Slurry pumps can be used to pump river water for agricultural irrigation. If the river is clean water, it can be pumped with a clean pump. For example, severe drought occurred in southeast China in the first half of this year. We will use slurry pumps to transport water, which will play a more prominent role in river dredging. China is rich in water resources, there are many sand-bearing rivers, we can use slurry pump to remove the sediment in the middle of the river, dredge the river.
