12V-24V DC Dry-run Protection Brushless Submersible Water Pump, 410GPH, for Solar Fountain, Fish Pond, and Aquarium…

2025 Spring update: Took the pump in over the winter months. Cleaned it with some vinegar today and brushed away all the dead brown algae. Hooked it up to my solar panel and whoala - still works great. Hopefully it’ll be another spring/summer/fall of use.UPDATED: A year later…. Took this out of the shed where it has been stored over the winter. Was very curious whether it would be fine. YES! Worked right away. No issues. Still love this pump.ORIGINAL: I've purchased several small solar stationary pumps in the past but they either have little power or die after a year. It was time for another replacement when I found this pump on Amazon and decided to give it a try.The box it was shipped in wasn't great and had some damage but fortunately the contents were intact and undamaged. I open the box and noticed this is a LARGE pump. It's like a brick! I was dubious about how it would work and tested the solar clips to a 9 volt battery and was floored with the pumping power. I appreciate that it has a flow rate adjustment on the side to raise or lower the water pumping level.Next I hooked it up to a 12W 12V solar panel. It works great! Better than any pump I've used before. The only issue is that it is so good that I need to dial the flow rate to almost the lowest setting for my birdbath otherwise the water is too high and partially splashes out of the birdbath bowl. Again, glad it has the adjustment.Now here is the thing with this pump though... as it is a large pump and the intake filter cutouts is also on top of the pump, the water level needs to be completely above the pump. The pumps I have used in the past have had intakes either at the bottom or side. With this one being also on the top portion and due to it's size, you will need a large volume of water. Make sure your basin is deep! So this might work better for a water feature basin than a birdbath depending on how deep your birdbath basin is.Now we'll wait and see how long it lasts...

This pump is smooth running, doesn’t use a lot of energy to run and has plenty of power to move the water. Using it in my pond and running it with 45 watts of old solar panels. All good and happy with its performance.

EDIT: It died after 3 years of constant use. It began starting intermittently and then stopped completely. I have cleaned water sensor electrodes and checked it with a different power supply. It is dead. The assembly is probably sealed and not serviceable so I will be looking for another pump, It has been an OK value for the price I paid but sealing new wire and turning a heavy fountain over will be a hassle.I have replaced a 110V pump in a fairly large, three bowl fountain with it and it goes strong. I have Philips Hue lights throughout my backyard and this pump saved me some money since I was able to wire it to the same 24V DC line as the lights ( Philips Hue outdoor wiring is "always on" 24VDC). It has been running without any problem since. It makes funny start/stop noises when it eventually runs out of water but that is about it. I have not even cleaned the filter once yet. Just add the eco-friendly enzyme to the water to minimize algae growth.

I have actually purchased 4 of these 12V pumps. None have lasted longer than 12 months, and the last one failed after 3 months.

The media could not be loaded. From the box to the hydroponic system in less time than writing this note.Pump is generic. Standard DC plugs, standard pipe threads. Went straight into a hydroponic system and pumped water in seconds.Excellent value for the price. I may be ordering several of these pumps for projects in East AfricaTo see the complete swap out from defective pump to circulating water and nutrients again, go to GreenUrbanIslands.

I am using this pump in a small, decorative fountain. It is easy to use, compact, relatively quiet, and is ideal for this application.So, why only three stars? This is the third pump I have used. The previous two failed after about two years. What happens is the pump starts pausing occasionally for a few seconds, then restarts. The pauses become more frequent, and longer, over a few months until the pump needs to be replaced.When I replaced the latest one I decided to dig into why the old pump failed. The answer seems to be simple. The water level is sensed by two small metallic bumps (electrodes) on the side of the pump. If both electrodes are under water there is conduction between the two electrodes (through the water) and the pump operates. If the water level falls, there is no longer any conduction, and the pump cuts off. The problem is that, over time, corrosion builds up on the face of the electrodes. The corrosion is non-conductive, so the pump things the water level is too low and cuts off. I scraped the corrosion off the electrodes, and the pump worked perfectly again.

I have been using this pump in my pond for a fountain for a couple years. I do not have access to grid power at the pond, so I have (4) 100 watt solar panels that charge a pair of 12V 100AH AGM batteries. I have the batteries wired in series (24 volts) and they will run this water pump 24/7. Very happy with this pump.

Bought the "12V-24V DC Dry-run Protection Brushless Submersible Water Pump, 410GPH" in March 2021 for $36.86. It ran fine up until March 2023 when it died.My fountain unfortunately gradually runs dry after a couple days of water splashing overboard. This is why I bought this dry-run pump because I can't always refill it immediately.Taking it apart the rotor is relatively clean and seems like it should still work. I suspect the motor may have overheated causing internal damage to the windings.If you keep the pump submerged you probably won't have this problem. That said, you won't need a dry-run pump. So what's the point of buying this pump if it eventually dies from lack of water?The price on Amazon is now $59 as of May 2023. I won't buy another one but will look at other options.
