Regarding the selection of VS3-type axial flow pumps

2021-08-20View Original

Thread Content

Process requirements: density of 1000, flow rate of 10,000, head of 20； Some manufacturers choose relatively large impellers (around 1000) when making their selections, resulting in a relatively lower rotational speed ； Some manufacturers choose an impeller one tier lower (one with a diameter of around 800) but with a higher rotational speed ； The shaft power is basically equivalent ； If all other conditions are the same and the selected motor power is identical, how can these two options be compared? Is it better to choose large wheels for slower speed, or small wheels for faster speed? Please, experts, share your opinions~
