Is there anybody know how much we can trim the diameter of impeller in percentage(Any limit to the original size)? And can we bring the affinity law to calculate the pump characteristic curve at reduce impeller size? Please suggust!





RE: Pump impeller
If you are allowed to trim the impeller ,you can calculate the characteristic curve according to affinity law

The information you want is in the hands of the pump manufacturer, they can tell you what the minimum practical diameter is and what diameter to use for any specific duty, otherwise you have no accurate way of predicting other than using the affinity laws.
