What is the best silent, high flow closed loop pump?

plaz · 10/23/2004, 10:41 AM

Adding a closed loop on a 200+ gallon tank. 4 1" bulkheads are in the bottom of tank. Need a high flow SILENT pump. Any recommendations (looking at blueline velocity or ampmaster 3000 - but maybe something else is better since there would be 0 head?)?

the velocity Titanium are the only "silent" pumps I know of... I have a T4 runing on my tank right now and you can not hear it.

These pumps do put out alot of heat into your system.

benonmsn · 10/23/2004, 11:24 AM

yes, tons of heat, for example. on my system, i have a 75 gal, a 20 gal, and about 40 gals in the sump. i use 2velocity t4's and one mag 9.5. at night, with no lights on, my chillerstill turns on. the system runs about 89f with no lights.... it is such a quiet pump but seriously runs hot. obly about 1200gph as well. u would want the amp master 3k or one of the sequence models, the t4 is not enopugh flow for your tank.

Second the Sequence pumps. Form what I understand they are one of the better-closed loop pumps around.

I have not used the sequence pumps, but I have heard great things about them. You could also consider multiple Iwakis. I use the 30RLXT and it is pretty quiet as everything under the 40 series doesn't have a fan, but it may transfer some heat.

viggen · 10/23/2004, 02:47 PM

I also have the velocity T4's 1 on my 90G reef & presently 1 on my 240g fo. I am setting up a 300g & I plan on using a T4 for recirc & 1 for closed loop through oceanclear.

FWIW, I have a chiller on both tanks

It sounds like most people like the sequence pump. Custom Aquatic has the WP-MTDART on sale for $179 at -http://www.customaquatic.com/customaquatic/brandcategory.asp?offset=96&brandid=MT&catID=wp.

It looks like a good pump and is already fitted for saltwater. What do you guys think?

Also, I'm not familiar with the oceanclear - is that a pump, filter or both?

Thanks for everyone's help!

GRI 520, Pressure/Flow/Noise... Balanced pump.

adamsreeftank · 10/23/2004, 03:23 PM

I replaced both my Iwaki 55 and 70 with two Sequence Darts.

The Darts are much quieter and have more flow. They are not pressure rated like the Iwakis, but for returns and loops, they are great.

I started with the Iwaki 55 when I was running through two large canister filters on a FW tank.

The only totaly silent pump I have used is the old style QuietOne, which is truly silent. It also puts some heat into the tank. I may use one to run a loop from the sump to my chiller. It only puts out about 500 gph and is not pressure rated.

plaz · 10/23/2004, 03:44 PM

I had one of the old quiet ones and loved it - until it died. I replaced it with the new quiet one 4000HH and I hate it - it is very noisy!

So, the Sequence Dart seems to be recommended over the ampmaster 3000? On sale it is cheaper - so, that is great!

Those of you who have the Dart - is it really, really quiet (like I won't even hear it in the cabinet?)? The sump is behind a wall. The tank and cabinet sit about a foot away from my desk (so I really need it to be silent).

jsbzmcdaniel · 10/23/2004, 04:56 PM

I am running the Dart on my OM closed loop and the pump is silent. I had to put my hand on it to make sure it was running

.

plaz · 10/23/2004, 05:15 PM

Great, Thanks!

PS Does OM stand for ocean motion wavemaker?

benonmsn · 10/23/2004, 06:10 PM

oceanclear is a canister filter

AcroSteve · 10/26/2004, 02:09 PM

Sequence Dart!

jda · 10/26/2004, 02:35 PM

I have a sequence dart and an ampmaster 3000. Both are quiet and work well. I would not switch one for the other, they are both good.

Mr.Lloyd · 10/26/2004, 04:38 PM

I have 3 ampmaster 3000's inside my cabinet and I do not notice the noise.Maybe after 3 kids making it to college nothing sounds loud.Dolphin makes an anti vibration pad to place under the pumps.It works.

FishF00d · 10/26/2004, 05:32 PM

so would it be worth it to go up one step on the reefflo from the dart to the barracuda?

AcroSteve · 10/27/2004, 08:09 AM

I do not think the barracuda has the reputation the dart has.

3twenty5 · 10/27/2004, 09:00 AM

My Mag12 is very quiet

kpk · 10/28/2004, 12:57 AM

I just got my barracuda plumbed and running and it is awesome. Tons of flow in my 110g. It is plumbed over the top, too

Rendos · 10/28/2004, 07:09 AM

Waterways Iron Might 2400 GPH pump on my closed loop. It is absolutely silent and cool to the touch.

Great pump, but I have to disagree on the noise part. It's a lot quieter than a large Iwaki or LG, but still much noisier than Sequence pumps.

The single GRI 520 on our 205 is noisier than the combination of 2 sequence pumps on our 700. And one of those Sequences is a 1000-series pushing 5200gph.

Regards,

mattls · 10/28/2004, 12:34 PM

I have an ampmaster 2700 on my new 120aga closed loop setup under my tank and it seems to work great so far. I don't even hear it and I don't even have the doors on my stand yet. I screwed it down nice and tight and no noise or vibration.

plaz · 10/28/2004, 07:10 PM

Thanks to everyone! I have decided to go with the Sequence Dart and to add a Dolphin vibration pad if needed.

The Dart has a 2" inlet. For those with that unit (or similar) will one 1.5" and one 1" inlet with strainers (both from bottom of tank) fed into a 2" pipe provide enough flow? I want to make sure I don't cut down the flow as much as possible - also don't want too much suction to pull in critters through the strainers. I have another 1.5" bulkhead but it is about 4' away from the others (and I thought it might be better as an outlet).
