This series of pumps is designed for extracting gases from flammable and explosive hazardous locations with explosion-proof ratings of IIA and IIB, and temperature classes of T1-T4. They are widely used in petroleum, chemical, military, explosives, medical, pharmaceutical, scientific research, mining, oil depots, liquefied gas stations, gas pipelines, aerospace, laboratories, and other related fields.
① This explosion-proof rotary vane vacuum pump is specifically designed for high-risk environments. Its core features a composite explosion-proof structure combining flameproof, encapsulation, and intrinsic safety technologies, complying with the high-level ExdIIBT4 explosion-proof certification. This eliminates ignition risks at the source, ensuring inherent operational safety;
② Adopting a two-stage series structure, the gas discharged by the first stage pump is further compressed by the second stage pump, effectively overcoming the limitations of single-stage pumps and achieving higher and more stable vacuum levels, while maintaining a more efficient pumping rate throughout the entire pumping process;
③ The dual-stage structure, combined with a powerful gas ballast valve, allows for the early discharge of small amounts of water vapor during the initial compression stage, preventing condensation and emulsification of the oil. This improves the pump's efficiency and stability in humid environments and extends the service life of the vacuum oil;
④ Its miniaturized design and lightweight body provide excellent adaptability to various locations; coupled with ultra-low noise operation technology, it creates a quiet working environment.
