Return pump recommendation!

What do you think of this one that I found

What is Close loop flow system? i don´t know.

A closed loop flow system is used in place of powerheads in the DT. The Vectra pumps have a closed loop mode with variable flow settings specifically for this application.

I in my DT use Vortech and I have Reeflink, that's why Vectra is one of my options but I'm not sure that it really pays to pay what they are worth.

Like I said, I like the Ecotech products. But, I recognize what they are. They are not a top quality product. Are they better than Jebao? Probably. Are they 3 times better than Jebao? Probably not, unless you want the features that they offer. For some applications I see the Vectra as being worthwhile. I wouldn't discourage someone from using them as a return pump, but I wouldn't recommend it either.

I don't believe they make a model that will hit the flow rates you are looking for.

Yes, I think the one that uploaded the link is the biggest one.

Thanks for explain me that closed loop system.

I'm not even going to pretend to know what 'coming soon' entails, and most likely not soon enough for you Roberto, but I thought I would throw this in there. I will say that I have had success with my Varios-6. Though I have not had mine for long either, so I cannot speak for the longevity of it.

Edit: I forgot the link VarioS-8

If you really want reliability at a reasonable price point you may want to reconsider having it controllable. You can get some tried and true AC pumps at a very good price. Of course, I don't know your system so there may be a reason you need it to be controllable.

@Roberto CRC I'm thinking in this mode. I would question your need for adjustable flow in your application. There really aren't too many situations that would call for it.

If your situation really doesn't call for adjustable flow, then you have much better options in AC pumps. You'll still have dead-silent operation and low-power usage...it just won't be so likely to fail.

(I would still keep a backup pump if this is for anything crucial like your return flow. AC pumps are usually inexpensive, so this isn't such a big deal.)

A new prop for the DCT is $14.99. I would go that route first.

Agreed with much of what has been said already. The question is whether you need all of the functions with a dc pump and what your tank needs are. I've had a good ole mag drive pump on my tank without issues. It basically comes down to what you're willing to pay and what needs you have

In this case that mentions, which ones do you recommend to see in Costa Rica?

 

[Roberto CRC]

If of course it is cheap, but since I live in Costa Rica and do not sell that spare part I have to ask for it on Amazon and wait almost 17 days to receive it. Then on that side first I need a new bomb and then try to buy the new propellant to do the test and leave it as backup.

Danner Mag Drives seem to have a great reputation for reliability if they have them in CR.

You could always get one of these, and if a new rotor fixes your problems you can switch back to the Jebao and keep this as your backup.

Thaks, i already found out in the stores here and I can only find Jebao and Vectra M1.

What do you think by having only those 2 options?

I think only having those 2 options stinks!

I think the Vectra is slightly higher quality than the Jebao. The same Chinese motor manufacturer that makes the Vectra has an identical looking model that sells for $120 with a different controller. (Marketed by Top Eco).
I feel the Ecotech controller is much higher quality than the Jebao or the Top Eco. It also has much nicer features. Just not much difference in the motor itself. Only you can decide if you want to pay the price difference.

If, in all of this it sucks, it is a very limited market and what one brings from the USA, they charge a lot of taxes and if they are liquid products like additives, test or food they have to obtain health permits and another pile of paperwork.

 

[gcarroll]

I did not say have a backup is stupid.
I said buying 2 Jeboas with the idea that one is going to fail is stupid.

As far as the failure rate on Jeboa products, it's all over the internet.
Doesn't take too much searching to find it.

Finally, someone other than me feels this way! Anyone claiming the Jebao (as well as any other rebranded pump made by Jebao) is a fine choice for a return pump, has to be questioned. That question would be:

What is an acceptable rate of failure for a return pump?

 

[schooncw]

Vectra M1. This is the most amazing pump I have ever seen, period! Just plumbed a 120 and it was expensive but so far, worth every penny. Absolutely silent with great features.

The Jebao is a rebranded Waveline, which many people consider a fine pump.

The Vectra uses the same motor as Top Eco and are made by the Shenzhen Hipool Motor Company. You can get the 80W Top Eco for under $100. With the Vectra you are paying for a higher quality controller with nice features. You are not paying for a reliable motor. You aren't going to find a custom built motor for a return pump application for under $500. The setup costs are just too high so many aquarium manufacturers have their products built to the exact same specs at the same factories. Use different color plastics, add a different logo, and without research no one knows any different.

Wow, good info brew! Puts it in a different perspective and should make all of us really do our homework on the products we buy.

Homework is good! And I really hope people don't feel like I'm bashing on Ecotech. I like their products. They are just doing what they can to make their products affordable and using a common design made in China helps with that. There is a reason that the European made motors start at $800+ and don't have the features the Vectra's have.

 

[cmcoker]

I know there's all the Jebao haters but that is all the pumps in my tank (just took down about to start new build)
I have 2 wp-25 that still work fine, they are about 3 years old, 2 pp8 still work 1-2 years. A dct-12000 that's 2 years old, only cleaned once a year.. Still working just fine.

As for why I choose jebao, well, I would like to stay married.

Brew12,
Although the Vectra may be the same motor as the link you provided, I believe it has some dissimilarities.
The power supply which is a primary failure of DC pumps. I am not for certain but I believe the Vectra uses a higher quality power supply. Also a feature often overlooked is the low voltage supplied. eg Jebao 24v , Vectra 36V. I always prefer the higher voltage simply for the fact of lower current draw. Lower current draw tends to heat up less than a 24v hence slightly better reliability. Now, if you are using a high quality 24v then it's a different story, that being said I highly doubt Jebao is using high quality components.
Second on the list of failure would be the controller, hands down Vectra has this feature over Jebao.
Yes you are correct in that it may have far more features than one may need, but the quality is better.
Third comes the pump. Usually pumps on their own are not a concern, except for things such as tolerances between the shaft and bearing as well as rotor to stator. This comes to play when calcification becomes a concern. Take an Eheim motor for an example , I 've gone a year without cleaning, once taken out it did not have a spec of calcium deposit. I can't say that about these new DC pumps yet. This could be part of the motor failures, for which are misdiagnosed for a motor failure.eg(open winding)

Also another spec I would like to mention that nobody talks about and as far as I am concerned is most important, the performance of the pump.
This is where I believe the Vectra stands out. Look at their flow rates vs others of the same pump and you can clearly see others a far more exaggerated.
Without mentioning names , I have seen a test clearly documented on a DC pump which claims a flow rate of 6000l/h and true flow rate was 4000l/h roughly 33% at 55 W. This is insane. As you can see given this spec there are several AC pumps that can come very close or even exceed those numbers.
A quality pump with comparable, if not better flow to some of these DC pumps are the Fluval Sp motors.Not only do they perform well the are just as quiet as some of these DC if not quieter. So all this fuss over DC pumps I truly don't understand, unless you need variable flow.
I can tell you there will be an AC motor coming after the New Year that will be extremely efficient and very quiet.
