There is an airlift demonstration model (In apple quicktime format for
download in the files section in the pulser pump group
http://groups.yahoo.com/group/pulserpump/files/ It shows a model
airlift pump with about 3 ft of depth which pumps to 6 feet higher
through 3/4 inch pipes. Metric 90 cm deep pumping to 180 cm high
through 20mm pipes
The model is powered by my humble assistant Laurie with a large
bicycle pump. The slowness of plug flow up the model surprised me. (I
have not done airlift in see-through pipes of this size before).
A warm welcome to our new members.
