Tech. Information for the CQ and CQB Magnetic Driving Pump

WORKING PRINCIPLE                                                                                                                                

   

   The CQ and CQB series pump is a kind of magnetically coupled pumps, or magnetic drive pumps, vary from the traditional pumping style, as the motor is coupled to the pump by magnetic means rather than by a direct mechanical shaft. The pump works via a drive magnet, 'driving' the pump rotor, which is magnetically coupled to the primary shaft driven by the motor. The magnetic drving centrigual pumps are often used where leakage of the fluid pumped poses a great risk (e.g., aggressive fluid in the chemical or nuclear industry, or electric shock garden fountains). They have no direct connection between the motor shaft and the impeller, so no gland is needed. There is no risk of leakage, unless the casing is broken.
   The power from the motor is transmitted to the centrifugal impeller by means of a magnetic coupling. A so called isolation shell between the drive magnet and the impeller magnet separate the liquid side from the drive.
   1) Drive magnet, connected to the motor
   2) Isolation shell (rear housing) separating the liquid side from the atmosphere
   3) Impeller magnet assembly, driven by the drive magnet.
