great video I learned a lot I've been doing this for 31 years never had any training in this kind of performance testing which working on Chillers real important

I suggest noting the system would need to be sequenced to it's full flow capacity which allows a pump to perform and not be restricted by the system itself. Also important is when a suction reading is negative you would add and not subtract from the discharge side.

I got question for you! I am doing pump curves on new pumps most of the time and actual dead head pressure doesn't match with the given performance curve dead head(curve given by manufacturer)! I checked speed, and impeller size and new pump might not have worn seal or impeller. Is it possible to have air trapped in water system and it will give a wrong reading as air has low density!? its happening a lot! I am really confused and looking for solution to how to find if air in water system? or its something else causing problem! Please help me if you can. Thanks!
