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...

              I installed my series 100 NFI pump on Oct. 2, 1990 and it just sprung a leak. I'd say 23 1/2 years of working with not a single problem says tons for how good this product is. I will be buying a new one shortly to replace it.

                    Owning apartments requires a committment to providing comfortable, maintenance free living to our tennants. In one of our buildings we provide the boiler heat for the tennants. It is an "eighties" system and the old circulating pumps had given it their all, especially one squealer! Due to their age, a technician strongly suggested replacing all the pumps(4). I was quoted with what I thought was a high price for the replacement pumps. Searching the "net" I found PEX, got the best price, plus free shipping, and an extra price incentive! Got the pumps in 3 days, had them installed, and no more worries of pump failure, especially in this brutal winter.

                                                  The circulator is used to provide hydronic heating for my basement. It is easy to install and the configuration can be easily changed to suit the circumstance. The instructions and the lubricating oil are provided. Once the maintenance instructions are followed the unit will perform effectively.

                                                        We were forced to replace the old circulator, due to the failure of its coupler. We quickly found that the pumps mounting flanges where fitting so tight it became difficult to install the new pump. We recommend everyone purchase an additional set of mounting gaskets/seals. Having extra gaskets on hand saved the day for us!

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.

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 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.

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?

You may want to remove the pump,turn it on the side and using a motor or contact cleaner spray with a long thin tube, clean out the port and then add the proper oil.
