Re: Airlifts to pull water around a donut pond

Hey Pssymon. Thanks for getting back to me. Sorry to hear work is so busy. Nice to have a hobby! I attached some pictures below. Basically I am thinking a roughly 2 acre pond. The average depth will be around 11 feet, for roughly 7.5 million gallons of water. My thinking is that 100,000 gph gets me...

Re: Airlift pump calculation

Hey Manu, Thanks for sharing that file. I've seen it (or a similar one before). It's interesting, but I can't vouch for it completely. I agree that it would be a good idea to share it on the site, you just did, but I understand what you mean, I could make a 'sticky' topic for it in the future. As lo...

Re: EPDM tube diffusers

I know it’s not efficient , noisy and more expensive but other options are not available in India. Also diaphragm pumps like secoh may not survive the hot humid weather of tropics as well as they do in Europe. Now if I try to explain with what I learned from this forum. From here https://www.airlif...

Re: Airlifts to pull water around a donut pond

Hi Ted, Good to see you back! I can try to find the images. I may have some saved here. Sadly a lot of older images have stopped working due to the big forum update. I'm currently swamped with work but I will take a look as soon as possible. I have some ideas already. But I will get back to you with...

Re: Away for a couple more days

Hi Ted,

I was in Vancouver, but also traveled on Vancouver island for a couple of days. It was quite the culture shock for a Dutch guy like me, I had never been to Canada or the US before. It was very interesting though. :D

Re: EPDM tube diffusers

I agree with Frank. What kind of flow are you looking for? Pressure chamber Airlifts can deliver up to 15000 or 20000 liters per hour. And may be the better / easier option for you. To quote what I wrote elsewhere on the forum: " The membrane disk Airlift Another type of Airlift that some people lik...

Re: EPDM tube diffusers

Hi, There is a topic on the Belgian forum about building membrane disk Airlifts I believe. I will look for it and put up a translation here if possible. The reducers at the size you mention can be difficult to find and expensive. Which is why members on the Belgian forum have made reducers using fib...

Re: Airlift outlet depth

For good efficiency the airlift manifold needs 160 to 180 cm riser pipe length and submersion. In your diagram the riser tube from the manifold is short and submersion is wasted on the very long vents. I asked Marc as well, and he confirmed this. Now that I think about it again it makes absolute se...

Re: Franks pond 2018

Hello, 12 Watt for 20000 l/h is without any filter activity possible! Yes that's what I meant. In real life you will always have losses. The trick is to minimise your losses. As soon as you have bottom drains you loose 2-3 cm, How many bottom drains do you have connected to the Airlift? additionall...
