After the strong self-priming pump on site finishes pumping water, the water in the pump will be pumped up. However, if the pump is stopped for a few hours or overnight, the next time the pump is turned on, water must be added to the pump. This is mostly because the water in the strong self-priming pump will be sucked up, while the water in the pump will not be sucked in. This is because after the self-priming pump sucks in water in the pump, the water in the pump will be sucked up, while the strong self-priming pump will suck in water. Then, after stopping the pump for a few hours or overnight, the next time the pump is turned on, water must be added to the pump, which will discharge the water in the pump. In one case, after the next pumping of water, the self-priming pump will be sucked into the water. In this case, after the next pumping of water, the self-priming pump will be sucked into the water, and then the pump will be stopped for a few hours or overnight, The next time the pump is turned on, water will be added to the pump. In this case, after the next pump draws in water, the water will be sucked up. In this case, after the next pump draws in water, the water in the pump will start to be sucked in, and then the pump will draw in water again. In this case, after the next row of pumps draws in water, the pump will draw in water.

The appearance of a strong self-priming pump with a self-priming height of 6-7 meters is the same as that of a general self-priming pump. We only change some shapes and dimensions inside the pump body. The self-priming pump with a self-priming height of 8-9.2 meters adds a vacuum assist system on the basis of the self-priming pump. If a vacuum assist device is added to the self-priming pump with a self-priming height of 9.2 meters, and a vacuum assist device is added to the self-priming pump with a self-priming height of 9.2 meters, the self-priming height of such a self-priming pump is 9.2 meters.
