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.

Works great as intended

Some of the components feel a little flimsy and roughly manufactured. However everything fits together well. It is very quiet. And the variatable speeds save electricity. The controller is simple enough to use. It has been in use for almost a year and is working very well. I was glad I purchased it and it has served me well. No leaks at all. Comes with glue unions which I used my regular PVC glue and primer on. Be careful of sizing this pump to your tank. The GPH rating is generous and does not factor in feet of head (height the pump has to send the water) the flow rates go down the higher it goes. All this to say this was perfect for my 100 gallon tank + 40 gallon sump. Update: 2 years running. Had a slight leak so I took it apart for a repair. The main body O-Ring failed and was leaking. Not the worst after two years but O-Rings should last a bit longer. I happen to be a commercial water valve technician so I had a replacement on hand. Upon complete take down and clean of all motor components it wasn’t over all in like new condition. After replacing the o-rings it worked like the day I first plugged it in. If I were you I would highly recommend contacting the seller who is very friendly and responsive and ask to buy a spare o-ring kit. And get some o-ring lube. In case you have the same issue. I personally will be buying a second pump to have on hand. Return pumps die or leak all the time it is what they do. If you have a spare that is the same one you can drop in the new one and get parts for the old one. Fish can’t wait for 2-day shipping. I still give this a 5-star. You can buy 5 of these for the price of the “name brand” dc pumps. If your buying this for the first time buy one more than you need. You will always be prepared for an emergency. I’ve seen other reviews about some mfg issues. They don’t have great quality control but they make up for it in customer support. And for the guy who put thread tape on an o-ring union 🤦🏼‍♂️. C’mon man! The o-ring in the union does the sealing not the threads. Don’t leave one star reviews because you don’t know basic plumbing. Guys o-rings fail. Have spares! And check your equipment often.

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.

Just received this pump as a replacement for a Mag 18. Both have similar performance curves, but this one promised much lower electrical consumption, which is my main reason for switching. Positives: Very well packaged, multiple boxes, and layers to get through, pump and parts neatly organized. Pretty simple connections for the 3 main components - pump, controller, and DC converter. Upon installation, pump also is quiet, virtually no audible hum. Negatives: Manual sorely lacking, clearly it was a translated document done literally so there are a lot of very strange phrases in it. Bigger issue is that while the control unit only has 3 unlabeled buttons, an up arrow, a down arrow, and a pause button, the manual references the "FEED" button for instance. The unit comes with a bunch of connectors, none of which were sized for my existing tubing which is standard 3/4" tubing. There are both barbed connectors and what looks like slip connectors for pvc, but they are some sort of plastic, and I don't know if they are compatible with PVC. I was unable to find a connector sized to any of the various piping I have in my aquarium closet to allow using a foam prefilter for this pump, so I left the coarse screen. This screen is not fine enough from preventing fry from entering it - often my cichlid fry end up in the sump. Other: The unit is surprisingly light compared to the Mag 18, probably about 1/2 the mass. Not sure if this is good or bad however. Overall, the unit seems ok, obviously can't make any judgements on longevity since it was installed yesterday.

I bought my first Jebao DCP5000 from a pet store near me that's, now closed, 4 years ago (give or take). I used it for half that time submerged and half that time as an inline pump to a canister filter on a 125g tank. It's super quiet. It's powerful. I have my tank hard plumbed most of the way with 1 inch pipe and it still shoots water out of a full opening AND a makeshift spray bar to agitate the surface water. It pulls water out of the tank aprox. 7 ft of pipe and 1 inch flex line. And pushes it up aprox. 6 ft back into the tank. If the current is too strong its got a control that allows you to tone down the flow without adding or using ball valves. When my old one started leaking through the case after I did maintenance on the canister I bought a new one just like it so I could "plug and play". Unfortunately, the new one came and it was leaking through the case as soon as I installed it. Went back on here and did a ticket for a replacement and the new puml came in super fast wraped up like fort knox. I took it out plugged it in and viola! Tank up and running again. No hassles. No issues with customer service. Convenient. This thing beats the expensive pumps all day long, I hope they don't change them for the worse. I never cleaned my old pump, opened it today to find calcium and mineral build up (i live in Florida, the water is liquid rock). Im going to scrub my old Jebao down and check the gasket ring, that might be all thats the matter with it. If its not it and theres a crack somewhere in the front thats causing the leak I can still use it as a submersible pump. It still running like a champ and still super quiet after four yrs of hard use. My only true complaint is that I wish they would send extra gasket rings or make them easily accessible. But I haven't searched for them.

Purchased this pump for a saltwater mixing station. I chose this one because it seemed to be very positively reviewed and at a low price. Worked fine out of the box. Shortly after installation I noticed that the controller stopped working entirely. Several months in it stopped working entirely. I have seen many other posts claiming the same thing. I reached out to the manufacturer via their contact information on the product box and have not received a response. I will be out a lot of money on this as the system was designed with the pump dimensions in mind and will have to reconfigure the entire thing.
