CQB-G型高温保温泵采用多重循环冷却结构，保证了原动力和磁传动的可靠性和稳定性，同时采用柱销联轴器减少了泵的噪音和震动，便拆式和柱销联轴器同时使用，使泵的结构增长，更有利于泵的散热。同时，也十分方便用户的维修或更换零件，在泵的外转子部分还设计了散热风叶，确保磁钢的稳定性。本系列泵适用于输送高温介质，温度≤300℃。

CQB-G 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 outerrotor of pump to ensure the stability of magnet steel. This seriesof pumps are applicable for high temperature mediums, withservice temperature≤300℃.
