Noise Pump Iwaki MD70

I bought a Iwaki MD70 to use as a return for my new 180 and the man this thing is loud. It has a fan attached to the end of the pump and even testing in the garage its very loud I can not imagine putting the thing in my dinning room. Does any know of a very quiet pump that will run about 1200gph?

I am now considering going to a mag 12 since I have used a mag 7 and the only noise is vibration.


Any ideas would be great!

The mag 18 I use is quiet. If you need 1200 gallons returned to your tank you may need a bigger mag, considering head loss.
 
Can the Eheim be used external?

What is the average flowrate going thru the sump?

zaozao I was looking at the Mag12 at 5' returns like 1120 and the Mag18 returns 1200gph which is close enough unless I am missing something.
 
Thanks I checked out he Eheim and the best flow rate I could get would be 700 or 750 gph which I dont think would be enough flow for a 180 gallon tank.

1262 is about 900 gph. It may be enough as a return pump as long as you have a close loop or other powerful powerheads for water circulation. I thought 8Ball had an Eheim pump as a return for his 180 but he has OceanMotion with a Sequence Dart pump for the water circulation. He's got a truly awesome set up.

Thanks I will ask 8Ball and find out.

The Iwaki I have has a fan on the back of the motor and it sounds like a helicopter taking off from the moment it was turned on until I turned it off. The sump was also loud but that was from so much water going through it.

The Reeflo pumps would be for a closed loop system more than a sump I would think.

UNO Series - Marlin, Wahoo & Tarpon is the ones I would look at for sump pumps.

The dart is not a sump pump, it is a "closed loop pump".

Wow Thanks!

The UNO pumps are great pumps for returns.. But really for a single 180 you don't need that much. It really comes down to personal preference though. You really only need enough water going through your sump/overflows to feed your skimmer and to keep your temp stable, Assuming that is that your heaters, fans or chiller are in your sump or fed by your sump.. If not then water flow matters even less.. Almost any standard size skimmer only really needs around 400 GPH or less.. Much less in most cases.. Tomoko is correct, I only use a Eheim 1260 for a return for my 180 works great for me.. My overflow is very large and I have 2 1" drains in it, really 3 if I wanted.. But I just don't see a reason to run a ton of water through the sump.. It just adds noise and risk.. The more you run down a drain the more can hit your floor if your drain gets a block.. I could have one of mine drains get 100% blocked and still not have water on the floor... IMO your better off using your sump for filtration and oxygenation. Use powerheads or a closed loop for flow...

BTW I use a ReeFlo Barracuda for my closed loop on my 180 and a Dart on my 92

only reason i have a 1260 on my 90 is that it was cheap and available when i was looking :D if i was to buy one new I'd go for a 1250.

I have plenty of flow with the two Vortech's ;)

Wow thanks for all the great information.
So the Mag 9.5 would put out about the same as the Ehiem correct?

I currently have it hooked up for testing but was going today to purchase a Mag12 to use a return but maybe I will just stick with the Mag 9.5 and order the Eheim 1262 instead.
 
I am getting more conscious about the wattage of my pumps and powerheads. Unlike the light bulbs, they run all the time. This is really worth looking into.

Some powerheads such as Maxi Jets consume a lot of power where as others very little. For example, Maxi Jet 1200 powerhead consumes 20W to produce 295 gph (1100 lph) flow while Koralia-1 consumes 4.5 W to produce approximately 375 gph (1500 lph) flow. Where is the extra energy going? It's lost as "heat". I go for the efficiency of Koralia over a MaxiJet in this case. Not only the extra 10 dollars or so is recouped pretty quickly, but also the less heat means less cooling I have to do (fans or a chiller.)

I'm running 12 MaxiJets on wavemaker power strips because they're the only ones I've found that will handle the on/off of a wavemaker without tearing up in less than 30 days. I've got some that have been running for several years. Do you know anything about how the Koralia works on a wavemaker?
 
I heard that Koralia don't take the turning on and off very well. Someone mentioned that it may run on a SEIO controller. SEIO pumps are also relatively efficient pumps as well. SEIO 620 (620 gph) consumes 8 watts, SEIO 1100 uses 21 watts, 1500 34 watts, 2600 55 watts. You can have two larger SEIO pumps on a controller with the pumps at the opposite corners of a tank.

The Seio controller does not stop the "off" pump, it just slows it down

So i have been told anyways
 
The SEIO controller is hugely expensive, though. Gets relatively close to Tunze territory.

I like the Koralia 4 I have a lot better than the SEIO 1500 it replaced. Mainly because the inlets are much less likely to clog and it's easier to keep the whole thing clean. Lower profile, too, puls the semi-magnet mount.
