If the submersible pump is installed too high, it will have an adverse effect on its water absorption performance, operating efficiency, noise, wear and other aspects. Therefore, when installing a submersible pump, its installation height should be fully considered, and corresponding measures should be taken to ensure its normal operation.

Atmospheric pressure has an important influence on the suction height of self-priming pumps. When selecting, installing and using a self-priming pump, it is necessary to fully consider the local atmospheric pressure and altitude conditions, and take corresponding measures to ensure the normal operation of the pump and the stability of the suction height.

the influence of the physical properties of the medium on the pump mainly includes factors such as viscosity, specific gravity, and temperature. When selecting the pump type and material, it is necessary to select the appropriate pump type and material according to the characteristics of the medium to ensure the normal operation of the pump. At the same time, during the use of the pump, regular maintenance and inspection are also required to extend the service life of the pump.

In modern industry and urban infrastructure, multistage pumps are widely used due to their high efficiency and stable performance. Multistage pumps are composed of multiple single-stage pumps connected in series, and the pump head and flow rate are increased by increasing the number of stages. Therefore, the number of stages of a multistage pump becomes a key factor affecting its performance and application.
