Description for Bell & Gossett 106189

The closed-loop Bell & Gossett Series 100 Inline Circulator Pump is designed for use in domestic and light commercial water circulating systems, such as hydronic heating and low-pressure boosting. The motor on this pump is oil-lubricated which, along with the three-piece design, provides for easy field service. The shaft and seal are housed in an assembly that can be easily repaired or replaced. This pump's motor design, coupled with its overall hydraulic performance, allows the Bell & Gossett Series 100 to overcome system-related noise caused by valves, fittings, or piping. And resilient mounting provides quiet, dependable service with minimum annual lubrication.

The Bell & Gossett 106189 features a precision ground pump shaft is oversized to provide large bearing surfaces and a hardened integral thrust collar minimizes end-thrust to ensure long seal and bearing life. The mechanical seal is designed to withstand the wide range of water temperatures, pressures, additives and dissolved solids common in hydronic systems.

Comes with gaskets, bolts, and oil. Not for use in potable water systems. This pump may also be referred to by the Bell & Gossett model number 100NFI. UL, CSA listed.

Installed pump several weeks ago an it's running smoothly and keeping my home warm and comfy. Thanks for the great price[...]and making it possible for us DIY types to maintain our homes.Recycling our old pumps would be a nice added feature to this service though I understand it might not be economically feasible. In my case the pump seal was failing while the motor was still running fine. I could have possible just replaced the seals but because of it's age I went with the entire unit.

B&G pumps are usually the best...But this one would not run right out of the box...looks like the factory assembled this one by tightening one bolt (out of 4 ) to the max. causing the impeller to jam (and crack) against the inlet housing then pulled the other 3 down. Pex supply is shipping a new one out the next day ,prepaid freight as well as a prepaid pick up for the old one. HORRAY!!!!... I WILL CHECK THE NEW ONE BEFORE I TAKE TO THE JOB...

Good Product

Comments about 1/12 HP, Series 100 NFI Circulator Pump:

The unit came with all the bolts and washers. The only problem I had was the screw was on too tight for the electrical housing cover. Almost stripped the head trying to get it loose. Had to use a wrench with screw head to turn it.

Overall, the price was about half of what a local supplier was going to charge.

A very good pump!

By Joe W

from Dover Delaware

Verified Buyer

Comments about 1/12 HP, Series 100 NFI Circulator Pump:

A heating repairman came in to look at my old pump which started leaking and said it would cost a lot to repair and to catch the drips with a bucket until I replaced the entire system with a forced air system. Fortunately the old pump's series and model number label was readable. Your website is great when it comes to speed, convenience, and related service documents. The price was right and the part was delivered on time. Pump removal and replacement too less than an hour and the service/parts documents helped take away the nervousness of the job. Once connected and operating, I was amazed at how quiet the new pump motor was compared to my old one. It was hard to tell it was even running. All in all, completely satisfied !!!

      A:

      The pump is generic, so you have to buy the flanges also . They go from ¾-1 ½ I believe. When I replaced my pump I had flanges on the pipes already, but I had to replace them because they were in there since 1963 and they changed the style. It now comes with a O ring instead of a gasket.

      A:

      The pump comes with bolts and the right amount of oil for the initial
      lubrication. Assuming you are replacing the same pump all you need to do
      (after drainingthe boiler) is take the old one out and slide the new one
      in, hook up electrical and oil. Some installers prefer to leave the old
      pump housing to cut down on installation time.

    I'm replacing a B&G 100. Currently its weight is supported by the boiler fittings only. It seems that may be a bit too heavy for just the fittings. How do you suggest to support its weight? Thanks.

      Hi Phil,
      I've replaced the same pump on my system. It has 3/4" pipe that it attached
      to and I had no issues with the motor being to heavy for the regular boiler
      fittings.

      Answered on 10/1/2013 by Anonymous
    • VERIFIED BUYER

      A:

      Here's what I can tell you. We have 2 of these and they are supported by the
      boiler fittings.
      We've been using these pumps for many years (over 20) and have not had a
      problem regarding the
      weight. I see no additional support brackets on our system.
      However, it's been my experience that when you go to replace the pump
      an extra pair of hands would make the job a lot easier.
      The weight at the motor end will make the replacement more
      difficult if attempted by one person.
      Good luck !

      A:

      My B&G 100 motor is supported solely by the pump fittings as well. It was professionally installed, in my home, in 1997. In 2011 I replaced the pump portion because of some high pitch noises on startup and shutdown. The motor is still going strong, and the pump is quiet again. One nice thing about having the motor in this configuration is that if I overfill the motor oil inlets, the excess oil drops to a pan a few inches below, keeping it off the motor housing.

      A:

      I had the same concern when replacing my pump but assumed that if the old
      pump was supported by the fittings only, the new one should be fine - and
      it is. On my boiler the connection to the boiler is cast iron - this takes
      the weight and some torque when the motor starts. The fitting above is a
      iron flange attached to copper pipe - this also takes some of the torque. I
      don't think adding support is needed.

      A:

      I've sometimes thought the same question.
      I've included the manual for the pump but sorry to say that
      they don't get too specific regarding how much oil is excessive.
      check Section 6.1 Proper Oiling Procedures
      It states that you can use either SAE 20 OR 10w-30 weight oil.
      Generally, I would oil these monthly with 6 or 8 drops of oil as
      it gets constant usage.
      I also keep a spare pump on hand. It's just not worth my time to run around
      to find a replacement. We have 132 condo units here and I need to keep the
      hot water
      recirculating at all times.
      Hope this helps.

    • VERIFIED BUYER

      A:

      If you follow the recommended oiling frequency you will be fine unless you
      have a leak. If you have a little too much oil it shouldn't harm the pump
      but might make a mess. Too much oil can harm the motor or even cause a
      fire. Too little will harm the pump motor and bearings so if in doubt put a
      few (but only a few) extra drops in. I would not use 3 in 1 because it is
      too light and the moving parts will wear faster. Listen carefully to the
      pump when it is broken in and well lubricated. If you notice a change in
      vibration or noise try a few drops of oil. If the noise goes away you know
      you are low and need to top up.

      Hi Bren,
      Before the season of winter. Just follow the Manufacturer instruction to lubicate the pump with the specific oil(B & G). Can buy at Home Depot. Don't use 3 in 1 oil because will damage the pump bearing.

    • VERIFIED BUYER

      A:

      It’s hard to tell how much oil is in the pump.
      But you should be following the lubrication procedure in the manual.
      If you have never put oil the pump and it has been in service for some time
      add about ½ to 1 oz. of oil.
      An SAE 20 (non-detergent) is recommended or 10W-30 oil may be substituted.
      Don’t use 3-in-1 oil.
      Your local hardware store will have the correct oil. It will be in a
      container that looks like 3-in-1.
      Here is the link to the manual.

      A:

      I installed the pump for the same reason (leaking), but did not replace the motor (10yrs old and still going strong). Instructions do come with the motor and pump, but they are very general. YouTube probably has something better. The most complicated plumbing I've done is replace my water heater, and replacing this pump was easier than that. Here are a couple things I noted while doing this repair 2 yrs ago:
      1) turn off the water to the pump
      2) turn off the electricity to the pump motor
      3) place a drip pan under the pump to catch the small amount of water left in the pump and pipes
      4) after installation, fully oil the pump with the specified oil before using it for the first time, the motor too if installing that as well
      5) don't over tighten the connections at first, wait until the water is turned on and the pump is working, then if there are drips/leaks start tightening until they stop. This may take a day or two of observation.
      At least that's how I did it and I haven't had drips, or any other issues since the install. Hope that helps.

      The question is where is your pump leaking from. In the majority of cases the pump can be repaired. The question of cost depends on the nature of the repair required and labor cost from the supplier.

    My pump is approximately 35 years old. This morning it was noisy and sounded like a bearing may be going going, but then quieted down later. Does the entire pump have to be replaced? My system is serviced annually by my oil company. I'm sure the oil company will want to sell me a whole new pump, but the labor charges for replacing it may be more than the charges for repairing it. True?
