Squeaking pump

[poshman]

Hi helpers been a few years since I’ve been on the site for help !
Anyway I have an annoying squeaky grundfos circulating pump. I have given it a tap, unscrewed the big screw for air locks I’ve even flushed out a few gallons of dirty water from rads it doesn’t squeak all the time which is strange but it was this morning even with the hot water on
Any advice appreciated PM

New pump required....sounds like the bearings are worn.
