard that prohibits putting a properly-rated temporary pump in there (it could even be installed inside the tank if needed). There is a standard which specifically permits it, though.
Compositepro gave you the best idea of all -- an air-driven diaphragm pump. No electcity in the hazardous area.

Use bonding/grounding (when you say portable, it echos flex hose).
