CQ series magnetic drive centrifugal pump can be widely employed in chemical, petroleum, food, electroplating, pharmaceutical and smelting to pump acid, alkali, oil, rare liquids, and volatile liquids. It adopts magnetic drive to replace the dynamic seal with precision seal, which makes the pump chamber in a completely sealed state, thus completely solving the problems of running, bubbling, dripping and leaking which cannot be avoided by mechanical seal pumps.
