Simply Koi and More Koi

While at the Dutch show I came across this stand from a company in Luxemburg that make a very interesting pump. This pump moves HUGE volumes of water at a very low wattage indeed. The design has it's limitations but I feel these can be overcome with little problem. Strangely enough, I feel one of the greatest problems is the shear amount of water these pumps turn over.

This pump has an optimal head of just 50cm above the water's surface and the pump itself must be dry, not submerged.

All that said and done, the SMALLEST model uses 110 watts (0.33 amps) to move an amazing

28,000 l/h (or 6,200 g/h) That is the output of three Aquamax 10,000s for the price of one!

The price is well worth the trouble as well. about 200 quid.


Now for those of you with Bakki Showers who need to move lots of water up a bit higher they have a different model. The HP series uses a bit more lekky but I imagine it is still cheaper than most pumps.

The come in a range from 3,500 g/h to a whopping 12,2500 g/h

The 6,500 g/h model uses only 250 watts with an Hmax of 4.5 meters!

The bad boy 12,250 g/h pump has a power consumption of 550 watts

Is anybody impressed?

Scotty,

Bob and myself was looking at these today and they seem to be just the job for showers and the guy we spoke to runs all his showers with them buy having a settlement chamber which the pump sits in and then 4" pipe straight up to the showers

Bob will be glad of this post as he tends to forget things nowadays so this should jog the old Grey matter

we also saw the second sort of pumps today and noticed some confusing info on the back of one...
it had 240 volts ac 50Hz 0.9 amps and a motor output of 100 W
if you do the math this pump uses 266 watts

so whats with the 100 W

p.s. like the big pumps Scotty. Mark says if it all goes wrong with the uplift thatll be the ideal type of pump.

Gary,
You know I have seen these pumps at the show for almost 5 years running and have never given them more than a passing glance. Perhaps they need to work on their presentation a bit. I do find it a handy bit of kit though. I am glad they where at the SE show so that you could see them working first hand.

I was thinking along the same lines as you suggest; letting the drains gravity flow into a sump (vortex?) and pump it directly up to the shower.

In regard to the eco model, this could be used in a standard gravity flow bay filter but placing the pump after the last bay and then pumping the water up into a sump a foot or so above pond level and let it flow by gravity back to the returns. I do feel you would need to take some special precautions on how you installed the UVC.

There in a bit of confusion on the issue of the power of the pump itself Jane. My advice is ignore it. For example the HP-30,000 list the power index of the pump as 100 watts and the consumption as 250watts. I think it is nothing more than wires getting crossed in translation someplace. The important things to know are the Hmax, power consumption and the turnover rate.

The one thing I would still like to see it a graph showing the output in relation to the pump head so people would have some idea how much turnover they would have at what height.

B.Scott

you need to ask them for some samples and do some home testing.....

Scott,

Your second picture is the pump we saw today, being shown by Isle of Ely Koi. The pump was totally submerged though, in a big tub of water, just recirculating up to a shower bar. Certainly looked impressive though and 250 watt for roughly 11,000 gallons/hour.

Need to find out more, would be good to see a smaller veriosn doing around 5000 gallons for say 150 watts?

.... and Bob that was with about 1mtr head, it was very impressive (but like others the wattage did confuse us)

Bob,
You won't get 11000 g/h with the 250 watt pump. As Jane says there seems to be some sort of mixup with the pump's "power" and it's actual power consumption.

Take a look at the link below:
Select POND PUMPS the top of the left hand list
Select PIPE PUMPS from the drop down list

If you also wish to see the eco pomps are listed under LIFETECH PUMPS in the same dropdown list.

Now look at the power consuption and ignore the power rating but look at the figures in red listed REAL CONSUMPTION

Yes the guy on the stool did tell us that the power on the pump was not the real consumption and i believe they are looking into it or doing a chart

Hi All

I think you'll find that Jane is right.

The specification label on the pump stated that the pump OUTPUT is 100W - but you have to put 250+ Watts IN in the first place.

Cheers

Thanks Bob,

I've printed the page off and will have another chat with the guy tomorrow, see what he has to say. Couldnt find anything onthe Isle of Ely website though - http://www.isleofelykoi.co.uk/" onclick="window.open(this.href);return false;

Any more info on these guys? I'm toying with the idea of putting larger pump on my QT and like the sound of one of these instead of a larger Ecomax. The 16,000lph pump only uses 100W according to the website and I could fit it to my shower pretty easily. The price look pretty good on that link B.Scott gave too. Do those of you who know these things think it'd be a good choice for that?

I had a long chat with Roger of Isle of Ely Koi today about these pumps. I still need some further information and I'd like to see a pump curve, but I'm seriously thinking about using one of these. If my memory serves me right one of the models was 250 watt, priced at £204 and the output was over 5000 gallons per hour. Roger gives a 12-month warrenty on the pumps.

My current thinking is to use a 4" bottom drain, 4" valve then open up the 4" pipe to someithing like a 9" pipe and pop the pump in there, like a mini sump. Output pipe from the pump being 4" direct to the shower and a really heavy flow direct over the shower. BHM media already in the shower, so a few bits of poop are not a worry. My 2 x double vortex other filter systems with Static K1 in the first Vortex's will take care of any debris anyway.

The shower is currently fed by an Aquamax 10000 off of the skimmer, which would stay, and an Aquamax 15000 at 215 watts. I was about to add a seive and Sequence 1/4 off of the last 4" bottom drain, which would have added another 250+ watts. If I used one of these pumps, I'd save over 200 watts and probably get a higher flow.

I'll be emailing Roger for full details and to see if I can get any pump curves this week.

Please let us know when you get any more info Bob. I'm thinking of having one of these in the QT pumping straight over the shower. I'd probably have to put a larger strainer to prevent any fish getting sucked up though....
