Trimming Impellers to Reduce Energy Consumption
System design engineers typically “round up” system capacity and losses to leave room for everything from changes during construction and potential facility expansions to fluid viscosity changes and the gradual roughening of pipe surfaces over time. As a result, pumps in the field often run at higher pressures and flowrates than their application requires.
