Re: Good pump and attachment?

The linked air pumps are inefficient.

Re: Airlift pump calculation

These airlifts are not efficient and expensive. :nono:

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

Re: Airlift without 90 degree bow

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

Re: EPDM tube diffusers

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.

Re: EPDM tube diffusers

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...

Re: EPDM tube diffusers

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