Topic: Re: Why is our pump operating at a lower pressure and drawing higher amps?

posed by 
When a pump operates at a lower pressure and draws higher amps, it usually means it's running further out on the curve. If this continues to a higher flow, then the motor will naturally trip out if size does not cover the run out condition of the pump. It is possible that the new impellers are larger or different hydraulic than the older ones. Unfortunately, you don't provide enough information to be absolutely certain.
