I have now made my second purchase of this item!
My first unit only lasted about 2 years before it failed to circulate water in my 3 zone residential boiler for my home.
(In my opinion, a pump in this application should last for MANY YEARS before it fails.)
I ordered another identical pump to get my boiler back up and running to heat my home here in Minnesota.
(It's NOT uncommon for us to get
Sub Zero temps. In our winter season.)
If a pump like this unit would perform and last for at least 5 years, I then would have rated it with a FULL 5 STARS!

I would buy, or sell, this product again.
I installed a pair of these in my hot water heating system, replacing a couple of antique 1/12 HP Bell & Gosset circulators. No more oiling, coupler replacement, or motor mount replacement. Less noise. They are now 32 years old. Painted blue, believe it or not. Today, for the first time, one of them didn't start when called. A couple of taps with a hammer, and it started right up. That's the pump's lifetime service record, so far. The other one has never failed to start. Uses about 1/4 the electricity of the B&Gs. I've been installing Grundfos pumps, of all shapes and sizes, ever since ever since.

so far so good
Sales rep was courteous and timely in locating the right replacement pump and the plumber installed it. So far so good. I saved a bunch of $ - am so grateful. Now I want to know how to recycle the old part - good metal we don't need to be throwing away cuz there is no "away". Great pump, first one lasted 25 yrs. Lets get back to building to last and recycling and repairing jobs.

Good Product
My hot water heater circulating pump went out and I got quoted a very high price by a contractor. I found this equivalent pump online for substantially less cost. It shipped in a timely fashion and has been working well for a month now.

Great product
Had my old unit go ban after 13 year of use and placed the order for the replacement. Noticed it was not the same model number and called the support team to confirm it was the replacement. Came quickly as promised and they had THE BEST PRICE out of all the other sites I checked.

Asked by brett 16 years ago
Add your answer
Verified Reply- Pexsupply StaffThe pump size may be the issue. If this is an open system you should use a bronze or stainless steel pump. You may want to try the Grundos 52722518 pump.

Brett, I'm not an expert, but it seems your volume of water (GPM) delivered by your pump might be the problem. Too much volume of water going through the boiler might be the reason for the low temp. Lower the Volume and speed and the water temp should increase. Is it a Multi speed pump; can you slow it down?

Q: The pump suddenly stopped working after being un-pluged for about 3 weeks. We have had a problem with warm water in our cold water lines. Any suggestions?
Asked by Eric 16 years ago

Verified Reply- PexSupply StaffThis pump is not used for a plumbing system. Cast iron pumps are not to be used on an open system as it will rust and deteriorate, which is most likely why it is no longer functioning. In regards to the question about the warm water in your cold lines, I would check the piping to make sure it is properly piped for a re-circulation system.
