Need rebuild or replacement electric motor

Grundfos or Taco pumps come in a variety of fittings. The may have directly a swappable replacement.

I have a brand new replacement motor for that series circulator that I kept as a spare for our old heating system. I just "found" it when I was looking for something else last weekend.

I am betting that a real plumbing/heating supplier will have one. If not post a followup and we can work out something.

Don't you have motor rewind shops in your area? There are several that I deal with here in town and this is not a huge city.

@uncle K:

Why on earth would you have the motors on the circ pumps you have installed now rewound when it would be cheaper by far to find new pumps of the same ratings and do some plumbing work to install new flanges and piping to fit them rather than trying in vein to find a slide-in bolt-on user-serviceable replacement part...

take sample motor to WW Grainger they can likely match a brand new motor for your needs. you need a buddy with a business to buy there, and pay cash..

there used to be local motor rebuild shops around here i believe the last one closed recently.

and do investigate the pump, it might have a bearing failure making it hard to turn, making the lotor overheat.

finally your very old boiler is likely very inefficent, you should price a whole new boilerr set up.

posters here routinely report they pay for themselves sometimes in less that 3 years

Check for a substitution here:

Can't say I know a lot about hw heating systems but I'm inlcined to say replace the entire unit with a new one. Pump and motor.

I have a motor similar to what you describe. It is a Wagner type RB model S1264 K3779 1/6 HP 1725 RPM. It works, and I have pictures of it. I don't see a place for attachments here . I am in New Jersey. Contact me if interested. Rob rjsgthree@ gmail.com

You think after 12 years he's still looking ?
