Key Advantages
1. ATEX Certified, Intrinsically Safe
Designed in strict accordance with ATEX explosion-proof standards, the pump generates no sparks from mechanical friction. It completely eliminates fire and explosion risks during the delivery of flammable and explosive media, and is applicable to all types of hazardous work areas.
2. Sealless & Zero-leakage Design to Prevent Medium Escape
Adopting mature sealless magnetic drive structure, it achieves zero dripping during operation. It effectively stops volatile hazardous chemicals from leaking out, meeting both on-site safety and environmental protection requirements.
3. High Corrosion Resistance for Diverse Chemical Media
The wetted parts of this explosive chemical magnetic pump are made of high-performance anti-corrosion materials. It steadily conveys corrosive, flammable and explosive media such as strong acids, strong alkalis and organic solvents for long periods, and resists erosion and damage.
4. Sturdy Explosion-proof Body with Strong Environmental Adaptability
Featuring an integrally reinforced frame and professional explosion-proof structure, this HX402 magnetic pump for hazardous areas boasts excellent vibration and impact resistance. It runs continuously and stably under high temperature and complex high-risk working conditions.
5. Low Failure Rate & Maintenance-free to Cut Operational Costs
The simple and reliable drive structure ensures low noise and minor wear during operation. Frequent inspection and seal replacement are not required, which greatly reduces manual maintenance frequency and safety risks in hazardous areas.
Typical Applications
● Closed conveying of hazardous chemical solvents in petrochemical industry
As an ATEX magnetic drive pump, the HX402 generates no mechanical friction sparks. It safely transfers volatile flammable solvents such as benzene and methanol, and eliminates explosion risks caused by static sparks.
● Medium transfer in negative-pressure workshops for fine chemicals
Adopting a sealless zero-leakage magnetic drive structure, it adapts to negative-pressure explosion-proof workshops, prevents leakage of volatile corrosive media, and complies with both exhaust emission control and explosion-proof requirements.
● Conveyance of sulfur-containing corrosive wastewater at oil and gas stations
Equipped with high-performance corrosion-resistant wetted parts and a reinforced explosion-proof housing, it resists hydrogen sulfide corrosion in open-air high-risk oil and gas sites, meeting multi-dimensional demands including explosion prevention, weather resistance and impact resistance.

FAQ
Q: Will air backflow occur to the equipment under negative-pressure workshop conditions?
A: No. The HX402 adopts fully sealed seamless welding for its explosion-proof housing and features a closed magnetic coupling cavity inside. Equipped with standard negative-pressure sealing flanges at inlet and outlet, it can completely block external air backflow. No medium oxidation, impeller cavitation or pump idling faults will occur even after long-term start-stop operation in negative-pressure explosion-proof fine chemical workshops.
Q: Will sulfur-containing wastewater cause demagnetization of internal magnetic components inside the pump?
A: It will not under standard compliant operation. As a magnetic pump dedicated for hazardous areas, the HX402 has fully coated anti-corrosion isolation structures for internal magnetic components. Sulfur-containing wastewater only contacts fluoroplastic wetted parts and isolation sleeves without touching permanent magnets directly, which isolates electrochemical corrosion induced by hydrogen sulfide. The magnetic components will not suffer corrosion, demagnetization or magnetic attenuation as long as the isolation sleeve remains intact and the pump avoids dry running.
