Air-Lift Water Pumps - Sustainable Engineering for

Aug 03, 2009 · Working Principle of Air-lift Pumps. An air-lift pump is a device which is used to lift water from a well or a sump with the use of compressed air. The compressed air is made to mix with the water. It is well known that the density of water is more than the density of air. So it is obvious and evident that air floats higher than water or to

Underwater Concrete - an overview | ScienceDirect Topics

There are two fundamental principles for casting in situ concrete underwater: the first is that the delivery end of the tremie pipe or pipe from the concrete pump is always kept submerged in the plastic concrete, keeping the shaft full of concrete and ensuring as uniform a flow as possible (see Fig. 4.15), and the second is that wash-out of fine material in the concrete must be prevented.
