The impeller blade geometry—including diameter, pitch, number of blades, and blade thickness—directly influences both hydraulic performance and mechanical strength. For multiple impellers on a single shaft, each impeller must be mechanically capable of withstanding its proportional share of the total power while also meeting process requirements.
