Pump and Valve Component Types: Analysis of Structure and Key Selection Considerations

In the field of industrial fluid control, pumps and valves play a pivotal role, and their performance largely depends on the types of components used. Different types of components are designed for specific working conditions and medium properties, ensuring the reliable operation of the equipment.

From the perspective of structural functionality, pump and valve components are diverse and each has its unique characteristics. In the valve sector, the precise matching of the valve disc and valve seat forms the core of valve sealing, with their material and surface treatment directly impacting sealing effectiveness and service life. Internally in pumps, the impeller, as the key component for energy conversion, determines the pump’s flow rate, head, and efficiency through its shape, material, and machining precision. The pump casing, on the other hand, bears the critical responsibilities of supporting the impeller, guiding the fluid, and withstanding pressure, requiring a structural design that balances strength and flow path optimization.

During the selection process, comprehensive consideration must be given to factors such as medium properties (e.g., corrosiveness, viscosity, temperature), working pressure range, flow requirements, and system compatibility. For corrosive media, priority should be given to materials with strong corrosion resistance, such as stainless steel or Hastelloy, to prevent component corrosion, which could compromise equipment lifespan and fluid purity. In high-temperature operating conditions, components must exhibit excellent heat resistance and thermal stability to avoid deformation or failure due to elevated temperatures. Simultaneously, working pressure is another critical consideration, as high-pressure environments demand components with sufficient strength and toughness to ensure safe operation.
