Circulator problem

I am at work and I started to hear a grinding noise in the building. I traced it back to the boiler room and one of the circulators was making the noise. (One of those big red ones) I tried adding oil but it didn’t help. I took a closer look and I noticed that the “spinning part” was a bit out of whack and medal shavings were around it. There is a wall switch for each circ., 6 in all. So I turned it off. The system seemed to be running fine after I shut it down. It probably won’t be fixed for a couple of days. Is there anything else I need to do? The system has 2 oil burners linked together and 6 circulators. The other 5 seem to be working fine.
Thanks

Replace the motor mounts on that big red one also.

Spirolink couplings work well.

Circulator repair.

John, you say its one of those big red ones.? Can you get the number off it? If its a series 100, (it sounds like it is from your post) it needs a coupler and new mounts. There are a bunch of aftermarket replacement parts out there but I prefer genuine B&G parts. Again, if its a 100 series, you need coupler B&G 118705+ and Ring motor mount w/screws: B&G 118223.

if it's a Bell and Gossette 100...

do yourself a favor, and replace it with a taco 007, you can get one the HOME-DEsPOT or sLOWES for $65 – cause, a b&g 100, needs 12drops of oil at each end of the motor, and a full ounce of oil, in the center section with the little spring hinged oil fill cap, - each and every year - whereas a taco 007, is silent and don’t need a "thang", - not to mention that it draws less than 100W,

the big red pump is a piece of history, i only use the series 100 for a condensate loop off a steam system, and then only in bronze – the three-piece: because of the superb starting torque, bronze: so that the boilers iron oxide sludge doesn’t stick to it

even b&g makes a water cooled and lubricated NRF-22 that competes with the 007 – so unless you have cast-iron pipes and radiation – I would change them all out for water cooled/lubricated pumps

It is a 100, I am told it was fixed today. I'm not sure what they replaced it with. I just wanted to make sure nothing was going to blow up by shutting it down.
Thanks for the posts.

Series 100

I agree wet rotor pumps are more versatile, however if your pump reqiurements allow for a flat pump curve IMHO B@G pumps are a workhorse. I doubt well be seeing wet rotor pumps with the same life expectancy of three piece pumps. I agree with one of the previous posts A coupler @ motor mounts should do it.
