Brushless 12V Mini Water Pump 6-15V DC, 0.5-4W, Silent Ceramic (Submersible (ABS))

UPDATE Nov 30, 2024 (about 4 months in service): The fault of the system designer (me) and not the pump: The system accumulated an air pocket that made its way to the pump, resulting in the pump being starved for water and running dry for at least several hours. Remarkably, the impeller and shaft weren't harmed; however, the was no water to cool the electronics inside the epoxy encapsulation, so a hole melted in the side of the pump chamber, letting water seep into the electronics. Now the pump is dead. (Again, my fault.) (Note to others: Always position the pump motor downwards, so that the unit is cooled and the shaft lubricated with water.) Other than that, the pump seems to be in very good condition. I put a replacement pump into service on this day, and we shall see how long it lasts. I hope to get at least a year of service if the pump lasts the original burn-in period (a week or two). I will continue to update (I promise).ORIGINAL REVIEW: I bought this pump (the PPS verson) to recirculate coolant (deionized water) for a semiconductor switching array on a solar system. It will operate during daytime hours 365 days per year. How well will it hold up? I will update this review to let everyone know.(My history of pump failures: This is my third pump version. The first was a nonsubmersible pump of a similar type, except higher capacity (excessive). The original pumps were great, but they cheapened the design such that the pump wouldn't last more than a year. The second design I used was a miniature submersible 110VAC fountain pump. Great price, but it failed after 10 months due to water penetration.So I gave up on the submersible pump concept.)This little pump creates a lot of flow, and it is essentially silent (unlike the first pump I used). It would be great if the nipples were a bit longer, but I suppose they are long enough. I have mine running at 12.0 VDC. Again, I will definitely update this review when the pump fails (I promise). If I haven't updated this review, then you can assume the pump has been running every day, all day (daylight hours), without failure.

I bought item: B08Z3BF1X8 from Amazon. The pump was a piece of JUNK! So noisy! Even with headset on it was still VERY LOUD! It died very quickly. Left a review on it. I was ok happy with the rest of the GPU cooler setup. I bought this pump to replace the junk one. So far VERY happy with it! QUIET! Can't hear it running. Circulates plenty of water. I don't leave this computer on for more than 12 hours at a time so I can't tell you how it will do with continuous use but for the cost I don't think you'll beat it!I cut the molex connector off the old pump and soldered the new pump to it so it uses 12V from the computer power supply and turns on and off with the computer.The input port on the pump will fit the tubing that comes with B08Z3BF1X8. The output requires some engineering. 1/4" clear tubing about an inch long put on first and then slide the kit tubing up over that and then clamp. Mine has not leaked and handles the pressure fine. If this one goes out, I'll buy another.

Used this to build a diy self enclosed submerged phosphate reactor and filter for a nano reef tank I built. Worked great and was powerful for flow but honestly a bit louder than I liked. Ended up finding a nano HOB filter and swapped out. Already found other uses though and can easily be spliced into and existing USB cord and powered with a phone charger.

I use these to power a DIY CPAP humidifier tank re-fill system I put together. The outlet is just about perfect for 3/8” OD PE RO tubing. Give it a little bit of a heat gun and it will slide over easily and cool down to a fairly tight fit. Fits nicely down a gallon jug (for distilled water) at an angle and worked down in.

So firstly this doesn't come with a plug attached and they do not mention it. Secondly after setting it up with a micro USB the motor itself was EXTREMELY loud then stopped working all together within 2 minutes max. Don't waste your money

I bought 3 of these to water 3 flower baskets when we're away- pump water from three 5 gallon buckets (no exterior faucets on my condo). I always do trial experiments on items like this before installing them. This submergible pump running on 6 volts pumped 1 gallon per minute at a 3 foot head and only drew 1/4 amp. Very impressive. I throttled down the flow to 1/2 gallon per minute with no pump issues. A "JVR 12 volt timer switch" (from Amazon) will turn the pumps on for 1 minute every other day.

A bit loud as other reviews have stated but works really well.The output nozzle is absolutely not 1/4", my calipers say it's .3". I got some 1/4" drip tubing along with this and managed to make it fit by hitting the tubing with a heat gun (a hair dryer would probably do the trick as well).Just be advised the specs are not at all accurate.

I am using this pump to move water on my child's water table back to the upper portion to rain down. This pump moves enough water to keep the feature operating with no problems. The pump does need to be primed but that is no issue. It is small enough to keep out of the way and still effective.
