Pumps are indispensable fluid transfer devices in both industrial and civilian fields, with their performance and reliability depending on a multitude of meticulously designed components. 

For instance, the impeller, as the core component of a pump, is responsible for converting mechanical energy into fluid kinetic energy; 

while the pump casing protects internal components and guides fluid flow. Seals ensure that the pump can prevent leaks during operation, 

maintaining efficient operation, with common types being mechanical seals and packing seals.
