CQ series self priming magnetic pumps are characterized by reasonable design, advanced technology, full seal, no leakage, corrosion resistance and so on. Generally, it can be used for such media as acid, alkali, oil, rare and precious liquid, toxic and volatile substances, and it can be widely used in petroleum, chemical, pharmaceutical, electroplating, environmental protection, water treatment, national defense and other industries. At the same time, the pump's filtering parts are in a completely sealed state, completely solving the problem of leakage that can not be avoided by mechanical sealing of other pumps.
