Having room is nice, and I am very happy now, knowing I have a spare, ready to go, even if I am away, I could talk someone through the change, pretty easy.
thank for share, I am setting a sump at Basement of my house. My Display tank( 200 * 750 *600 cm) in Ground Floor, The distance from sump to main tank about 7-8 meter. What Kind of return pump I should use? Thank so much ( I am thinking about Jebao DCP 20000 )
I would get the biggest pump you can in the family. If you run it at less power it will last longer as well. There is definitely a step up in performance from the 24v to the 36v, so make sure you go with a 36v pump.
I want to send you a video of this guy in South Africa. He uses the same pump 4 of them . He has 18,000 gallons how is this possible to filter that much water.
Hi, could you tell me the exact size of the pump? The return pump compartment in my sump is only 15 centimeters wide and I don't know if it will fit in. I saw in you video that the part where you connect the pipe is a little bit wider than the pump, do you know the total wide? Thank you!!!
The display is 125g, with a 2" return, that splits to a pairs of inlets in the tank. Drain line is 1 1/2, with a gate valve that limits it down to get siphon flow without slurping air
What size tank is this on? Also can I step it down to 3/4 inch out. I have a 180 gallon tank with 2 pipes both 3/4. Do you think I can run both pipes off 1 pump?
Anthony Murphy my display is 125, but up about 11 feet above the sump. You should be fine feeding 2 3/4" pipes, but I would use larger pipe off the pump and go to 3/4 only when you split. That will get you the most flow
I can't say, to be honest, I have attempted any kind of measurements to this detailed level. I don't believe the power to water flow relationship is a linear function, either way, and the system load (the plumbing, elevation change, cleanliness of the pipes, etc) all factor into it as well, probably in different ways. Of the multiple pumps I have tried on my return for my system, the DCP18000 is hands down the most capable, though.
They range from 30% to 100 of spec, so I would say the bottom on this would be around 5400l/h or about 1400gph with no head pressure. Any guess on what kind of head pressure it will see? That really is the key factor. The 18K is really pretty beefy, but if you are pushing water up 12 feet, like me, it is a great choice. I run mine at about 70% these days, which also feeds the fuge, frag tank and a reactor off the manifold.
I am currently working on an upgrade tank to a 300 . My sump will be in the room next to the tank. It will rise 3 feet and run horizontally 12 ft to the furthest point on one of them and about 8 feet on the second one. Should I have plenty of pump using the 18000? Thanks
James Freeman I would definitely think so. Your head pressure won't be anywhere close to mine. If you run 1.5 inch pipe you should be able to push a lot of water!!
Thanks for the reply I would have 3 90s in that configuration would that hurt my head pressure? I have never ran anything except tubing never pvc so I’m in unfamiliar territory. Thanks
The rule of thumb is 1 foot of head for each 90. So you are looking at 8, maybe 10 feet of head. What flow rate are you targeting? You may be able to find a flow vs head graph somewhere, but I suspect you will still have plenty of flow, even with the pump running low
Running 2 1800's on that will give you more than enough. Head pressure on one of those is 30 ft. (9.1 meters). You'll be able to run them at a lower power and still achieve the flow you are looking for. This saves you money on power, plus wear on the pump. Should one fail, you'll be able to push the other until you get a replacement assuming you don't have one on hand.
The names track their ratings in liters/ hour with no head pressure. So you should get 4k gph +/- with no load, running all out. Obviously, you will have a load in your system that will bring that number way down. I am in the basement, pushing the water up 10 feet to the first floor and believe I get 500 gph or more running at about 70% on the pump. I am a big fan of these DC pumps because you can dial them back and know you have some room to bump it up as the pump gets dirty and keep the same flow rate.
53% of the rated wattage of the 18000 model which is 130watts is 68.9watts, assuming 53% could also be rated as gph, gph would be about 2590 at 53%. That’s 48.8 gallons per percent. It takes the 18000 model 1.3 watts to move 48.8 gallons of water. Maximum watts x .01 = minimum watts Maximum gph x .01 = minimum gph DCP 18000 Maximum watts 130 Maximum gph 4887 Minimum watts 1.3 Minimum gph 48.8 DCP 15000 Maximum watts 105 Maximum gph 3963 Minimum watts 1.05 Minimum gph 39.6 DCP 18000 Maximum watts 130 Maximum gph 4887 Minimum watts 1.3 Minimum gph 48.8 .1w moves 3.75 gph 2.6 w moves 97.6 gph@2% .1w moves 3.75 gph DCP 15000 Maximum watts 105 Maximum gph 3963 Minimum watts 1.05 Minimum gph 39.6 2.1 w moves 79.2 gph@ 2% .1w moves 3.77 gph DCP 10000 Max w 80 Max gph 2642 Min watts .8 Min gph 26.42 1.6w moves 52.84 gph@2% .1w moves 3.3 gph DCP 8000 Max watts 65w Max gph 2113 Min w .65 Min gph 21.1 1.3w moves 42.2 gph@2% .1w moves 3.24 gph DCP 6500 Max w 55 Max gph 1710 Min w .55 Min gph 17.1 1.1w moves 34.2 gph@ 2% .1w moves 3.1 gph DCP 5000 Max w40 Max gph 1320 Min w .4 Min gph 13.2 1.2 w moves 39.6 gph at 3% .1w moves 3.3gph DCP 3000 Max w25 Max gph 845 Min w .25 Min gph 8.45 1w moves 33.8@ 4% .1w moves 3.38 gph The DCP 18000 is far superior if you take into account the length of hose used as the return or intake watt to watt against all other pumps. DCP 20000 Max w175 Max gph5283 Min w1.75 Min gph 52.81 It looks like it is even more efficient than the next step up. DCP 20000 105.66 3.5w .1w moves 3.01 gph DCP 18000 97.6 2.6w .1w moves 3.75 gph Maybe I am somehow wrong because it looks like the 15000 is slightly more efficient. I guess the length of the hose has something to do with it.
I have just recently purchased the DCP-20000, and although the pump curve is better than my Ecotech L1, I will tell you that the quality of the Jabao is mediocre at best. My L1 does fall short on GPH in my set-up as like most DC Drive Pumps they do not handle Head height very well, we will see where this takes me. Its a damn shame that there is no middle of the road high GPH pumps out there. You have these cheap Jabao pumps and you have Royal Exclusiv and Abyss..................But nothing in between. Good luck and wise move on the redundancy, one should ALWAYS have a back-up pump on hand
Ron, thanks for the feedback. I have so many other items on my "buy" list that I haven't even considered the "high end" pumps. With the cost here being less than half that of the Ecotech, it makes you think... I haven't run any of mine more then a few months, so far (tanks just got water in July), so I can't speak to longevity yet, but noise and flow are pretty great, from my view.
I am sure it will run just fine for you, I can tell you if your looking for more than 1000 GPH at a higher than 9' of total head height (Which most people cant calculate properly) the Vectra L1 although a REALLY WELL built pump isnt an option. now if Ecotech actually build a Vectra XL1 that moved 2000 GPH at 9' of head height I personally would be all over it even if it was $750.00. Essentially the difference is in the Volute and the Impeller. If you look at the higher end pumps Like Royal exclusiv and Abyss its a totally redesign Mag system...................really high end and I get the expense.................I just cant get myself to spend that kind of $. It isnt like I dont have it, I just dont see the value I guess. So time will tell, if this pump does not live long..............And it might or might not...................the replacement pump will be the either the Royal Exclusiv or the Abyzz.
Check me out, watching a video within a few days of publication! 😲 I’ve probably said before how much I like the Jebao pumps. With this one, if you wanted to push more water through the system, do you have the overflow capacity to handle it? I love your PVC forest - do you have additional valves that will allow more flow-through if you wanted it? And, is this 18000 running at 60-some watts at 65%-ish using less power than the 15000 was at 90%? Because if so, and there’s an additional economy in running a larger pump at lower settings, it’s even more $ in your pocket. My DCS 7000 return pump is set at 7, which I assume is 70%, and that’s what balances my system flow. And it’s only a 100W pump, so really cheap to run. I’ve been thinking lately that THIS is the kind of stuff that’s really hard to learn when you’re just starting out, and maybe why people like AIO or fully-designed and spec’d systems at the beginning. It has taken me years to reach the point where I’m reasonably confident in figuring this stuff out. And I still have those “oh sh*t” moments when I realize I’ve made a mistake. 🤯 Thanks for another enjoyable video, especially when we get to see a cat.
It's kind of like you are caught up! Still don't know how you watch so many vids, I see your comments everywhere... Yeah, very good point here on "extra" draining capacity in my plumbing. I have tons of excess drain capacity, actually. You are right on, with the larger pump comment. Yes, running the larger pump at lower rates is consuming less power while pushing more water! It's a win-win, and in the case of the 15k vs the 18k, the $20 difference in price should pay back over time in the electric bill. Maybe I should do that math and post it...
Lol, I decided to try and keep up on a daily basis as videos are published, then as time permits I watch prior ones. I no longer watch videos about Apex stuff, gyres, lighting, most unboxings (unless they’re from people who I know make videos I enjoy or equipment I’m interested in) or new build threads unless they seem really unusual or I think I can learn something from them. I only watch tank footage videos with no narration if they’re less than 5 minutes long and I’ve been following that tank’s progress. So as much as I want to watch every single video from the 3,467 people I subscribe to, I can’t. Unfortunately. 😁 Having said that, I make it a priority to sub and watch new channels because I remember how great it felt when I started, to have that support. CJ was my very first sub and I’ll always remember his support and encouragement. Haha, here I am, chatty as usual. 😊 That’s great that you have the flexibility to increase flow-through in your system and it’s a really good argument for hard plumbing and manifolds. Yikes, never thought I’d say that! And I’d certainly be interested in the power $ comparison between the two pumps you have used, and I think it would be really valuable info for anyone having to make a choice about a pump. And now it’s time for me to get moving so I can get out to the grocery store before we get hit with another huge dump of snow....😬
