Hi all
i'm very confused about centrifugal electric motor driven pump!
what happened to pump amperage, when discharging valve closed 50% and less 10%?
thanks

For exact relationship, you need pump curver and motor characteristics.

My experience, though, has never revealed a centrigugal pump that did not behave that way. Limited to HVAC chilled water and hot water pumps, though. They all have very similar characteristics.
I should have elaborated, but my phone was ringing!
