Reasons why the condensate- or boiler-feed pump i

The condensate is too hot for the pump. As steam traps fail, the returning condensate will get hotter. If the condensate gets too hot (say, near 190 degrees F.), the pump might cavitate when it runs. Cavitation is what happens when a centrifugal pump tries to pump water and the water flashes into vapor. It sounds like gravel is moving through
