Hello Roy,

exciting would be a characteristic curve for an airlift like we know from water pumps. For example from 0 to 10 cm discharge head.

.

Best would be zero mm.

Yes, the air could escape.

@Marcje

Have you ever tried the airlift without 90° like here from Norbert?

Frank

Okay, thanks.

One the right side you see my T-piece. That would be used instead of a 90° elbow.

The end obove I would close.

@Marcje: If it's a T-piece and closed overhead, do you expect more or less flow?

Hello,

every air lift pumps and aerates, that's just physics. You want to pump 100 feet up? That could be possible, but is not the focus here at pond airlifts. Therefore we do not have any experiece for 100 ft. discharge head.

Best regards,
Frank

Thanks, that is my result too.

What do you think about smaller air pumps in parallel?

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.
