Would you upgrade from Reeflo Baldor Hammerhead?

You already have time invested may as well use some sand cloth on it and rebuild it. It is worth a try. You could use a digital micrometer to check diameter if you wanted to get technical.
They are good pumps just too noisy for a living area in my opinion. I used to run a hammerhead 20 years ago…. Good pump but loud.
My RD closed loop pump went out recently after only a couple years. Total disappointment for what it costed. No replacement parts for a $1500 pump. I installed a varios10 with VCA nozzles and the flow is amazing. Also it is silent and has a good warranty. So far so good.

Agreed they are loud. Mine is remoted to the basement so that helps.

But it sits on a plywood structure that supports the sump, and that structure is screwed into studs that support a wall. The vibration transmits and you can feel/hear it upstairs. If I were to redo the installation I would pay more attention to isolating the pump platform so that it was not in contact with anything that might be able to transmit vibration through the house.

Well, cleaned it up. But then I figured out the shaft itself has very little to do with the seal, so a little pitting or corrosion shouldn't make a difference.

Motor is rebuilt at this point. Need to run out for some silicon and the pump is next.

Used a gear puller to get the old bearings off the shaft. Easy. Put the shaft and core in the freezer and new bearings in the oven at 225°F. Flipped the rear housing over and slid it over the shaft onto the new bearing to get an even surface for hammering, then used a spark plug wrench to get the front seal all the way onto the shaft. The rear seal dropped right in place.

This type of vibration noise would happen with any pump. Not unique to this pump... or the style of pump.

This is why folks tend to use soft vinyl tubing to connect the pump to the plumbing and use foam pads under their pumps, etc.

Some better manufacturers even package their pumps with a pad to put under it, taking the guesswork out of it.

You could probably add some of these (or similar) strategically between your wall and your pump platform (maybe under the pump) to correct your situation:

Thanks for the isolation mount idea. Maybe next build.

If I were to do this one over, The platform holding the pump would be free-standing and not attached at all to any stud wall. As it is now, that platform supports the pump and the sump, and is screwed into the studs. I would need to shut the system down, drain the sump, then rebuild it all free-standing. Way too much effort and risk for the benefit at this point.
