Update Aug 3, 2024: The first pump died after about 10 months of service, running constantly during daylight hours and not running at night. The impeller core was in good condition. The failure was electrical, due to water intrusion around the cord (evidenced by minor corrosion on the copper wires). A resistance measurement across the electrical cord indicates an open circuit. The pump had been submersed at a depth of about 4-5" in deionized water. I had hoped for at least a year of service per pump, so I'm deducting a star - from 5 to 4. It's still a very economical pump, but I will have to keep it on an 8 month replacement schedule, which is sort of a hassle. ---------------------------------------- I needed a new recirculation pump to replace a pump with a worn bearing (that was squealing). It is used to circulate deionized water through a large heat sink and then through a small radiator with a fan. The "real" pumps are super expensive, with lots of focus on looking "cool." I don't need the "look," and I also don't need to cool the CPU and GPU of a power-hungry gaming computer. So I put this little pump in a plastic storage container with a hole in the snap lid. Water tubes and electrical cord go in and out through the hole, and the hole is sealed up with "dumdum." Easy-peasy. The assembly sits on top of the rack housing, where I can observe the water flowing. No need to bleed it. Just plug it in and go. This pump does not make the design mistake of my previous pump, which is to have plastic friction parts against plastic. It's got a stainless shaft, so it should last much longer. And yes, never trust expensive equipment to a cheapo pump: My solution to that is to place a temperature sensor on the heat sink that will shut the whole operation down if it goes overtemperature. The circulation rate is perfect - just a steady flow. Very quiet. Only 3W. Enough head to do the job. Best of all, I have a spare one in stock, if I need to replace it. And replacement will only take maybe 5 minutes :-) Read more

Great little pumps for the price. I’ve used them in my fountain making many times. Read more

Overall these do work well. I have a gravity waterer inside for my animals and wanted something to keep the water moving for my kitties. Works well for that except the fact the two suction cups just aren't enough to keep it held down. After running for a few hours it works itself up a little and makes a terrible loud vibration/motor noise which then deters my animals from drinking from the bowl. Fix the suction cup issue and this will easily be a 5 star product. Read more

The media could not be loaded. I'm a mixed media artist working through a number of prototype projects, one of which a recycled, up-cycled, indoor meditation salt fountain. I ordered this pump to try out my ideas and it definitely did the trick. It does have options for flow settings, I have it set on low. Read more
