A lot more detail regarding the physical site conditions, quantity of material required, type of material to be pumped together with an idea of its composition, distances and height differences involved, prefered motive power to drive the pump unit etc etc etc.

The US Coast Guard has responsibility for maintianing the shipping channels of Mississipi and Missouri rivers. They use barge mounted dredges to remove sand bars left by the changing currents of the rivers. A Google search of pump + dredge brought up site for
www.twinkleco.com
The typical dredge has a boom with rotating cutter to loosen the bottom material, and air injected into the center of boom hollow shaft to lift the fluid column. The air lift has adequate head for moving sand and material into towed barge or to nearby shore. A secondary pump is likely needed for more distant or higher stockpile of sand. The GIW slurry pumps mentioned by wimple are good stout units. Another would be Galigher-ASH pump. There are other pumps - depends on size needed.

Apologize me , to not answer early.

Airlifts are great provided the water's deep enough for the entrained air to expand a bit as the air/water/sand column rises up the tube. They really come into their own in the 10m to 20m depth range.
If the water is shallower than five or six metres, you'll get more efficiency from a jet lift - a device which uses a high speed jet of clean water to entrain and move a much larger volume of sandy water (very much like a salvage eductor).
Google searches to try:
Jet Lift Dredge (Lots of very shallow, low volume stuff for amateur gold diggers)
Archaeology Water Dredge (Larger scale stuff - mostly applications that move silt from one part of the seabed to another).

They were originally developed in Japan for mining sand from the ocean floor. I don't remember the exact %sand they were designed to handle but it was a significant amount of sand rather than water with 'some' sand in it.

Just to quarry sand to be used at construction.

We have some pretty smart guys with a lot of experience in these forums, but we don't have crystal balls.

With all the help, I got from you, now I have a clear view to follow up to end my project.
Thanks again.
