Bomba magnética de aço inoxidável da série CQ para alcalinos
O Bomba magnética de aço inoxidável da série CQ by Changyupump utilizes a permanent magnet coupling to replace dynamic seals with a static isolation sleeve. This sealless design ensures wetted components remain completely sealed, effectively eliminating the leakage and dripping common in traditional alkali pump applications such as sodium hydroxide transfer. Constructed from 304 or 316L aço inoxidável, these units provide essential corrosion resistance while preventing medium contamination.
Beyond its role as an alkali pump, this Bomba magnética de aço inoxidável is engineered for volatile organic solvents, toxic reagents, and flammable liquids. With a flow range of 1.2–60 m³/h, the internal graphite-filled bearings and high-strength shaft ensure stable performance for pharmaceutical and electroplating fluids. The 12-pole ferrite magnet assembly supports reliable operation for media up to 100°C without mechanical contact.

Introdução
O Bomba magnética de aço inoxidável da 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 aço inoxidável, 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 Bomba magnética 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.
