Safety is a chief concern for all industries. Certain industrial companies in specific markets (Ex. oil & gas, mining, etc.) have regulations related to combustibility due to gases produced or that are existing with applications. In these cases, submersible pumps specially constructed to eliminate the risk of explosions are necessary. In fact, many local jurisdictions explicitly mandate the use of explosion proof pumps.Higher Risk Applications
Certain applications are especially susceptible to explosion risks. The mining and oil & gas industries face pressurized, escaping underground gas. In chemical plants and refineries, liquids emit flammable vapors. Landfill leachate applications include methane from decomposing waste. Also, power plants and industrial plants may have volatile chemicals present. In these cases, a spark from a pump or even a hot enough surface can ignite the gases or chemicals.
