B&G redfox - corrosion?

This is only 4 years old. Any ideas?

    Find out where the moisture is coming from that's getting on it -- before it ruins the pump.

    A leak above dripping on it? Or water running down one of the wire conduits?

    What is the system material piping like?
  • Here’s a better view of setup - I probably should have mentioned, this feeds a built-in wall heater fan, which operates as its own zone (kitchen).

    That’s the wrong circulating pump for that application, the circulating pump needs to be a 3 piece bronze oil lubricated pump. That is going fail.
    Plus the tapping that’s used as the supply is way to high it needs to be at the return piping or at the boiler drain tapping. Boiler needs to be skimmed too.

    Steam piping appears to be incorrect as well.

    Does anyone see the "steam drier/drum/chamber" on the outlet of the boiler. I am guessing that is what it is. Were they effective?

    Steam separator. Yes, they’re effective. And ditto on the circulator.

  • Thank you all for the quick insight and great help! Will do some further digging and report progress.

    Are we talking the $789 B&G bronze 3 pc pump here? If so, Any alternatives come to mind?
  • I'm not sure how this application would cause the rusting between the electrical box and stator housing. The only things I'm aware of that can cause this are:
    - Moisture following along the electrical wire as Hot Rod says, getting into the electrical box
    - Condensation building up in the stator (between the rotor can and stator housing). This is more typical in chilled water applications where the water temp is lower than ambient causing windings to sweat (obviously not in this situation)
    - A hole in the rotor can

    Clearly this needs to be addressed - if the stator and electrical box flood you will release the magic smoke. Kidding aside, this circ is doomed to eventually fail, either from the excessive moisture in the wrong area or by the misapplication (wet rotor circs do not like the somewhat abnormal TDS and PH typical found in boiler condensate).

    Agree a 3 piece mechanically sealed circ is a better selection (and replacing seals is much cheaper than the complete circ or it's cartridge).

    Replace that style pump every few years is the alternative.
