Sweet! Looks great. Well oiled machine! Any updates?

As far as noise is concerned going to a brushless unit is the answer. They are silent.

Changing the bearings in the pump head is straight forward. I suggest a nice Japanese bearing if your supply house has them but they should be available locally.

Changing brushes on a brushed unit is straight forward. I have actually seen replacements at Ace Hardware... You should still be able to order from CP or find the brushes surplus if you want originals.

Taking the motor itself apart is a bit more complex but if it does have bad bearings (still crunchy with brushes and gearing removed) they can be replaced. I have never done so and if I did would probably take it to a specialist for service.

I have an old brushed unit for my ATO pump. The thing sounds like pure hell. Pumps just fine . It could be a good candidate for a rebuild.

Ultimately, you want the AP regulator to run continuously. With this setup there is no need to worry about the ph changing on you randomly. You are supplying a metered amount of water and gas. The ph probe should be there only as a meter and to make adjustment easy. On my setup the controller is set to turn off the reactor should ph drop to 6.3. Since I run my reactor at 6.5 it never turns the regulator off.
