Problems with removing the rotor of a coaxial pump
Thread Content
The shaft diameter of a co-axial pump has worn down and become too small, requiring replacement. After removing the rotor, there is still the rotor part from the motor attached to the shaft; can this part be removed so that only a bare shaft remains?

Can this rotor be disassembled any further? Remove the optical axis
Send photos from the site to further finalize the plan.
Can a metal repair agent achieve such significant results? ? ?
It depends; if the wear is too severe, it’s also possible to grind it down and then fit a sleeve
:I suggest you don’t touch the motor part. It’s not easy to remove the motor rotor, and even if you do manage to remove it, you’ll still need special tools and equipment to press the rotor back in place; definitely, there will be issues with its concentricity after that. If the accompanying impeller is qualified before leaving the factory, it is generally subjected to dynamic and static balancing. Just install it and that’s it
