Jeboa pump?

[Yabbie Dabbie Do]

Just wondering if any body is running the new eco 2 10000 L/hr pump. Herd bad things about the earlier jebao pumps but considering it is half the price of a laguana and uses 50w less to run I am considering getting one to run in my sump.

[mjoconr]

I have them, got them from fish-street.com. There so cheap I simply buy a backup.

[Buccal]

Without looking at them, I'd imagine they'd have a low head height, and maybe have to upgrade size which would increase wattage anyway.

If its just one tank your running to being a lowish height it wouldn't matter as much.

I personally find the pondmax a killer pump,, has a really good strong head height and don't need to use a bigger pump to get water volume up there.

Mind you I have to pump 2.3 meters high and need 4 x 20,000 L/H DWP pondmax pumps lol.

But this high head heigh and full on volume needed really tested out some pumps I've tried.

As far as getting needed/desired volume and keeping wattage to a minimum.

[Chuckmeister]

I recommend getting the best quality you can afford. If its these then go for it but from my experience cheap pumps fail often and usually at the most in-opportune times.

Personally I normally get dirty water graded pumps as you know they are rated high for reliability. My pondmaster recently died after more than 10 years of continuous use.

[mjoconr]

All the AC pumps I've looked at use way to much power and are noisy.
85watts for a pondmax 3000L/H - head to zero flow is 3 meters
25watts for Jebao DC3000 - head to zero flow 2.7 meters
Sure the cheap DC pumps have had issues in the past, any tech which is being built cheaply is going to have troubles initially.
The Jebao pumps have been on the market for about 5 years now and have been though a number of iterations.
The failures from everything I've read have been the controllers not the hardware. It seems to me that these issues have been fixed.

I've got an older model which has been running over a year now and I'm sure the newer ones will be evern better.

Sure if I could afford to purchase a German made DC pump I would, but there 6 times the price.

mjoconr,,, your homework isn't thorough enough.

Pondmax make various types of pumps to suit particular situations.

The pondmax pump you mentioned is the incorrect pump to use for the situation.

The three common pumps that pondmax make in the 3000 l/h range are:

Water fall and filter pump AP 3000 DW (dirty water) 35w.

Water fall and filter pump PU 3000 (also a dirty water) 35w.

Water feature pump PP 3000 85w.

I use the AP series which is exact in what they indicate with head height performance charts.

I did try Jeboa pumps, because my wattage usage is phenomenal, and the low wattage is even more attractive with the larger pumps they do,,,, but as far as I was concerned they blatantly lie on the pumps performance,,, and these pumps barely work at 60% of what they state in head height performance,,,,, the higher up you go in head height, the more the inaccuracies blow out.

I used there 20,000 liter pump and I think maybe 180w or 200w,,,, and it performed close to a 12,000 l/h pondmax.

I use pondmasters (not pondmax) on my 4x ray pens because I use a float system for water entering pens, which need some pressure to work correctly.

Pondmasters really send water fast and I think from memory they have one of the best head heights,,, but they use a few more watts than other pumps.

Pondmax is used for all the Cichlid tanks 20,000 l/h x 4.

Oils ain't oils.

And pumps ain't pumps.

People buying two pumps speaks volumes about the quality of Jebao, the website is enough to turn me off, look at QLDAF the guys there are saying the Jebao last 18months at best, seems like a false economy to buy two pumps which will last you less than 4 years.

[Dean24]

As i understand, the gen 4 water pump impeller is a metal "water agitator" like that of the gen 2 ST185...

have you got a picture to illustrate ?

[mjoconr]

No but I did notice that the impeller was very different to the first unit I purchased.

QLDAF has a number of threads and a few which are current are actually positive.

Look I understand the history of the brand, but they seem to be doing very well now. Buying two is just a backup against these past issues. I expect that it will last for many years

[PlecoSam]

mjoconor all good young fulla everyone justifies their own purchased be they cheap or expensive, I deemed them to great a risk but I do hope yours last for many years.

[mjoconr]

40 years old is not young over half my life is gone. The person who asked the question has enough views to help them decide.

As always this has become about the person not the issue.

[PlecoSam]

Interesting

[Buccal]

My experience is with the older models,,,, I should have stated.

I haven't looked at or into the newer models.

[Yabbie Dabbie Do]

Going by the price and wattage on the new models justify giving them a go. Being half the price to by and using half the wattage to run even if they only last a couple of years it is financial better to trial the jebao especially with electricity prices these days. I think i will trial the new eco 2 and give a up date.

[Buccal]

Mmmm, but I still reckon its quite possible they may still not perform at the higher head heights matching what they state on their performance graphs.

Sitting a small to moderate size jabao in a sump and pumping up a meter to a hand full of tanks isn't really putting it to the test.

Buying a pump should be more about the wattage it will consume pumping just the right amount of literage you need.

I think most would find, buying a quality performing pump would deliver water a lot better and may allow you to even downsize in size and wattage compared to the size needed with a Jabao.

When people talk of energy efficient low wattage pumps,, these are generally low head height pumps used in situations where water is being pumped across with a slight or minimal elevation.

Larger outlets and impeller and higher gearing will scoop and push more water per second,,, but will labour and be governed once under pressure of head height.(heavy water pressing back down due to fighting gravity).

Higher wattage pump impellers run faster and geared lower with more wattage for back up momentum strength which will compensate to beat gravity better. These are designed for pushing water up and not across.

A energy efficient low wattage pump with low head height in a pond situation pumping water across slightly elevated would be the most efficient choice for less power consumption.

A higher wattage pump with high head height in a breeding room pumping water up to the top of the top fourth or third banks and needing water volume to deliver to many many tanks would be the most efficient choice for less power consumption.

If you used a low wattage pump with low head height in this situation,, you'd have to upgrade the pump size dramatically to make the head height and the wattage would surpass that of a high head height pump in usage.

Many people seem to get confused which is for what and what for.

A quick google, for my own interest found: http://aquaponics.net.au/forum/threads/problem-with-new-jebao-cmm-10-000l-h-wet-dry-eco-pump.5658/

What flow do you actually need?

Is the pump mission critical?

It seems you have convinced yourself so buy one and report back your findings, best of luck!

[Yabbie Dabbie Do]

I only need 4500l/hr for 3 times turn over. So allowing for loss of 2m head height i thought the 10000l/hr pump would be enough for at least 5000l/hr turn over. The thing with that review sam is it is dated 2013. Which i know theses pumps had a few demons over the years. Thats why i started this thread to see if any body has the new blue coloured eco 2 series.

[PlecoSam]

And is the pump mission critical, can you afford a failure? backup... etc?

[Buccal]

Using a 10,000 l/h pump to receive 5000 l/h.

Wouldn't using a high head pressure pump of say 7-8000 l/h to achieve 5000l/h be a lower wattage use rather than a low head pressure 10,000 l/h pump wattage use ????

[PlecoSam]

Good question Buccal, one would have to look at the figures, assuming the companies flow figures are correct.

[Yabbie Dabbie Do]

How do you accurately test litres per hour running through your system once set up?

[mjoconr]

Fill a known size bucket with water and time how long it takes.

[Chuckmeister]

Personally I think you should post a whole topic on how you plan to set up your tank and filtration. Its hard to guess when you cant get a picture of the setup. head heights, the way you plan on returning the water. Is your sump a vertical or horizontal sump etc

Anyway, my opinion on pumps is that to pump a liquid to a particular height you need energy. There is no escaping it. I would be concerned with head height with those cheaper pumps myself and the strain you are working the pump if you are really pushing the motor.

To work out the flow rate of the water you would have to run the tank and fill a bucket or tub for 30 seconds and multiply the volume by 120 to work out the liters per hour.

Bunnings have some reasonable pumps at a fair price imo. They come with 2 years on them and just take them back to bunnings if you have any issues.

I just put a 6000 liter dirty water pump from there on my tank (2300ltrs roughly) and its more than enough for my tank. The link has a small chart on diminishing returns on the pump. They also do another pump at 7500 but its not dirty water for the same price.

Another thing you have to be mindful of is if you have so much flow running through your tank your return may bog down and you'll see the water level on your tank rising. Gurgling can also be a pain with too much water flow.

[Yabbie Dabbie Do]

Ended up sticking with the old faithful and got another laguana 11000 l/hr. I have finished building the sump and rack now. Is there someone on the forum I can mms the photos to so they can put them up for every body to see.

[mjoconr]

I've taken to using taptalk on my phone to upload images and video. So if you have a smartphone try that.
