Now with the use of Variable Speed Drives we have found new ways of doing things. Do I still need to trim the impeller? This course will answer that question.
Participants will learn and/or understand:
Reading and Interpreting the pump curve – Explain what the information means
Understanding the effect of trimming an impeller on the pump performance curve
Evaluating and using the pump efficiency curves to make pump decisions
Understanding the effect of trimming the impeller has on pump efficiency and power usage
Evaluating the use of variable speed motors on pump curves and pump efficiency
