Inspector Pumphead’s Classroom: How to Replace a Pump Bearing Assembly

Welcome to another exciting edition of Inspector Pumphead’s Classroom! In this feature, we’ll be talking about various small, simple pump “How-To’s” that any homeowner, small business owner or facilities manager can tackle.

The purpose of this feature is to help customers become more familiar with the parts of a pump and give them the confidence to make the necessary fixes to keep the system running smoothly.

In this edition, Pump Products application engineer Nick, will walk you through the process of replacing a bearing assembly on a three-piece circulator pump from Bell & Gossett. The bearing assembly is the unit between the motor and the volute/pump casing. It contains the connecting shaft that powers the impeller, allowing the pump to move fluid.

From left to right: Motor, volute and bearing assembly with impeller

A good indicator that the bearing assembly needs a replacement, is if you hear strange noises coming from that area on the pump. If a seal or coupler snaps, you might hear a squeaking or shaking noise. You might also see traces of oil or water leakage in the pump area. Since the bearing is what keeps both ends of the pump functioning together, it is important to replace one right away if defective.

Pump Products expert Nick walks you through the replacement process in the video below:

The pump used for the breakdown is the Bell & Gossett 102210 HV NFI, a top flight circulator. The bearing assembly replacement package is the B&G 189166LF , which includes the attached impeller, a replacement gasket and lubricant.

*Note: While B&G repair parts are used in the example for this video, Pump Products also carries Taco pump repair parts, Grundfos pump repair parts, Armstrong pump repair parts and Wilo pump repair parts, among others.

Tools and supplies

–1 ⅝” combination wrench

–1 7/16″ combination wrench

–1 Allen wrench/hex key

–Lubricant (should come in the replacement package)

–Replacement bearing assembly

–Alcohol wipes

Process

As always when working on a pump, be sure to turn off the motor and shut down the water flow moving through the pump. For this process you will not have to remove the pump end from the piping.

Loosen the bolts on the motor end first

Identify the bearing assembly of the pump. It should be between the wet end and the motor of the pump.

First you will detach the motor end from the bearing assembly. For this attachment you will use the box end of the 7/16″ wrench.

Use the wrench to carefully loosen the bolts.

Pull the bearing assembly away from the motor, and inside you will find a spring-style coupler which connects the two units. This is where you will use your Allen key.

The motor disconnected from the rest of the pump

On each end of the coupler will be an indentation where it connects to the shaft. Use your Allen key to loosen the connections and remove the coupler.

Take out the coupler and put it and the motor down somewhere safe. Unless you bought a replacement, you will need to reattach the existing coupler.

Next, turn your attention to the other end of the bearing assembly, which is also connected by four bolts to the volute.

For this part you will use the box end of your ⅝” combination wrench to loosen and remove the bolts.

Loosening the bolts on the pump end

You can now remove the old bearing assembly. Inside the lip of the volute should be a rubber gasket. Remove the gasket and examine the lip area for any impurities or imperfections. This area is important for creating a watertight seal, so be sure to wipe it down with alcohol wipes or a similar cleaning agent until the area is clean.

The removed bearing assembly with attached impeller

Now you can install your replacement bearing assembly. This will simply be the deconstruction process in reverse. Insert the end with the impeller into the volute, reapply the bolts and tighten in a criss cross pattern to ensure a watertight seal.

Next, you will to have reattach the spring coupler. Remove the the piece of cardboard from the impeller shaft in the bearing assembly and find the right indentation groove. Match up the groove on the coupler and shaft, insert the hex key until it is flush to the area and tighten.

You will need to reattach the coupler

You will need to repeat the coupler process with the shaft end of the motor unit.

Once the coupler is secure, you can reattach the motor end completely and tighten the bolts.  Since there is no watertight seal between the motor and bearing assembly, you do not necessarily have to use the criss cross pattern.

You can see the coupler peeking out from the bearing assembly

Since the pump used in this example is not maintenance free, you will have to apply some lubrication (a bottle should be included with your package). Find the insert cap above the bearing assembly, fill with oil until the bottle is empty or oil starts to accrue at the top of the cap. Close the cap and you are ready to turn the pump and water flow back on.

So that’s it! It’s a relatively simple process. As always, be sure to examine your pump regularly and practice preventative maintenance.

If you have any ideas for other ‘How-To’ guides you’d like to see, let us know in the comments.

Inspector Pumphead’s Classroom: How To Change a Circulator Pump Cartridge

Taco 007 with a replacement catridge

Welcome to another exciting edition of Inspector Pumphead’s Classroom! In this feature, we’ll be talking about various small, simple pump “How-To’s” that any homeowner or facilities manager can tackle.

Next up: How to Replace the Cartridge on a Taco 007 Circulator Pump.

As the name suggests, circulator pumps are used to keep hot water circulating throughout your water system so that it is immediately available at point of use. For those of us who live in colder climates, the coming winter months are a particularly annoying time to have to wait for water at the sink or tub to heat up. The presence of a circulator pump ensures that hot water is always readily available.

The Taco 007 is built for quiet operation in hydronic heating, radiant heating, hydro-air fan coils, indirect water heaters, chilled fresh water and domestic water circulating systems. The cartridge style design means the actual circulating mechanism is contained in an easily serviceable or replaceable single unit. It is perhaps the most popular cirulator on the market and plenty are always available in stock.

In the video below, Pump Products application engineer Nick, who I have personally trained, will walk you through the process of replacing the cartridge, using the Taco 007-F5 pump and the proper Taco replacement cartridge (the cartridge package should also include a replacement gasket and spare bolts as well).

You can also purchase the full suit of Taco Repair parts.

You can also continue reading below for a written breakdown.

Items and Materials

The only tool you’ll need is a hexagonal Allen key (or Allen wrench). Make sure you have the replacement cartridge handy as well.

Steps

–Turn off the water flowing through your system. You do not need to remove the pump base outlets from the piping.

–Identify the four casing bolts.

–One by one, use the proper Allen key to loosen the bolts.

–Remove the bolts.

–Remove the motor casing from the volute. Inside the motor casing you will see the cartridge.

The cartridge removed from the motor casing

–The cartridge should be solidly in place. Tug gently but firmly until the cartridge is out of the casing.

–Discard used cartridge.

–Take the replacement cartridge and firmly insert into the volute.

The cartridge should fit snugly

–Firmly place the replacement rubber gasket into the lip of the volute base. The gasket is important for creating a seal.

The rubber gasket creates a seal

–Line up the base plate and the volute to the base and connect them. Be sure to match up the bolt holes.

Make sure all holes line up

–Insert the bolts and tighten only until each is roughly equally snug. Uneven tightening could cause leaks in one area.

–Complete the tightening on all four bolts in a crisscross pattern to ensure evenness on all sides.

And there you have it. It’s a simple and cheap process, one that any person should reasonably be able to complete. With winter upon us, making sure your circulator pump and cartridge are up to the task at hand is very important.

Happy Halloween from Pump Products!

Happy Halloween from Inspector Pumphead and all of us at Pump Products!

Inspector Pumphead wants to suck… your blood!

Now, if you’re a childless young-ish adult, you may have already had your Halloween celebrations on Saturday.  You may have Instagrammed your ironic, edgy or topical costume to gain a paltry amount of “likes” before waking up in a hungover haze on Sunday.

However, Halloween is really a holiday designed to let little kids eat candy and it is today, October 31. But what is the history behind Halloween?

History

Most historians generally agree that the strongest historical influence for Halloween is the various pagan folk festivals celebrated by the Celts. Many of these festivals marked the end of the harvest season and the beginning of the “darker half” of the year or winter.

Rituals and games associated with the future and death were popular. People often went house-to-house in a costume, singing songs in exchange for food. This was known as “mumming” and is the precedent for trick-or-treating. Later celebrations were influenced by the European Christian celebration of “All Hallows’ Eve,” in which the faithful would often dress as saints or martyrs in an act of commemoration.

The spirit of that holy commemoration is now represented by people dressing up like The Joker.

Halloween Creep

Do you feel like people have been talking about or celebrating Halloween since basically late September? You’re not alone in noticing the proliferation of what has been termed “Halloween Creep” after the similarly named concept “Christmas Creep.” The website Consumerist took note of the phenomenon last year when a reader wrote in about seeing Halloween decorations for sale in July.

Of course, after today, expect to see Christmas decorations and hear “All I Want for Christmas Is You” everywhere you go. It’s part of the relentless, insatiable march of capitalism where we must be given things to buy and consume. So enjoy I guess.

Popular Costumes for 2017

Besides your standard variety of zombies, witches, werewolves, or vampires, look for a lot of Pennywise the Clown from It or variations thereof. Also: Belle (from Beauty and the Beast), Wonder Woman, Donald Trump and anything from Stranger Things and Game of Thrones. People really like dressing up as their favorite characters from popular culture. Who knew?

Think About This

Yeah.

Fun Fact

According to USA Today, Americans will spend close to $15 billion USD on Halloween this year. The spending includes costumes, candy and decorations. That’s bigger than the GDP of Jamaica, and most of that spending will be done by millennials. Darn millennials – get your priorities in order!

Happy Halloween! Enjoy your candy responsibly and don’t forget to book a dentist appointment.

Hazardous Areas

*And now a brief word on hazardous areas, as defined by the NEC and NFPA:

Class I, Division 1: There are three different situations that could exist to classify an area as a Class I, Division 1 location:

–Ignitable concentrations of flammable gases or vapors may exist under normal operating conditions.
–Ignitable concentrations of such gases or vapors may exist frequently because of repair or maintenance operations or because of leakage.
–Breakdown or faulty operation of equipment or processes might release ignitable concentrations of flammable gases or vapors, and might also cause simultaneous failure of electric equipment.

Group C: Flammable gas, flammable liquid-produced vapor or combustible liquid-produced vapor mixed with air that may burn or explode, having either a maximum experimental safe gap (MESG) value greater than or equal to 0.45mm or less than 0.75mm, or minimum igniting current ratio (MIC ratio) greater than 0.40 and less than or equal to 0.80. Example: Ethylene – 497:3.3.5.1.3.

Group D: Flammable gas, flammable liquid-produced vapor or combustible liquid-produced vapor mixed with air that may burn or explode, having either a maximum experimental safe gap (MESG) value greater than or equal to 0.75mm or minimum igniting current ratio (MIC ratio) greater than 0.80. Example: Propane – 497:3.3.5.1.4.
