In the petroleum and petrochemical industry, crude oil, refined oil products, and various chemicals are highly volatile, mixing with air to form explosive gas atmospheres. The occurrence of an accident requires the simultaneous presence of three conditions: combustible material, oxidizer (oxygen), and an ignition source. Various motors operating on-site, during normal operation or in fault conditions, may generate electrical sparks or overheated surfaces, precisely constituting a dangerous ignition source.

Rotary lobe pumps are widely used in this field for the transfer of oil products and chemical media. If their accompanying motors lack explosion-proof characteristics, internal arcing or surface high temperatures that may leak out could easily ignite the surrounding environment, triggering catastrophic explosions. Therefore, pump selection must never consider only flow rate and pressure; the explosion-proof performance of the driving motor is the primary safety threshold.

The industry strictly classifies hazardous area levels (such as Zone 0, Zone 1, Zone 2) based on the probability and duration of occurrence of explosive atmospheres. In typical Zone 1 locations where oil and gas accumulate, such as pump areas and loading/unloading platforms, high-level explosion-proof motors like flameproof type (Exd) must be used. Their design ensures that any internal explosion does not ignite the external environment, achieving intrinsic safety. If rotary lobe pumps are installed in such areas, equipping them with compliant explosion-proof motors is a mandatory standard; there is no room for choice.

The expansion of modern industrial scenarios, such as edible oil extraction workshops using hexane solvent, and fuel service stations widespread in urban and rural areas, has further broadened the application scope of explosion-proof motors. The potential explosion risks in these locations necessitate that related fluid transfer equipment must take explosion-proofing as a design prerequisite.

Choosing a lobe pump equipped with an explosion-proof motor is by no means merely a passive response to regulations, but an active approach to risk management and safety assurance. It fundamentally severs the "ignition source", minimizing the possibility of accidents. Furthermore, modern explosion-proof motor technology can already effectively balance energy efficiency optimization, achieving a unity of safety and economy.

In the petroleum and petrochemical field, rotary lobe pumps must be equipped with explosion-proof motors. This is an inevitable requirement based on the scientific understanding of explosion risks, a fundamental safeguard for protecting life and property safety, and one of the most basic yet critical links in the industry's safety production system.
