The top five things that cause inverter failure

 
Feature
 

Dry running leads to a surge in pressure, flow or overheating that will instigate a pump failure. As a result, the pumping elements seize up on the shaft.

 
Feature
 

Five pumps from Termomeccanica were chosen to handle the cooling process in a nuclear power plant.
