Grundfos 526062 Cartridge Kit for Select UP Series Circulators

User Reviews & Q&A Summary:
A replacement cartridge kit used to service select Grundfos UP series circulator pumps in heating applications by replacing the pump's internal cartridge assembly rather than replacing the entire circulator.
Key Features:
- Replacement cartridge kit for select Grundfos UP series circulators
- Listed for heating applications (as shown in product specs)
- Identified as a replacement part (as shown in product specs)
- SupplyHouse "Product Highlights" reference the UP26-96 and UP26-99 models
Compatibility & Applications:
- Listed for use with:
- UP26-96 115/230V
- UP26-99 115/230V
- SupplyHouse Q&A indicates compatibility for additional specific models, including UPS26-99BFC, UP26-99BF, and UP26-99F
- Must only be used where the manufacturer specifies this exact part number: 526062
Installation & Operation Notes:
- Installation should be performed by a qualified hydronic heating professional or technician familiar with circulator service practices.
- Refer to the specific circulator's service documentation for correct disassembly/reassembly steps and any required setup checks.
- Grundfos guidance for spare parts selection emphasizes using official spare-parts resources (such as the spare parts finder/product information tools) to identify the correct service kit for a specific pump, including selecting the correct production details when required.
- User feedback includes an installation-related note that bearings are lubricated by the pumped fluid and that proper mounting orientation matters; follow the pump's official installation/service guidance for required orientation and piping configuration.
Maintenance & Troubleshooting:
- This kit is typically used when a circulator is no longer operating correctly but the pump body can remain in place, allowing the internal cartridge to be replaced.
- Review themes commonly link cartridge replacement to symptoms such as loss of circulation (including reports of an impeller issue) or a pump that won't start (including reports of a seized shaft), with replacement restoring operation.
- If problems persist after replacement, consult the pump documentation and spare-parts resources for model- and production-specific troubleshooting guidance and correct kit selection.
User Reviews & Q&A Summary:
- Reviews commonly describe the cartridge kit as a practical way to "rebuild" the pump quickly by replacing the cartridge rather than the full circulator, with several noting the job can be completed in minutes once the pump is opened.
- Some reviews raise durability/reliability concerns based on their service history, including reports of shorter-than-expected life in certain installations.
- Q&A responses from staff state the 526062 cartridge is the correct replacement for UPS26-99BFC, and that it will work in UP26-99BF and UP26-99F models.

Like A New Pump, But Easier
Only 4 screws to pull the pump apart, and put this new cartridge in. I had our pump rebuilt in under 10 minutes, and we were again up and running.
I don't know why, but we have had a few of these pumps where the impeller broke right off and would stop pumping. When that happens, our boiler gets an error of too high of temperature and it shuts down. Whenever that has happened, we rebuild this pump, and it works like new again.

Lifetime is Poor
I have 5 of these units in a solar installation. My experience, in spite of the Grundfos reputation, has not been good. Over a 10 year period I have had to replace 3 of these cartridges.

Glad I found Supply House
Supply House was less expensive than competition and free shipping. Shipped very quickly.Turns out I didn't need this cartridge kit now but will no doubt in the future. They're getting harder to find and the price has skyrocked. I'm stashing it away. If I have future needs of this nature, I'll check with Supply House first.

Lasted only 8 months
Growing concern over long term Grundfos reliability.
But, the support from the Supply House team could not be more friendly and professional. Gotta love those guys (and gals). Best I've ever worked with.

Early failure
Lasted 8 months, seasonal floor heat system, shut down for summer. Shaft seized, wouldn't start. Removed and freed turning by hand. Replaced under warranty but now don't trust the design. Customer not happy. Neither are we. Tech support from Grundfos essentially non existent.

Can't express in words how happy I am
Seriously, right now I almost want to cry I'm so happy. My pump started making noise recently, and it escalated quickly. It wasn't that bad at the pump, but the copper pipes in a 2 story house make a really good amplifier. It was SO loud I had to turn on a fan at night to make background noise so I could sleep. Next week, we have a whole week of temps barely hitting the double digits for a high, so I needed this fixed ASAP. When I found out that just the cylinder could be replaced, and I verified with Supply House that it would fit my pump, I had to break down and order one. Didn't want to spend the money, but I had to. Now, I'm sitting in a quite (finally!!!!) and warm house. Thank you SO much for overnight delivery. The peace of mind I have right now just can't be put into words.

cartridge kit
I purchased this cartridge for my ground source unit, shipping was extremely fast, and the part dropped right in. Took about 15 mins to fix my problem. Supply House is now my "Go to" for all of my ground source needs.

Very happy!
My geothermal unit has two pumps, they lasted 10 years so after replacing them I bought two more so I would have them 10 years from know. Cheap insurance and a great product that's easy to replace. Thanks so much.

Worked perfect.
Instructions were straight forward. Worked perfect. Washer included was big help. We again have heat in our floors without hiring a plumber.
