Explosion protection for liquid oxygen pump motors
Thread Content
Oxygen is not considered a flammable substance. Is it necessary to use explosion-proof electrical equipment in an oxygen-rich environment, and what standards govern this? In foreign countries, explosion-proof motors are generally not used for liquid oxygen pump motors; should such motors also be explosion-proof?

Generally, the motors of imported liquid oxygen pumps are not explosion-proof motors; an IP55 protection rating is sufficient； The electrical equipment used in conjunction with it also does not need to be explosion-proof; only the motor of the LNG pump is an explosion-proof type. The on-site control panel used must, however, be explosion-proof. I guess this is another difference between oxygen and LNG
