This article will start from the flow, head, power, material and other key parameters, to provide you with a detailed automatic submersible pump selection guide.

1, clear application scenarios and requirements
First of all, before the selection, it is necessary to clarify the specific application scenarios and needs of automatic submersible pumps. Whether used for field irrigation, urban drainage, industrial water treatment or domestic Wells, each scenario has different performance requirements for submersible pumps. For example, farmland irrigation requires large flow, low head submersible pump to meet the wide irrigation area; Urban drainage systems may require submersible pumps with high head and strong discharge capacity to cope with severe weather such as heavy rain.

2. Consideration of flow parameters
Flow rate is one of the key parameters in the selection of automatic submersible pump, which represents the amount of water pumped per unit time. In the selection, the appropriate flow range should be determined according to the actual demand. For scenarios that require a large amount of water supply, such as farmland irrigation and industrial production, submersible pumps with large flow rates should be selected; For domestic Wells or small ponds, small flow submersible pumps are more economical and practical. At the same time, it is also necessary to consider the impact of flow changes on the performance of the submersible pump to ensure that it can run stably under different working conditions.
