No problem. It will be a koi pond with 300 mm membran disc again.

Hello all,

the planning for my next pond to build in 2022 has started.

Dimension: 5 x 4 x 2 meter, 40.000 liter
Goal: 50.000 liter per hour with 50 watt

The linked air pumps are inefficient.

Hallo Chris,

2 bar are 20 meter, are you sure?

Frank

Check out the FujiMACs in the US, they are high efficient.

It looks like this: https://images.app.goo.gl/wXXr7yN4BmJYBKbw8

I use a funnel airlift, 250 mm diameter, 170 cm hight and 5 cm discharge head.

Frank

These airlifts are not efficient and expensive.

For example, I pump 60.000 l/h water with 140 l/min air and 76 Watt.

Frank

Air and water will go in all directions, 360°. Is this really less efficient?

Frank

Hello all,

who has experience with an airlift without 90 degree bow?

The results are partly contradictory.

My interference is to do own tests.

The Gast 1531 seems not to be the best, because the air pump is not efficient. Why that one?

You could use a 160 mm airlift supporting up to 40.000 l/h.

Yes, the disc airlift are good for high output. At my pond I move 65.000 liter per hour with a 250 mm (10 inch) diameter airlift and 90 watt. Even more than 100.000 liters per hour would be possible with disc airlifts. But for a 110 mm pipe it's easier to drill the holes into the pipe instead of usi...

For a 110 mm airlift I would not use a disc. Drilling holes is the better way here.
