1. Considering that the industrial pump is a special pump for filter press, when designing the impeller profile, we adopt a large wrap angle design to make the clean water performance curve of the pump steeper, so that the pressure can rise rapidly and reach the pressure maintaining state in the process of flow quality change from the feeding stage to the pressure maintaining stage, which is more suitable for the working condition request of filter press;
2. When the feed pump of the filter press requests feed, the flow is large, and the design inlet of the pump is large, which ensures the flow request and effectively improves the efficiency of the industrial pump when feeding, reduces the flow rate, so as to reduce the wear of the medium on the pump; and the runner of the impeller is designed as a narrow runner to ensure that the flow rate will not be too large, so as to prevent the motor from burning.
1. The joint of sheath and guard board is thickened, with better wear resistance and longer service life;
2. The impeller type has larger wire wrap angle and narrow flow channel, which is suitable for the working condition of filter press;
3. The large inlet of the slurry pump and the narrow impeller channel not only improve the flow of the industrial pump, reduce wear, but also ensure that the flow will not be too large when feeding, so as to meet the feeding requirements of the filter press and maintain the motor power.
