Critical Pump Protection – Cooling Systems/Tower

Pumps are extremely critical devices at Power facilities.  If pumps fail, turbines and other key parts of the power generation plant will be shut down. One common point of failure in pumps is bearing failure.  Most large pumps have bearings that wear out over time and temperature is normally a good way to monitor the pump bearings looking for wear or simply to perform routine maintenance.  While control systems can monitor pumps many times these pumps are remote to the control room.
