The impeller can be used 90 years of the best self-balancing axial force hydraulic model, making pump bearings and mechanical seal life greatly extended.

叶轮采用90年代最优秀可自平衡轴向力的水力模型，使得泵轴承和机械密封使用寿命大大延长。

Also in order to maintain the main impeller axial force balance, have to set up a vice-impeller structure, it can reduce the pressure sealed chamber so that the axial force pump and mechanical seal life expectancy are greatly increased.

另外为了保持主叶轮轴向力的平衡，须设置一个副叶轮结构，它能降低密封腔的压力，使电泵的轴向力及机械密封的寿命均大大提高。
