Just to add to Allan's wonderfully informative post, if you can find a set
of carbon-graphite brushes for any electric motor that is larger in width
and depth (and a proper length) than the ones that you are trying to
replace, you can easily resize them with a sheet of Emory cloth laying on a
flat surface (like a sheet of glass) to make them fit the brush holders in
the pump motor. Just make sure that you take off enough material so that the
new brush slides easily in and out of the brush holder.

 

You can get motor brushes in various sizes from any electric motor repair
shop, or even at auto parts stores. I used to do that all the time when I
was still repairing motors and generators back in the 80's.

 

But as Allan said, it's probably not worth fixing. If it has run through a
set of brushes, it probably has quite a few running hours on it. Who knows
what will wear out next. Better to replace it with a new helical-rotor pump,
like the Grundfos SQFlex, the Mono pumps, or one from Lorentz

Long gone. Years ago, the Italian manufacturer made some products that
weren't up to standard, or some such. Cost Dankoff a lot of money to support
warranties. Dankoff sued the manufacturer in international court and won,
but never collected anything. That was the end of that relationship, of
course. 

Usually the ovoid or the flexible gasket goes before the brushes, and
they're made out of unobtanium. For awhile, Gary Hegg at 

Total Light & Power (505) 772-5759 PO Box 646 Pie Town, NM tried to service
them. I think he eventually gave up, but he might have brushes.

I think I know of one that I installed that's still working after 15 years.
Of course, the property was vacant for 14 of those years. Tip: it's not
worth fixing.

Windy doesn't follow this list any more.

Hope this helps!
Allan

have them? Windy?
