cut down (on a lathe) Explanation: From the context given here, it seems like the diameter should be made smaller. Cut down (on a lathe) the impeller diameter to increase the No Load RPM. http://energyindependence-rob.blogspot.com/2010/02/pumps-as-... -------------------------------------------------- Note added at 32 mins (2020-12-03 16:34:48 GMT) -------------------------------------------------- trim/trimming could also work https://www.ksb.com/centrifugal-pump-lexicon/impeller-trimmi... Impeller trimming refers to the reduction of the impeller diameter, and thus a reduction of the circumferential speed at the impeller outlet of a centrifugal pump. This is done to match the operating point to specifications. |
