This is a good demonstration, but if any rust has built up on the shaft under the sleeve, the sleeve will become next to impossible to remove. Heat and small pullers may have to be used. If that doesnt work, a hole saw the size of the o-ring groove can be used so the seal plate can pass over the sleeve and you can bang it off with a hammer. Commonly I put the whole bearing assembly in a lathe ( less impeller) and machine it off. Note to techs * Put a small amount of anti-seize under the sleeve during re-assembly.
I have also used heat through the small fitting where the seal flush goes, this usually goes pretty good. This guy is at the Taco factory taking a brand new pump apart. Two different animals
It's literally the exact same. The biggest problem with these seals is removing the sleeve. Heat+pullers, if that doesn't work, a hole saw the same size as the o-ring groove will suffice. Then you can remove the seal plate and egg the sleeve to remove. Anti-seize under the new sleeve will help the next tech 5 yrs down the road.
What a bunch of BS!! This guy is tearing down a brand new pump, let's see them do a video on a pump that been in service for a while as the pump doen't come apart all that easily. There are better pumps on the market that do disassemble easily after they have been in service.
Of course they do, they are a manufacturer, not a service company or museum of old & improperly maintained fluid handling equipment. This is no different than what EVERY other manufacturer does in similar videos. Maybe you think they should have pipend in six 20" double suction split case pumps, complete with overhead piping & obstructions, rented a crane or picker & had the demonstrator along with 3 or 4 additional people to maneuver the top hat out of the way? Wire everything up, live to the motor pecker-head & display every last thing anyone working in the field should expect to encounter? As to the remainder of your blurb, I have had hands on nearly every type & make of pump used in HVAC & process service applications within the US, a few territories & overseas. Everything from single & multi-stage centrifugals, lobes, screws, double suction, vertical inline, end-suction, VMS, diaphragm, close-coupled, coupled, direct driven, permanent & replaceable mag, including split mag, split case, axial, turbine, mixed/combo, canned, metering/dosing, grinder, chopper, slicer/cutter, emaciator, circs, self-priming, vertical column, regen & PD, jets, diaphragm, recip, piston, RR, gear, plunger, progressive, & rotor vanes, in open, closed & mixed systems, for WW, HVAC, process, chemical, solids, storm, muni, sewage, potable, FDA (pharma & food/bev), agriculture, irrigation, fabrication, geothermal, fire, chemical, energy recovery, reclamation, RO/DI, desal, mining, condensate, deaeration, seperation, mixing, boiler feed, & well applications. Flows ranging from tenths of a gallon per hour (injection dosing at ppm levels for mass or volume based solutions) to nearly 100,000 GPM. In terms of applied energy or required force, differential pressures conveyed via pump/driver combinations, they've ranged from a few feet of head (TDH), to upwards of 50,000 PSI. Lift, flooded & pressurized suction systems, pumps in series, parallel, & with or without bypass, not FVD bypass, but a number of those as well. That's another issue for another day. The biggest factors, the most relevant in terms of ease (or difficulty) of serviceability, in my experience, is & always has been preventative maintenance, environment & application. Pumps, particularly these days, are nearly commodity items in nature. Manufacturing advancements, computational fluid dynamics advancements, available modern design & scalability tools have all improved significantly. Manufacturing tolerances have become more uniform for parts, efficiency has risen (particularly items conforming with DOE/HI/AHRI/ANSI/API/EuP-EC/ErP/etc standards & directives) & engineers & designers have started understanding the ways they''d previously obstructed & hindered themselves with outdated specification requirements. There are some small items that set each apart, but those differences are fewer & fewer with every passing year as patent terms expire. Further, while there are without doubt some pumps with more easily accessible seals, and even some without seals &/or liquid-end bearings, external seals, etc.., they are not always suitable or even ideal for particular applications or installations. Many these days like the vertical single-stage inlines. No pump bearing & some have no, or no internal seals. I for one would not want to work near one over 60 HP, maybe 100 HP max, depending on the location & design of the system. Do a little research on moment of inertia, not to mention motor bearing stresses & additional footprint requirements. Speaking of which, how do you service or change a motor out on a 300 or 400 HP vertical inline? How much overhead clearance is required, what equipment & how much labor is required? Doe the manufacturer use OEM or specialty seals? Proprietary OEM motors? I know of at least one other US based pump manufacturer that sells a lot of end-suction pumps like this. Instead of an off-the-shelf JC #21 seal, they use proprietary cartridges, costing 400% to 800% more & with as high as 12 to 16 week leadtimes on occasion. If nobody stocks it & a process goes down, what is the cost of any associated lost production. There is a lot that goes into the design of a pump, they each have their uses & ideal application types, just like every other type of equipment or tool. There is a reason pros carry specific tools, you know this, the fact that you watched the video tells me as much. Nobody, no single person on this planet that is outside of the trades or engineering, watches pump videos, except maybe students. Being a pro, you wouldn't use your no-hub wrench as a hammer, right? Nobody wants to be the jobsite butcher that everyone nicknames Wrammer. Similarly, pumps apply work, just like a tool & every tool has certain tasks and instances where it works optimally.
Hello Jose, yes of course it is always easier when working with a pump in this condition and yes it is always harder when there is corrosion involved. If all working pumps were in this condition for the entire life of the pump, it would be a perfect world. However, in this video, we wanted to show the correct method and steps to replacing a seal kit. Thanks for watching
Good Day Jim, Thanks for watching the video on the FI pump. Speaking with the engineering department, we have been installing seals like this for many years. If you would like to talk or meet with one of our representatives in your area, please use the below link to locate the nearest one. www.tacocomfort.com/rep-locator/
Disappointing video , any pump mechanic can tear down a brand new pump I repair pumps that have bean in service for 20+ years. And never ever should you pry on the impeller. You should know better and Taco should too

Note to techs *

Great instructional video! Thank you for your help!
Good Video but need to add the rest of story about realignment of motor and coupling
great video thanks
I noticed that you didn't use retaining compound on the sleeve. Is it better to use that or not?
Any chance of making a video about rebuilding the J frame assembly?
I'd like to see a video on the KV series pumps

Mahk? Is that you? I thought you only did Chevy Commercials?

Yes, And how do you remove the seal sleeve when the pump is used and rusty from seal failure? Even my grandma can do it with a new pump! Poor design.

What is the size off seal can i tel please i have to buy seal
1549-3brp
This video is not correct. He puts grease on the shaft seal.

LOL. Let me see you replace a seal on a pump that hasn’t been taken apart for 20 years.
Tom, agreed, it is much harder as they age. My knees remind me every time I get into a boiler room!
Never, never! use pry bars to remove the impeller. Otherwise thanks for showing show it comes apart.
