Need Your Help with Pumps!

[Edv]

There is my problem I have a return pump, other one for
my chiller and yet another for my reactor.

I was thinking to get one pump and tee it off one
side will be a return and the other side will go
to the chiller and then go to my reactor. Is this to much?

The pump I was looking into a Waveline DC 6000
or DC 10000 .. Why these pumps I like it because
you can give more power or less power by
pressing a button that a good thing.

Question I have should I leave well alone go with one pump?
Just trying to make room in my sump.

Your input is appreciated thank you.

It will work, just make sure to have valves to control the flow.

 

[Edv]

YES would definitely have them.

Thanks

For reference Edv, I was using a Jebao DCT 6000 for my large pellet reactor. IMO, all the DC pumps flow rates are at zero head pressure so the expected outcome is less then what you think that you will be getting.
When my reactor had 1500 ml of pellets, it had to be on the highest setting which I felt was no where near 1585 gph.
I also use a Jebao DC 12000 for a return tee'd to a same level tank and the other side to a tank on the next level. It works but minimal flow combined which I'm fine with so my point is that you should go with a much bigger DC pump if your going to tee off to a tank, chiller & reactor. Not sure what your looking for in return flow but most chiller are restrictive. You should be able to tell with whatever pump you are using now.

 

[Edv]

Wow I didn't know about that..

This is what I have now 60 gl.
My return pump is a mag 7
For the chiller I have a powerhead MJ900
for my reactor 150 has a small output powerhead.
My other reactor as it's own built in pump (CAD Light)
My skimmer is R6i

I was thinking about a 6000 would you think the 9000 is
would be better or even a 12000?

Wow, you must have a small chiller. In my old system I had to use a Mag7 to feed a 1/4hp chiller.
I would go with the DC 9000, this way you can always turn down the pump.

 

[Edv]

1/10hp chiller not to bad. As for the mag 7, I was using a mag 9.5 I use getting a lot of noise from the over flow box that was driving me mad. with the 7 you don't hear a drop at all you swear that it's not even running. Or leave well alone!

Question I was looking at the Reef Octopus RODC 5500
is states that as a 13ft head pressure. But cost a boat load.
Should I don't believe in that?

In your opinion how good is the Jebao DCT 6000 or 9000.
Cost a whole lot less then all others

 

[cypher]

I'm running the RODC 5500S Pump on my 300 gallon tank as a return pump and I'm love it

 

[Edv]

Question for cypher

How is the noise of that pump & do you have it tee off?

What are the is setting 5500s
1 2 3 4 5 6full power

Any dislikes about it?

 

[Edv]

Just wanted to say THANK YOU for all your inputs!

 

[cypher]

The Pump is quiet I do have it tee off for the power I have it on 2 for now because I run 2 mp60 if you want look on my page to see how I setup it up

 

[pecan2phat]

With the DCT 6000, it's max head pressure is 12' 5" but you get zero flow with that kind of head pressure so it's very misleading. A better example is looking at 1.75 meters (5.5'), a DCT 6000 losses half of it's overall flow so the 6000 liters (1585 gph) becomes 3000 liters (792 gph). Head pressure is not always height either. It could be a combination of 90 degree elbows and smaller sized tubing.
I've only had the DCT 6000 for 3 months and the DC 12000 for about a year. DCT replaced the DC models that are 4000 lph and above. They are supposed to be a little better in max head pressure and controller is suppose to house some electronics that use to be in the DC pump. Also went from 6 speeds to 10. So if your asking me how good they are, I can only tell you that they are still pumping with no hiccups. But I will say that the Jebao line is a cheaper quality material and build then say the Reef Octopus line and I would not run Jebao DC pumps externally, they always leak.

[Edv]

Since most DC pumps lack a good head pressure
I'll be definitely going with a 12000 or 8000.

Would 12000 be over kill?

I have a new question is the Jebao (blue) is the older one to the jecod dct?

Thanks
Ed

 

[pecan2phat]

Ed,
DCT (gray) is the newer one.
Look at it this way, if all your trying to do is replicate the flow for the Mag7, MJ-900 & small powerhead, then the DCT 8000 should be fine. I used the DC 12000 to replace a Water Blaster 10000 and while it works, the DC 12000 only has about 70~80% of the flow the WB-10000 had. Also your not pumping up one story like I am.

 

[Edv]

New question how good are these DC pumps can it holds back pressure?
The last thing you want is it pop !

The highest it will be going is 4 1/2ft for the return.
For the other side I was thinking of putting 2 tee
one before the chiller an another after the chiller
not going to use hard line just tubing give more
flex in small space.

 

[Edv]

Is the DCT better performing the the old type
since you have them..

 

[pecan2phat]

Not sure exactly what you mean about back pressure but no pump should "pop" their o-ring seal from back flow.
You should look into manifolds. Do something like a 1" PVC manifold that has a 3/4" ball valve going to the return flow and a couple of 1/2" ball valves to feed your other equipment.
Something that looks like this:

[pecan2phat]

Based on what the manufacturer states, I would go with the DCT when available. They state that electronics that were previously in the pump (DC series) are now housed in the controller and the controller has a few more speeds then previous.
On the Jebao line, the DCT series start at 4000 lph.

 

[Edv]

Sorry what I meant to say when you turn off a valve the the pump it running
it creates back pressure some pumps could hold that pressure. I was just asking
if it can hold the pressure that it produces..

8000 here I come or if I can get a 12000 on sale or cheaper I'll get that then.
