Jebao DCP return pump?

So I've been using the DCP-18000 for about a day and a half now, some thoughts on it for those looking for a basement pump. If your tank has any size to it I would keep looking.
Full disclosure, this is a FW system. I have a 1200 gal pond in my basement, then a 150 gal on the first floor. Pond is more or less acting as a large sump for the 150. Pump is moving water up about 5', over 5', then finally up 6' where it is split into two returns. The pump's largest fitting is a 1.5" slip, so I used that then up sized it to 2" for the return pipe.
I don't think it is moving as much water as I had originally thought. I had set the pond to 78*, after about 12 hours the 150 gal was only at 76*. I bumped the pond up to 80*, tank only rose to 77* overnight.
I know this isn't a great indicator of flow, however prior to this I was using a hammerhead (which also fed several other things). Water always was the same exact temp, overflows also had trouble keeping up unless the valves were nearly fully open. Now the overflow is silent, which I'm happy about but it indicates to me not much water is flowing through them.
So those are my thoughts on the bigger pump. It is a solid feeling pump, the controller is even nicer than the smaller units and price isn't bad, but I don't think it'll handle anywhere near the head they claim.

what is the flow rate claim on the 18000. There is no way you can compare it to the 6800 gph hammer ,I have a hammerhead pump and and its drop off curve for head pressure is much less any any DC PUMP.. You are 11 horizontal feet with atleast 3 elbows and a t... I Would switch all bents to spa flex and eliminate the T and change it to a long sweeping sanitary T They have less head loss...
so with the 2 t s and 1 elbow your simulated head height would be equal to 15 feet ... That should put a 4000gph dc pump to maybe 1000gph.... Off the top of my head without actually figuring it.. So yes for you it might not be the best pump...... They losses are high with head pressure
Thanks for sharing... :beer:

18000 liters per hour is roughly 4755 gph. I knew the jebao wouldn't move anywhere near the water the hammerhead does, I didn't need it to as the hammerhead was powering several things, the 150 gal included. This pump is running the 150 gal exclusively.
I haven't seen spa flex in 2" otherwise I may give it a go, though I did use the sweeping 90s on all of them. I can't remember what kind the T is as it is behind the tank. Looking at the 18000 flow chart, at three meters, about 10', it's still pumping about 1800 gph, they claim. I've been estimating about 15' of head as well, I knew there would be a significant drop off from where the flow chart left off, but I think it was bigger than expected.
I'm probably just going to separate the tank from the pond, I have a couple of the dcp-10000 I can use on it with an old 40 breeder. I do like these pumps, even the 18000 is dead silent, I just don't think they move the water they are supposed to.

Jebao DCP return pump?
I received my 6500 last night and hard plumbed it in. It's in my basement pushing I'd say around 9' vertical and horizontal through 3/4. First impressions were that I couldn't believe it was on and pumping as it is so completely silent. To the poster who says he hears it throughout his entire house and has had it replaced, maybe check your plumbing or something, as this thing is dead silent. It barely can be felt 5 inches above on the plumbing, and like others have said, I have to put my ear to the sump to hear it. My mj1200 or whatever comes with the brs duel reactor is much louder, and it's quiet too. I have the 6500 set to about 78% and it has already exceeded my expectations. My basement fish room is a work in progress so excuse the mess.

How is that 6500 working for you being in the basement? I am fixing to build a new manifold to run 2 reactors my algae scrubber and my tank on my reefer 250. If my current pump (Reef Octopus VarioS-6) can't push the water needed I'm looking to replace it with either the DCP6500 or 8000.
Thanks!

So on these new dcp pumps it looks like they come with adapters to hook into your plumbing. So if you have 1.5" pvc for your return can you hook a 10k, 15k, and 18k all right into it? Just curious how easy it'll be to switch pumps around.
I was going to get a 15,000 for my skimmer and return and buy a 3rd just for a backup so they're all the same pump but a 15,000 is huge overkill for my return.

I see it listed at a Canadian retailer now. Looks like supplies have finally reached North America.

When it gets warmer out I am planning on setting up a straight vertical 2" pipe and test flow rates at various heights and build up to shutoff. The DCP 15000 and 18000 will be apart of it.
Which I just got both in and will try on my skimmer! Will compare flow rate, watts drawn, and air draw vs. a waveline dc 12000 apex ready pump.
Looks like there's also a dcp 20000 according to the manual.
I'm extremely thrilled these came with pvc slip adapters. That's awesome.

I'm not sure China understands inches. lol
I'm trying to get to 1" and looks like the 1.5" included fitting is 1.5" on the outside but seems slightly bigger.
1 1/2" coupler doesn't fit on the 1 1/2" slip fitting included. But a 1 1/4" bushing fits inside.
So, that lines up with standard schedule 40 size for 1 1/4" pvc with outside diameter around 1.6"
So weird....

It's pretty awesome even if it's max flow or head isn't 100% accurate.
I find it quieter then the waveline dc12000 when I first ran it but the waveline did quiet down a lot over a few weeks to being almost silent at 100%.
I'm impressed it can go up in 1% increments from 30% to 100%. And I really like it gives how many watts are being pulled by the pump. Killawatt is higher from the wall.
Watts sent to pump at 30%
1% increments
Here's a quick first look and going to run the pump at 100% to get a good running average so these numbers will most likely change a bit over time but not by very much.
