Looking for some recommendations for CLS pumps. Pumps that can handle between 10000 l/hr - 20000 l/hr, are relatively quite, reliable, and the big catch affordable. I’ve looked at pumps by manufactures like Gorman Rupp, Robot and ABS, but they are a bit pricey and overkill for my requirements.

Hi everyone
Also looking for some recommendations for a pump i can use for my closed loop sytem. Most importantly is reliability, flow rate and noise. Obviously price as well.
I'm wary to use anything unreliable as this could lead to my 1400L tank pumping out onto the floor of my appartment.

The flow rate i would like is around 14000L/h to 24000L/h.

Anyone know if 2 reef octopus 7000L/h blaster pumps would work as closed loop pumps??

I was told that a Polario would not work.... what does a Red Dragon pump cost and where culd i get one :)

Thanks....

I just found that the Hailea pumps are quite heavy on electricity. The 6550 which does 5580LPH is 200W. The RO pumps (the new RO blaster pumps) are very nice and the 7000LPH is only 88Watts

Hi Marlin. Try out the Haliea range. I find those pumps to be much more reliable than the Reef Octopus pumps.

The RO blaster pumps are much better than the RO otp pump.

regarding Haliea and OTP- ill rather go Haliea it lasts longer(ditto @ mekaeel)

The Bubble Blaster is a very very neat pump and the new impellers will last much longer than the old once

i added one to my closed loop system yester day and it works very nice

MD pumps ar also very decant closed loop pumps but munches electricity :p
The ESPA pumps will also work for a marine setup and it will work great for a closed loop setup

mmm OR6500 110w for 6500 lt. very reliable but a little on the small size if you wanting massive flow. still good price compared to the amount of flow and wattage..

I'm getting a pump for my CLS that has 5800l/ph at 90W power usage. Will try and get the name if you want. ;)

It also costs about R1200. Not sure what the RO pump costs though...

External of course, and has a 25mm pipe outlet for good pipe size.

Are there any other pumps that are stronger than the RO blaster (about 10,000L/h or more), can be used for a CLS and are very reliable?

My issue is that i have designed the returns and the feed for my closed loop in the base of my tank similar to Paul Whitby's "tank of the month of March 2007 in Reef Central". This design worked extremely well for him as it allowed for detritus removal from the rock work as well of continuous suspension of ditritus in the water column. The only problem is that it is a risky positioning of feeds and returns thus pump must be one that does not fail!

So a strong reliable pump is essential

There are yes. My LFS paid about R1200 for a 15000l/h pump. It's more an industrial pump, so the catch to it is the noise factor. If you want to place the pump in your display area, it would make a noise. This is the only reason I am not opting for this version, as I will have to drill a 30mm hole through the wall to have the pump outside.

I am having the same problem. I can go through the wall etc, but that just throws noise to somewhere else, and then if I must try and sleep and hear this pump will drive me bonkers...

So...

What I suggest you do is get two 6000 - 7000 l/ph pumps and connect both onto your CLS. This will work great, as the pressure will really give you good flow. You can build a total closed loop, so they actually work agains each other. Just make sure to add enough outlets though, or you might damage the pumps. ;)

Sounds cool!

Thinking in the line of 2 RO Blasters 7000L/h connected to the closed loop.

I have 2 large outlets and one (larger than both) inlet. this was designed with plumbing large enough to support a 20000L pump so it should work.

Just hope that the RO blasters are sufficient and reliable. They havent been in use here in SA for a long enough time for people to rate their reliability over the longer term. (IMO)

Marlin i cant really comment on the pumps other than the OR6500 as i have no on hand experience with them, but from what i have heard the iwaki's are excellent pumps and really deliver for the wattage involved.. the RO blaster pump is a very nice pump and id love to try one out before i offer any comment.. guys to talk to about iwaki would be Punk and Submariner.. they uitalise these pumps for CLS

I'm considering a Swimming pool pump for my next system - plumbed outside in a wendy house where my sump etc will be and the wendy house will be lined with that siver stuff to keep temp down and have a aircon built in to give constant temp. Not 100% decided on this but considering.
