Good pump for the $

So I was a little skeptical to use this on my outdoor boiler that heats my house. It took some engineering to hook it up since it comes with a plug(my other one was hardwired) but I got it. It works great. So far so good! For half the price of my original pump. I'd buy it again

Used this pump to circulate water through the empty and cleaned refrigeration coils in an old freezer that I can pump either cold or hot water through to cool or heat the freezer interior thus making it a retarder for slow rise doughs and a proofer too to speed up the rise. Very pleased with the sound level as it is whisper quiet and the flow even with the long runs between heat exchanger and freezer coils is still fine.

Great price worked great did the job . 1time use.15 months later 2nd time to use and did not work.So great but one shot wonder . Flushed ram 3500 heater core

First one was DOA, will see what number two is once I get it.

My DIY project was to add a hot water recirculation loop to provide hot water to the kitchen sink and upstairs shower. The original 40 year old copper pipes are very long taking forever for hot water to arrive and and uninsulated that would cool off quickly after water flow stopped. I installed a new insulated 75' long 3/4" PEX loop to bypass the existing lines that used the BOKYWOX 110V 93W NPT3/4'' 3-Speed Food Grade Pump to return hot water to the water heater cold water supply inlet. The pump is activated by a 12VDC N.O. IR motion sensor at both locations which trips a momentary input to the UCTRONICS DC 12V Programmable Multifunction Time Delay Relay. The timer is programmed to run the pump for 3 minutes, off for 5 minutes, and repeats if motion sensor trips again. At the highest flow rate it takes about 60 seconds for hot water to arrive from a cold start. The pump appears well built, quiet with no leaks. After about 2 months the pump is providing excellent service and would buy again.2 check valves are required, one to prevent hot water from entering the cold water loop and the 2nd one on the pump discharge to prevent backflow when pump is idle. Be sure to purge air from the return loop on initial startup, as this loop is vapor locked and pump is dry.

This pump was bought to replace a frozen up pump in a boiler system. The pump pretty much dropped in place and attached to the flanges that were already there. Minimum fuss. I think this pump might be very slightly longer from mounting flange to mounting flange than the previous one. However it did fit and has been working now for about three weeks. Seems to be quiet enough and is doing the required work. As for durability… I don’t know. It seems well constructed but time will tell.

I actually used this as a replacement pump for a 2 year old Bestway/Coleman Lay-Z-Spa. My impeller and impeller shaft were irreparable (I tried, trust me), so I just bypassed the pump. I left the old pump in place, disconnected the power to it, and installed it under the "egg" between the intake line and the old pump intake. I sort of just cut the line that was there and used clamps to clamp it to this pump. So quiet you can't hear it and it has really nice constant flow. I can still use the heater in the original egg unit thing because the flow sensors detect water movement. I didn't want to drop another $350+ on a new one when everything worked but the cheap pump they nestled in there. I'll try and get some pictures and a better explanation, as there is very little to no information about these inflatable spas online.I'm sure this thing works great for what it was designed for as well.
