Applying Motor Control in a Wastewater Application
Proper pump, motor, and controls selection optimizes the performance of water
treatment systems and can provide energy savings of 20% - 50%. Selecting a pump with
the correct characteristics is achieved by studying pump performance curves. Below is
an example of an ESP (Electric Submersible Pump) pump performance curve.
