CQB-G Series high temperature magnetic pump uses multiple circulating cooling structure to ensure the dependability and stability of prime mover and magnetic drive. Meanwhile,pin coupling is used to reduce the noise and vibration of pump. The detachable type and pin coupling makes the structure of pump longer,which is good for heat dissipation. Moreover, to make repair and replacement of spare parts much easier, a heat dissipation fan blade is designed on the outer rotor of pump to ensure the stability of magnet  steel. This  series of pumps are applicable for high temperature mediums,with service temperature is not higher than 300 degree celsius.
