High volume eco-pump

[Bob Hart]

Ed,

the smallest version there is the HP-20000, which at zero head looks to deliver 20000 litres or 4395 gallons/hour, for 0.56 amp, which equates to around 130 watts. Looks good, it has a maximum head of 3-metres, so I wonder what it will output at a 1-metre shower head?

When I saw these at the show, these smaller versions had a smaller slot in the bottom casing and I think this auction is saying it is 3mwith the larger models have 10mm slots.

Good price though at £118

Am awaiting a reply from Roger, would prefer to purchase in the UK if I can

remember chaps that you might get a good price in the EU, but the HM customs will bill you 17.5% vat as it comes into the country

Wrong Jane, as long as you buy it withing the EU and pay the VAT in the country where it was bought, there is no VAT due. If you buy it duty free, defer the VAT or reclaim the VAT as an export item in the country you bought it, then you will be billed for 17.5%

Their German store (on Ebay.de) has the smaller models too (12,000lph and 16,000lph) for a little less then the 20,000lph model. Like you I'm waiting to find out what kind of output they'll have at 1m head to pump over my shower. I'm waiting on Roger's reply too and would prefer to get it over here too if it's not too much more than the European prices.

I still think I might need a large case around the pump case just to prevent any damage as it'll have to go straight in the QT pond. Depends how fierce the suction is really I suppose!

Heard anything yet Bob? I haven't yet, but I guess this time is pretty busy for him and as it's not long after a show.

Michael,

thanks for the tip, found the full page ad.. Would still like to see some pump curves, I'll have to email them.

Roger hasnt come back to me yet, may have to phone him.

[Bob Hart]

Just emailed that email address and got this reply

Cheers Micheal for the address but they're the guys Scott linked to and the ones off Ebay. If their e-mail there isn't working have to send a message via Ebay maybe? To be honest I'm just thinking of ordering the 16,000lph one as it should be complete overkill for my QT even if it loses half the flow and I don't think it'll be that bad as the maximum head is 2.8m!

I did a bit of playing around and tried to estimate a flow rate at various heads for the 16,000lph pump

First I assumed that the maximum flow is at 0m head (and I know it wouldn't run that well due to friction head in the pipework but this is only for a very rough approximation) and that the flow is 0 at the maximum head.
Then I assumed that there was a straight line between those two points on a graph (which there wouldn't be as every pump I've ever seen has a performance curve above the straight line and then tailing off nearing the maximum head). This really rough guess says you would have a flow rate over over 10,000lph at a 1m head.

As long as the pump has a performance curve above a straight line then it should be over 10,000lph at a 1m head. That's over 2,200gph at 1m head for 100W.

I looked up the addy and I have the same guy sam@aquarium.lu

I send him emails direct and have no trouble. He usually replies quite quickly. I don't think they have a pump curve chart they can send you. A shame as it is an important bit of info when choosing a pump. Still you can try.

I'd try emailing them again as I'm sure it's a server malfunction.

I e-mailed the guy from the address Scott gave above and he's replied already! Excellent speed and the reply had attached the pump performance curves! I'm hope he won't mind me posting them here for everyone to see, it'll help his sales after all I'm sure!

My projections of a straight line rather than 'curves' weren't far off it seems, but their straight lines start off further down from the rated performance. Looks like I might need the 20,000lph rather than the 16,000lph!

Any chance of an idiots guide to the chart ? What am I looking for ?

The x axis (along the bottom) shows the flow rate and the y axis (up the side) shows the height. So for a certain head you look at the height you need (1m in my case) and read across until you get to the flow rate you want, or look at where the sloping lines for each pump crosses that height. In this case if you look at the 1m height and track across you can see the 16,000 pump line (the yellow, or is it light green? I'm colour blind!) is at about 6,000lph on the x axis whereas the 20,000lph pump is at about 10,000lph. Does that make sense?

Thanks Ed

I got that,for some reason I was looking for the wattage / power consumption.
