submersible pump impeller noisy

[Usman]

hi, i hear little rattling sound from pump which is not continuous (like frog trrr .... trrr ) since last week , i took it out cleaned it and it increased lol i think the algae was working as grease , i did notice my steel rod shaft is having some scratches i dono if its normal after year.

my question is , is there any remedy to make it stable i think its wobbling thats making noise , can i apply vaseline or silicon , thread etc to make it more stable and avoid friction for the time being ?

has any one replaced the shaft is it easily available in all sizes? i cant contact the exact manufacturer but can search in market for replacement

The little bushings that the shaft rotates in may be worn out, so you may need to replace the whole impeller assembly.
Depends on which brand pump you have.

In agreement with @MitchM , time to replace the impeller assembly.

Yep as stated above. The only thing I would add would be to let it go until it dies, Unless its a very expensive pump it isn't worth trying to fix it. The shaft could be worn, the seals could be worn and the bearings could be worn.

I had a piece of grit got in my old pump behind the impeller shaft and made a noise .

Same here, but with tiny bits of gravel.
