High volume eco-pump

[vippymini]

Bob, i would have thought youd have made a fibreglass recepticle for the pump rather than just a piece of pipe.. its going to need a fair amount of water aroud the pump on start-up whilst the water gets flowing through the pipe from the pond. otherwise its just going to suck it dry.

loos lie everybody is going to look for economy pumps now the Leccy companies are shoving their prices up even further.
also looking at the other type of pump Sotty posted, i can see these mounted in the final stage of the filter ad then piped back to the pond using 4" or 6" pipework.... youd only have the smallest of head, just eough to get it out of the filter ad over the side of the pond. or even through the wall of the pond just about the level of the water

Hi Jane,

That is the one I am interested in, to do the job exactly as you describe. I currently have an Aquamax 12000 doing to job. Plus I have a Wave II pumping to the return to the other side of the pond. With this one pump I will probaly be able to replace the two! Now where do I find a UK stockist!

I'm really itching to try one of these...

Scott, that website you posted, have you dealt with them before? The site seems a bit peicemeal and not very professional so I'd be a bit wary ordering from it. Also can anyone think of any problems ordering from Europe? I've done it before with little aquairum bits but nothing this large. We are all in the EU and Common Market after all...

I'm sure I've seen these and a few others models advertised in the KOI mag.

Ed,
I have never actually bought anything from them before but as I said they have been around at the Dutch show for at least 6 years that I can remember. Possibly even longer than that.

I think the one thing you should remember when fitting one of these pumps is to be sure you pipe work can deliver the water to the pump so it doesn't run dry. 6200 gallons an hour is a whopping gob-smack of liquid to pull through a single bottom drain. The people who make them tell me that you can actually use a dimmer switch to adjust the pump rate though I have no idea how this would effect the power consumption. If I remember correctly, dimmer switches tend to suck the power off the pump and turn it into heat. Or am I wrong? Any sparkies out there?

I also wonder how much noise the pump motor makes. The setup they use to display the pump has it gushing out the end of the pipe into the basin it is set up in. The splashing noise makes it hard to hear how much sound the pump makes.

That's where my current thinking is Scott. As the pump will not be directly connected to the bottom drain pipwork, it's not sucking through the pipe, just pumping out what the pipe can deliver to the larger sump pipework. I'm going to rough out some drawings and then get some more information soon.

[B.Scott]

I don't think fitting one of these directly to a pipe is even an option Bob. Like you say the pump needs a sump of sorts to suck the water out of. But if one can put a dimmer on the power in and regulate the pump speed that would be a great help! Not every one needs to move that much water and as far as the eco model goes, 6200 g/h is the smallest model.

[Bob Hart]

Is 6200 at zero head though, add the height of a shower and what's the output then? It may drop off dramatically, it may not - need some pump curves first.

[B.Scott]

The manufacturer told me the optimal head height is 50cm This would mean you need enough feed to the sump to ensure that the level doesn't drop more than an inch or two. The pump itself is mounted at a fixed height above the the sump. I assume the best result comes from letting the water flow from the top of the pump outflow as freely as possible. The exit pipe is 110mm and my thinking is that this would go gravity flow back down to the returns. You might in fact want to branch the pipe off into several smaller returns to avoid having a 110mm return. The ideal situation would be to mount it as Jane's has on her ponds. The pump is right next to the pond itself and you just pump the water up and over the edge directly into the pond. In such a case you wouldn't even need an air pump as the splashing water would have much the same effect with aeration.

Scott,

We're discussing different pumps, the one I want is the one which is submersible. Therefore 'heat' to me is the pumping head, not the distance above the water level where the 'other' pump is mounted onto the 'T'.

I'm thinking of this one too. The 16,000lph one to be precise. Pipework won't be an issue for me as it'll just have to go in the QT pond itself. I'm just thinking of a larger cage around the pump cage to make sure that no fish are damaged. I'd then simply use 3" pipe up to a 3" spray bar over the shower.

Thanks for the info on the company Scott, I think an e-mail to them is in order!

[Bob Hart]

Ed,

It waqs Isle of Ely Koi that I was taliking to at the wekend, email Roger who is the owner. There is nothing on his website about the pumps though, but here's his email addy - roger@isleofely.co.uk

I've already emailed him a couple of questions this evening

[eds]

Cheers Bob.

I was looking at the European source Scott was on about. I've found them on Ebay.ie and the same compant has them listed there. One of the 20,000lph ones is going for £19.34 at the moment, though there's a while to go... The Buy it now price is £118.67.

I will e-mail Roger though (thanks for the address) and see how much he will be able to do them for. Would rather pay a bit more for a British source as you've got a contact just in case then! To be honest the 20,000lph one will probably be too much for my QT (really the 12,000 one might be!!!). I've worked out I've got a 1m static head from the water's surface to the Shower (including the 3" pipework that I'll have to put on top) so just need to know roughly what the loss will be at those kinds of heights. I hope the 12,000lph or 16,000lph model might be able to give me about 2,000 gph at that head!

Ed,

I'll have to look on Ebay as well, but I wont outbid you - LOL

Roger will give a 1-year guarantee, does the ebayer give a guarantee?

It's in German but yeah they say, "Ware ist Neu und Garantie 1 Jahr gueltig". Product is new and there is a valid 1 year guarantee. Here's the link to the buy it now auction Bob, http://cgi.ebay.co.uk/ws/eBayISAPI.dll?View ... :IT&ih=012" onclick="window.open(this.href);return false; Just look in their shop for the other auctions. It's the same shop as Scott gave the link to as far as I can see, just their Ebay shop.

I reckon I'll need the smaller versions for my QT so bid away!
