Airports are one of the places most crowded with ordinary people and staff, internal and external, permanently exposed to countless risks; among many, some areas of the airport are characterized by a high risk of explosion, a risk that could lead to hundreds of victims, as well as irreversible environmental damage. To ensure the functionality in complete safety of all airport sectors, we at Officine di Trevi have developed submersible pumps, ATEX certified and not based on the site, to be installed in tanks for the transfer of hydrocarbons, control wells for kerosene pipes and wells unloading generally present within the territory of an airport. All the electric pumps are equipped with accessories and cables suitable for permanent immersion in the aforementioned liquids, which can be more or less charged.
