B&G Series 100 parts

renotahoe

Hello good people. I have a series 100 B&G on a slant fin boiler. I can hear the pump try to turn on but nothing happens and it's like it times out. Keeps trying but no go. So I would like to rebuild it but want to know what parts to get. My pump is black and everything I see for parts is red. So how do I determine the exact part numbers I need? And based on what I said above any suggestions on what I need? Thanks for your help

Here is a picture of a label on the pump

Have you tried contacting the manufacturer to see what parts are available, and do you know what parts are needed?--NBC

No I found the issue tonight and the only store open is the World Wide Web. I do need to take it all apart to see if the motor or the shaft is stuck.

All parts for Series 100 pumps are available. Your bearing assembly is probably locked up? There's a very good chance a small wet rotor pump will suit your application at a fraction of the cost of the replacement bearing assembly. Less experience and knowledge needed to replace a pump than rebuild one too. Win. Win.

Thanks Stephen. Both water connections are pretty corroded so I am hoping to just get parts to get me through winter. Any concerns that my pump is black and the parts are red? And is a bearing assembly universal for all Series 100 pumps?

I use to run into black B&G pumps years ago, As Stephen said your bearing assy. may be stuck, this usually is caused due to no lubrication. You could try to add some oil ( non detergent ) in the port on top of bearing assy. and 2 ports on motor and try to spin the pump coupler. It could be a stuck bearing assy, a coupler that has broke and jammed or defective motor, disconnecting motor from bearing assy. will give you a better idea. If you have never worked on these pumps may need someone who has experience. Bearing assy, is on water side of system. draining system may be required. Parts should be available at local hvac supply house, you will need horsepower on motor as well. By the time you add up parts prices a new pump could be a option

I've seen mostly red 100's but also black and blue for specific boiler manufacturers. Color doesn't matter. Series 100's are 1/12 hp and like RJ said, pump needs to be isolated or system drained for bearing assembly repair or replacement. Draining, filling, and bleeding a system is not complicated but can be very time consuming depending on the system.
For the sake of comparison, you may want to compare numbers on supply house.com. - Series 100 Power Pack or bearing assembly versus a Grundfos UPS15-58FC or Taco 007.

Latest update and possibly gives us more clues. Took the cover off the add oil on the bearing side and it is full of water. So sounds like that is the area to focus on first. Would you agree?

Tinman

Yes. Seal failed and may have (probably did) caused bearing assembly to seize.

Let me clarify. The bearing assembly, at the very least, needs to be replaced. My recommendation - see above.

Please follow the above advice and forget fiddling around with it for hours to 'get you thru the winter'. Drain the system, new isolation valves, new smaller wet rotor circ, refill/purge. Done for many many years to come. And should you need to replace that circ, you have the isolation flanges and it's a quick change.
