Pump selection is a key step to ensure the performance and use effect of the pump. In the selection process, we need to consider a number of factors, including the nature of the liquid, flow requirements, head requirements and installation environment.

First of all, understanding the properties of the liquid is the basis of selection. Different liquids have different requirements for the material and sealing performance of the pump. For example, corrosive liquids need to choose a pump made of corrosion-resistant materials, while high temperature liquids need to choose a pump with good high temperature resistance.

Secondly, flow and head are important parameters for selection. The flow requirement determines the displacement of the pump, and the head requirement determines the working pressure of the pump. In the selection, we need to choose reasonably according to actual needs to ensure that the pump can meet the working requirements.

In addition, the installation environment is also one of the factors that need to be considered when selecting. Different environments have different requirements for the protection level and heat dissipation performance of the pump. For example, the wet environment needs to choose a water pump with good waterproof performance, while the high temperature environment needs to choose a water pump with good heat dissipation performance.
