Bell & Gossett circulator leaking

Alan (California Radiant) Forbes

These pictures are of a circulator in a residential system with radiant tubing in the ceiling. There is a steady drip coming out of a hole at the bottom of the bearing assembly. I'm thinking there's a leak in the seal where the impeller shaft goes through the bearing assembly. Does anyone have any experience with this?

This is a HV (high volume) circulator and it's double the size of a series 100 pump.

Yup. That's a leaking bearing assembly.

I tried to buy only the bearing assembly at a supply house once, they only sold whole pump.

Problem is you don't know if shaft is scored also. On cars you usually don't see damage to only one surface.

That's a mechanical-seal leak. Have you tried supplyhouse.com?

I think CalHydro is the rep out there,I'll bet they have a seal kit on the shelf at a supplier near you?

They are my go-to supplier for B & G and got a price for a replacement circulator. I didn't even ask for a seal kit; I no longer have the temperament.

And as Leonard said, "Problem is you don't know if shaft is scored also. ".
