DC12000 with 9ft head preassure

[Horace]

Hey folks,

I have an in the box Jebao DC12000 (the blue one), that I was originally hoping would meet the flow needs of my return pump with it being in my basement with about a 9ft run to the tank. I have read recently that these DC pumps do not handle the head pressure well, which would contradict the statements on the box regarding flow to head pressure graph. Can anyone share some real world experience with this pump and this level of head?

I really think the dc can't handle that much presure.

This is not helpful . Do you have this pump? Why do you think this?

[FullBoreReefer]

I have had this pump since it came out, it runs externally on my mix station in my garage. It pumps vertically 7ft and horizontally about 35ft and then back down 7ft to my sump. It still pushes a lot of water. All my piping is 3/4".

The pumps that Jebao stole the design from cannot handle the pressure.

Get a Fluval - it will end up being nearly the same wattage in real use and will last for a decade or more, can handle the head pressure if you get the correct one and you don't have to support a company that steals from other legit companies.

Assuming you don't plan on returning it (and even if you did a little water won't hurt.. just dry it right out).
Attach it to a 10ft PVC pipe, dump it in a 5G bucket of water and see if it will pump water out the top..
If it did you answered your own question with real world experience and not opinions like what you are getting from some here..

9' up, a few elbows and some pipe friction. Plan on 12 or 13 feet of head. The coralvue that was the exact same pump would barely trickle at 10', wattage was more than advertised and submerged heat was what you would expect from a pump over 140W. It changed water until it failed within a year. If you are expecting that you will be the only one with good results at head from a DC pump, then you will be disappointed - you can believe the many, many posts from actual users, or the label from a company whose whole business model is based on lying to people.

BTW - 7 foot up and 7 foot back down is zero net head...

Where is somebody going to return a Jebao?

Hmmm, vertical is vertical where I'm from, still has to pump water up before it goes down, but I'm not a gravitational water pipe pumping expert. Plus my 4-90s and two ball valves, either way it still moves a lot of water in my case.

Guess I'm the lucky one after many many years of service...i guess buy something other than Jebao, it'll leave me a chance to buy more, JK Haha.

By the way...

1 - dc12000
1 - dct12000
2 - dct8000
1 - dct6000

All in current operation and working great...but again, I must be lucky...

To the company where it was purchased?
Assuming its still in the return period..

The more and more I think about a basement install, the more I think I may not do it. As much as I love the idea of putting my sump and gear in the basement, the more complicated it gets. I think I may just have to be very intentional about making my setup as quiet as possible (already have BeanAnimal drain setup in the works). I am hoping that between the Vertex Skimmer, DC12000 pump, BeanAnimal drains, that it should be pretty quiet. I suppose in worst case I can always move the sump to the basement later, though that will be a major PITA to do after the fact.

You will likely like the basement sump better. There are dozens of reliable and efficient pumps to handle the head, just none of them are DC - no big deal since you would not have saved any electricity anyway. Just get a Laguna or Fluval and don't think about a return pump for a decade like many folks do.

The Fluval SP6 or the Laguna 4280??

Both are pretty large.

[Horace]

I rand across this beast....Aquascape AquaForce 5200 supposedly does 4000gph at 10ft of head. Even the 3200 does 3600gph at 10'. That seems like that would do the trick for sure lol. Those pumps use 215w and 360w though.

[jda]

I have a Laguna 2900 that does basement with 9' ceilings straight up to my tank on the second floor with a few bends at the end - probably 900-1000 GPH and about all that the dual overflows on the AGA Megaflow can handle. That pump is running right now at 111 watts or real power.

I like submersibles since 11 months of the year, the extra heat that the give off is a blessing.

Laguna and Fluval are the same block and pump, but Fluval has ceramic bearings that most suppose will last longer in saltwater. They are probably right, but with many, many years of service on my Lagunas, the nylon bearings are still just fine.

If you are wanting to send 215 to 360 watts, get an Iwaki, Panworld or GenX pump and buy a pump for a few decades and will actually do what they are rated for (if not more). I have been doing this for a long time and I had never heard for AquaForce 5200.

[Horace]

Yeah so I definitely underestimated my head. My total head without even considering connections is about 16ft. The ceiling is 10ft (9ft +1ft joists) + 42" stand + 24" tank. I think putting the sump on a stand is a must

Sump on a stand is good for a lot of things, but it will help a lot with head too. I like to be able to siphon gunk out of the sump.

[oseymour]

How much flow are you expecting to get to the display?

I have a Vectra M1 which is rated at 2,000 gph and at about 7 feet I get a little over 600gph as measured by the bucket test and the Neptune flow meter.

The Vectra is a better built pump than the Jebao so expect about the same losses. I'm using 3/4 pipe.

You'll need to use the largest pipe possible and don't expect more than a couple hundred gallons per hour of flow to the display and you'll have to run the pump at full which will make it more noisy and reduce it's useable life.

If I have critical life support in the sump I would not use the Jebao pump in the application you are proposing.

[Horace]

I have already concluded that the DC12000 is not likely going to cut it, so I am going to build a stand for the sump in the basement to shorten the head, and i am going to try out the Fluval SP6 to see if i get adequite flow. I am not relying on HUGE flow from my return pump, but i still would like 5-10x or so turnover if I can w/out getting a massive/power hungry pump.

[GQsmooth]

Deepwater Aquatics BLDC12 would work.

[McPuff]

You will not regret going with a basement sump. It is much nicer and easier than having the sump under the tank. So many more options. Find a pump that will do more than you need and you'll be happy.

Post #17...Showing a DCP-18000 pumping water up 29.5 feet...

Their literature states 9 meters (29.5 feet) max.. Real world test... it pumps to 9 meters (29.5 feet).. Things that make you go hmmmm..

[Horace]

Reefcentral, you have let me down for the first time.

I am hear to tell you that the DC10000 dominates the Fluval SP6, and not by just a little.

I hooked up a test with the plumbing nearly identical to how it will look with my install, with a 12.5ft head, with 3 90 elbows and a 8ft horizontal run.

The SP6 put out a measly ~330 gph

the DC10000 put out ~550gph

So not only did you lead me think DC10000 had no chance, but you had me buy a pump that put out 40% less water.

The bad news is NEITHER DAMN PUMP IS GOOD ENOUGH! GRRRRRRRRRRRRRR

[Horace]

For the doubters....

So now what? I think either I go with the DC 18000 or I need to go with ?!?!?

Remember trouble shooting problems is a headache for basement sumps.
