​In the engineering field, pumps play a crucial role in the transportation of fluids from one place to another. However, their functionality is heavily dependent on several components, one of which is the seal. Seals are fundamental elements within pumps, ensuring not only efficient operation but also safety and environmental compliance. This article delves into the importance of seals in pumps, explaining how they maintain fluid integrity, prevent leaks, and enhance overall system reliability.

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.
