Recirculating Pump with 1'' FNPT Flange

Quiet even on speed III. Tons of flow for a small bore pump. It's been in service for 3yrs now on speed II with zero issues. What more could you ask for, don't like it? buy a Taco for 4 times the cost.

A very good product with a good price I have ordered 2 of'm,need to calculate w.c. Size etc to make it work properly!!! It's not for beginners !!!

The pump gets surprisingly hot, but runs cooler at the lower speeds. I give it a four-star rating because it’s quiet, cheap and easy to install.

UPDATE: Contacted Seller, They very quickly sent out another pump. This one runs well, and doesn't screech like the old one. Changing review to 5 because customer support was actually pretty decent. You can't make a million good parts, it just seems I always get the 1 bad one of whatever I order! I replaced my pump with this junk at the end of last heating season, fired it up this season, and it lasted about 4 days and then died! Useless junk! Buy a grundfos or taco

Out door wood boiler burnt down, installed this and seems to be working for the past 2 months, it is extremely quiet, u can hardly hear it, I have to put my hand on it to tell if it was running, the seals are holding up and is t leaking, it has 3 nice variable adjustable pumping speeds, definitely recommended

I purchased three of these pumps and three different times. The first of the pumps worked for one day before I removed it for another solution. The other two were purchased for a job that got delayed. The one pump that worked only worked in one physical orientation -- the one that the manual says NOT to use. The other two didn't work at all. All three pumps demonstrated a loose main shaft when shook. All thee pump flanges had 1 inch iron pipe thread that was to large to seal against leaking. I have never met, nor can I imagine a lower quality pump.

Taco and Grundfos are expensive, they work well but this WiseWater pump is doing the exact same thing for 1/4 the price! 3 speeds allow me to tailor the heat I want delivered to my out building instead of being stuck at one pump speed. Very impressive!

Nice circulator but doesn't fit. 99% of circulators sold all have the same flange and body spacing measurements however this brand is off on both counts. I am replacing a Taco 007 circulator and piping is set in place and not able to be retrofitted. I did not expect this problem, and I have to return this item and search for an adequate replacement. If you are replacing a conventional circulator, keep on looking and double check the fitment specs. I learned the hard way.
