California said:Are you sure that applies to this type of pump? (I assume it is a centrifugal pump.) My experience using similar centrifugal pumps on a gold dredge is that when the intake is clogged, it just spins at no-load governed speed same as a clogged vacuum cleaner. I don't see how that would stress it. It's easy to notice the increase from 3000 rpm (full load) to 3600 (governed max) that signals it is time to go clean the strainer.
I would think it's less of a strain on the pump as it is an overheat condition. The pump has to get some kind of cooling from the water coming through it, and if you just keep spinning the same water (no flow) it doesn't have a chance to take the heat away?
