This week I answer a question about trimming impellers on pumps that have VFD's. After reading a little bit I think I have a good response thanks to Norm Hall over at RL Deppmann. It is a rather short episode so listen and share it.  Show notes as per usual can be found over at www.hvac360.com/138 . Enjoy!<hr><p style='color:grey; font-size:0.75em;'> Hosted on Acast.
