Noisy boiler pump

[siden]

Hi all

Central heating/hot water pump is milking a real noise on and off...

Any ideas if there's a fix or is it a new pump time? After this noise it sometimes makes a noise like popping in the pipes.

Cheers

Sounds a bit like there's no water in it! Is the heating/hot water actually working? If so then it can't be running dry but it's definitely knackered.

Sounds like the bearings have had it, leading to the impeller contacting the pump body. New pump needed I think and as said, make sure it has water. I've seen Wilo pumps go like this.
