What to do if the pressure maintenance pump for fire protection operates at high temperatures for extended periods?
Thread Content
I would like to ask the experts: If a fire pressure maintenance pump runs for a long time without any leaks in the pipelines, and the water temperature inside those pipelines is very high, what should be done?
Check whether there is a fault in the control circuit?
Increase the reflux slightly, as long as the pump outlet pressure is maintained.
How high is the temperature? It is designed that way; it can operate for long periods of time without any problems.
