Introduction

Le Pompe magnétique en acier inoxydable de la série CQ by Changyupump utilizes a permanent magnet coupling principle to replace dynamic seals with a static isolation sleeve. This sealless design ensures all wetted components remain hermetically sealed, effectively eliminating the leakage, seepage, and dripping issues common in traditional alkali pump applications. Constructed from high-quality 304 or 316L stainless steel, these units feature a pump housing manufactured via a precision silica sol pickling process. This advanced engineering provides superior corrosion resistance for aggressive alkaline media, such as sodium hydroxide, while ensuring the conveyed fluids remain pure and free from contamination.

Beyond its performance as an alkali pump, this Pompe magnétique is engineered for diverse operating conditions in the chemical, pharmaceutical, and petroleum sectors. It is highly effective for the safe transfer of volatile organic solvents, toxic reagents, and flammable liquids where zero-leakage is a critical safety requirement. With a compact structure and low noise profile, these pumps are widely integrated into circulating water systems, filtration equipment, and electroplating baths. The 12-pole ferrite magnet assembly and high-strength, graphite-filled bearings ensure stable, reliable operation for media up to 100°C, delivering a robust solution for high-purity and high-risk fluid handling.

By combining magnetic coupling technology with high-standard materials and manufacturing processes, Changyupump ensures that its CQ Series Stainless Steel Magnetic Pumps can operate reliably and stably over the long term, even under the harsh conditions typical of alkali pumping applications.

FAQ

Traditional mechanical seals often fail when handling alkali media like caustic soda due to crystallization. The CQ Series stainless steel magnetic drive pump adopts a sealless design with a static isolation sleeve, ensuring zero leakage, improved safety, and reliable performance in corrosive environments.

For stable operation, the medium viscosity should not exceed 30 × 10⁻⁶ m²/s. The standard stainless steel magnetic pump supports fluid density up to 1200 kg/m³, while customized designs can handle up to 1600 kg/m³ without risking magnetic decoupling.

Magnetic drive pumps are designed for clean liquids. Solid particles may damage internal components such as bearings or the isolation sleeve. It is recommended to install a filter at the inlet. For ferromagnetic particles, a magnetic filter system is required.

Yes. The standard CQ Series operates up to 100°C, while custom high-temperature models (CQG Series) can handle 200°C–250°C. These configurations typically include insulation jackets to protect the magnetic coupling and ensure stable operation under elevated temperatures.

Yes. The sealless magnetic drive design eliminates mechanical seal friction and heat generation. With a fully enclosed static sealing structure, it significantly reduces leakage and ignition risks, making it ideal for transferring flammable, volatile, and explosive media.

Standard installation is horizontal. If vertical installation is required, the motor must be positioned upward to ensure proper lubrication of internal bearings by the conveyed medium. Additionally, the pump should not bear pipeline loads to avoid mechanical stress.
