Jecod DCP Sine Wave Water Return Pump (DCP-2500) by Jebao,Black

This is my first foray into the world of DC variable water pumps, I have a massive collection of ac pumps and never considered anything else before a few months ago. You will not find a better, well thought out pump on Amazon in this price category. I know this because I initially bought a different model that was $10 less, and none of the fittings were even remotely compatible with any type of widely available metric or imperial tubing or pipe in the US. This DCP 3500 has a hard pipe connection that is an excellent fit with 3/4" PVC, which is what I'll be plumbing with, and a nice tight 3/4 barb which I'm using for testing purposes. No rigging anything together, it all works out of the box. Noise was not a contributing factor in my purchase, but it is the quietest pump I've ever owned. Even without suction cups, just sitting in the bottom of a 5 gallon bucket, it's completely silent. The power is incredible for such a small pump, an ac pump with this amount of flow would be 1.5x the size and 3-4x the wattage. Speaking of wattage, I live off grid, and water pumps really start to add up when you're using several, I'm so impressed with this pump I've already ordered another 3500 as a backup, and a 2500 for moving the fluidized bed in my sump/for water changes. The variable flow is such a cool feature (I realize this is inherent to DC pumps in general), being able to match the 4 overflows that are feeding this without a ball valve and a guess is pretty awesome, and it pumps great even at the lowest setting, at least in initial testing. The value is incredible. Compared to the other pump I initially purchased, everything just works with this one. Don't settle for weird fitting sizes that are going to require major modifications to make work, I can't trust that in a permanent installation and you shouldn't either. Looking around online, replacement controllers are available, that isn't going to happen with any of the other pumps in this price range. I can't speak to longevity, but based on my reading these are either great or a dud, and it should be known soon enough, I'll update my review if I have any issues. The only cons I see are that the barbed adapters aren't the best quality I've run across, but far from the worst, and because they're well fitting with standard 3/4 vinyl and silicone tubing they don't need to be wildly torqued down with a hose clamp and I don't foresee any issues. The instructions are in the second half of the manual, and convey enough to understand how everything works if you are a competent English reader, but they're also very sparse on extra information you might want, like o-ring size, etc. I highly recommend this pump, even if it only lasted a year I would consider it an excellent value at this price point, but hopefully I'll get much more life than that.

First time water feature builder, and I saw good reports on this pump and it behaving as well as more expensive pumps with fewer features. It hooked up easily and pushed water through my 2" tubing quickly and silently. Honestly, I can't tell that it's running except for all the water it spits out. The controller is easy to operate, but it lacks an off switch. You can pause it for 10 min, but not shut it off completely without unplugging it. The only "issues" I found were connecting the tubing to the pump was a bit more difficult due to the small outlet size. I could have used 1.5" tubing, but would have seen flow reduced as a result. Also, you can only adjust flow down to 30% of max, but this can be worked around by controlling flow with a ball valve. I could have bought a smaller size for my 18" x 25' x 6" deep waterfall/stream. The lowest speed flows a great amount of water through the stream with a waterfall at the head and 3 more cascades before getting to the water reservoir. Lastly, my only other complaint is the length of the power cable between the controller and the pump. I was able to find extensions for it, but there weren't many choices. I'm not sorry I bought it and it has been running flawlessly for 2 weeks now.

I purchased another pump from Amazon about five years ago. It was the best pump I ever purchased. It let me forget that there was a pump running all the time. Unfortunately, be it due to our very hard (actual EPA rating) water or time, it started working sporadically, costing me two of my mature (6+-inch) tropicals. I forgot what the other was, but in my experience shark cats are tolerant of everything except stagnant or insufficiently moving water. I guess their similarity to sharks goes beyond their appearance. I returned to Amazon for the replacement, knowing that I could find a far better variety than any local supplier. I was not disappointed. This pump is super quiet. I attribute this to it being a DC rather than AC motor. I can vary the flow. This is important, because I use a homemade sump system, and this allows me to choose whether to push or pull the flow. What I mean is that I can make it return to the main tank a little faster than gravity pulls it out, and therefore have slightly more water flowing through the system overall than a fixed-rate system. Mine is a freshwater sump system. The main tank is a 72-gallon pre-drilled bow. The sump is a 15-gallon tank with a ten-gallon tank that serves as the physical and biological filtration section. This leaves a 5-gallon chemical filtration refugium space where the pump sits and returns the water back to the main tank return port that is about four feet above, flowing through about five feet of 1-inch tubing. I am not nearly as much of a techie as this may make me seem, so do not ask me about the physics. I am a tinkerer and experimenter who is never satisfied with the status quo or conventional solutions. On my list of projects is to build a(nother) stand which fits better aesthetically with my Bride's excellent décor. The way this pump functions makes me all the more eager to get it done.

Excelente producto! La bomba prácticamente no hace ruido! Trabaja a la perfección y me agrada que traea bastantes aditamentos y repuestos! Excelente producto.

Great pump for the money

No hace ruido

Excelente producto muy recomendable

Running for about a week. This pump is powerful and I am running it with my 180 gallon pumping up 6 feet of vertical head. Pretty quiet, easy to adjust flow rate, no more frustration trying to turn the valve bit by bit... Fast shipping!
