Head loss on Jebao DC Series Pumps???

fishbox · 11/21/2015, 06:45 AM

I can't seem to find a chart or info on the head loss on these pumps. I'm looking to get around 300GPH @ 4.5' but don't know if I should go with the DC-3000 or DC-6000. Any one have head loss info?

I think there is a flow curve on the fish street site.

fishbox · 11/21/2015, 07:32 AM

I checked there but don't see it. Maybe because I'm using my phone as my pc is screwy right now. Can someone post it here?

They perform pretty poorly against pressure.

Yeah looks like I might be better off going with an Eheim or somethig

The newer DCS pumps have a much better curve and they use less power. I just got a DCS-9000 and it is great.

I didn't know about the DCS series. I'll look into those. Any suggestions as to which one will give me around 300GPH @ 4.5'. I see your image too well on my phone.

According to the chart, the DCS-3000 will give you ~400gph. Real world values may be lower.

I wonder if that's with the settings on high or low. I'd rather it be low this way I have room to upgrade and provide more flow needed

I run a 6000 pushing 4.5ft and it does just fine - I run it on 3/6

Roughly how much GPH are you getting at that height

karimwassef · 11/21/2015, 03:17 PM

I run the DCT 15000

I have ~ 4 ft head (1.2 m) that shows at about 11,000 L/h ~ 2900 gph based on the chart.

That's about what I get.

If you have ~ 4.5ft head (1.4 m) and want 300 gph (1,100 L/h), the 4000 should work.

Since they're digital and DC, you can also dial in the flow experimentally (hold a container bucket at the output level and count the seconds to fill).

Thanks for the tips

I'd say 700ish, i had replaced a Mag 9.

Yeah that's a oil too much for my need. I'll try the 4000

ucdcrew · 11/21/2015, 09:32 PM

Mine's the old school one too so probably a good idea.

fishbox · 11/22/2015, 07:42 AM

How quiet are these? This tank is in my bedroom lol

Ron Reefman · 11/22/2015, 07:56 AM

I have 2 of the original DC12000 pumps on my 400g system. One is in the sump and the other is external for a Closed Loop. Neither one makes any. The external one is barely warm to the touch while running at 4 of 6 and pushing a 6' head to an Oceans Motion system. The in supm pushes water out the back of my house to a 1hp chiller and back into the bottom of the 180g tank. Total run is about 20 feet and 30" head.

laga77 · 11/22/2015, 08:01 AM

I am setting up my third tank that will have Jebao DC12000 or 15000, The other two have worked great and push plenty of water at a 5` head. One is 2 years old and the other is 1 year. Both are in my TV room and very quiet.

Quietest pumps I've ever had
