Introduction
The HDH400 toxic chemical magnetic pump is specially designed for conveying toxic and hazardous chemical media. Featuring a sealless magnetic drive and fully enclosed structure, it completely eliminates liquid leakage and prevents the escape of toxic liquids and harmful gases, protecting personnel and the surrounding environment.
Its wetted parts are made of premium anti-corrosion materials with outstanding chemical resistance, enabling stable long-term delivery of various toxic chemical raw materials, potions and corrosive hazardous chemicals. As a hazardous chemical transfer pump, it adopts non-contact drive, running smoothly with low vibration. Boasting a robust structure and easy maintenance, it supports prolonged continuous operation. Widely used in fine chemicals, pharmaceuticals, pesticides, electroplating, environmental water treatment and other industries, it is the ideal choice for the sealed and safe transfer of toxic and high-risk chemicals.

Key Advantages
Ultimate Sealing, Zero Leakage of Toxic Media
Adopting a sealless magnetic drive structure with no dynamic sealing points, this pump completely blocks the escape of toxic liquids and harmful gases compared with conventional pumps, providing full protection for personnel and plant environment.
Special Corrosion-Resistant Material for Highly Corrosive Toxic Media
The wetted parts of HDH400 toxic chemical magnetic pump are made of high-grade anti-corrosion base materials. Specially optimized for highly toxic, strong acid, alkali and highly aggressive chemical media, they resist corrosion and penetration during long-term service, making the pump suitable for continuous transfer of high-risk chemicals.
Wear-Free Contact-Free Drive for Long-Term Stable Operation
The non-contact magnetic coupling operates without mechanical friction and wear. Components are less likely to age or damage under toxic working conditions, granting the pump a far longer service life than traditional pumps.
Integrated Explosion-Proof & Leak-Proof Structure for High-Risk Areas
With an all-in-one fully enclosed design and spark-free operation, the pump works safely in complex high-risk chemical zones where toxicity, flammability and explosiveness coexist.
Low-Frequency Maintenance Design to Reduce Operational Risks in Hazardous Zones
Free from vulnerable sealing components, the pump features a simple and robust structure with long maintenance intervals. It reduces personnel access to toxic working areas for inspection and repair, effectively lowering operational safety risks.
Typical Applications
● Toxic pesticide intermediate transfer
Featuring a fully sealed seal-free structure, the HDH400 blocks leakage of toxic liquid droplets and aerosols to prevent occupational poisoning, suitable for closed pesticide synthesis workshops.
● Highly corrosive cyanide-containing electroplating wastewater transfer
Adopting special corrosion-resistant base materials, it resists dual corrosion from cyanides, concentrated acids and alkalis, solving the common failure of penetration and cracking of ordinary magnetic pumps.
● High-activity toxic pharmaceutical raw material transfer
Wear-free non-contact drive avoids cross-contamination of media, and its extended maintenance cycle cuts personnel exposure risks to toxic pharmaceutical raw materials.

FAQ
Q: Will highly corrosive electroplating wastewater damage the pump and shorten its service life?
A: No. The HDH400 adopts double-layer composite special corrosion-resistant wetted parts. The inner layer resists microscopic penetration of cyanide ions, while the outer layer withstands strong corrosion from concentrated acids and alkalis. Besides, the impeller and pump cavity inner wall are coated with hard ceramics to resist erosion caused by metal residues in wastewater. It avoids substrate bulging, penetration cracking and internal abrasion, and maintains the rated service life for long-term electroplating wastewater transfer.
Q: Will friction heat generated during pump operation alter the chemical properties of chemicals?
A: No. The HDH400 adopts contact-free magnetic coupling drive, with no physical contact or mechanical friction between internal components. It generates negligible frictional heat and keeps the medium temperature rise within 3℃. Equipped with reserved heat dissipation flow channels on the pump casing, it dissipates residual heat rapidly. It will not change the pH value and molecular structure of toxic chemicals, electroplating potions and pesticide intermediates, preventing chemical decomposition, failure and polymerization deterioration.
Q: How to reduce cover-opening maintenance time when transferring toxic media?
A: It can be solved by the original cover-free maintenance structure of HDH400. As a toxic chemical magnetic pump, it eliminates all frequently worn vulnerable parts such as shaft seals and gaskets, requiring no regular cover opening for seal replacement. Internal magnetic components undergo anti-corrosion passivation treatment to support 24-month maintenance without opening the pump cover. Besides, the quick-release split pump cover enables fast disassembly without pipeline removal, cutting personnel exposure time in toxic working environments.
