What fluid characteristics are important when selecting a pump?

When selecting a pump, understanding fluid characteristics is essential for ensuring efficient operation and compatibility with the materials used in the pump. Specific gravity is crucial as it indicates the weight of the fluid compared to water, impacting the pump's design and power requirements. Chemical analysis is vital for determining how the fluid will interact with the pump materials, especially in processes involving corrosive or hazardous substances. Solids content is important as it affects the type of pump needed; some pumps handle slurries or fluids with suspended solids better than others.

Focusing on these three areas—specific gravity, chemical makeup, and solids content—allows for a comprehensive assessment of how a pump will perform under various conditions, ensuring reliable and safe operation in the intended application. Understanding these characteristics helps engineers and operators choose the right pump type, material, and size to prevent issues such as cavitation, wear, and contamination.
