Had a close call last week with a 20-year-old boiler feed pump
I used to just check the casing for cracks, but now I always pull the impeller and check the shaft keyway for wear. A guy in my old shop said he saw one shear and wreck the whole pump housing. How often do you all do a full tear-down on your feed pumps?

Isn't that always how it goes, the little things you ignore eventually become the big expensive problem?

My buddy learned that lesson the hard way. His feed pump sounded fine for months, just a tiny vibration. He kept putting off the full check. Then the key sheared, the impeller went off center, and it chewed up the casing and the shaft. Cost them a fortune in downtime and parts. Now he does a full tear down every other year, no matter what. Says it's cheaper than the alternative.
