Pump performance curve
Thread Content
Today, while looking at the pump selection manual (Dalian Deep Blue), I noticed terms such as Φ160 and Φ180 on the performance curves of the pumps. I’m not sure what they mean, so I’m asking for clarification. Thank you in advance!
Performance curves corresponding to different impeller diameters
Φ160 and Φ180 refer to impellers of different diameters
Different impeller diameters result in different performance
I learned more about pumps once again, and now I understand this: different impeller diameters correspond to different performance curves； These numbers are the impeller diameter. Thank you all again for helping me clarify my doubts!
