Alluvial Mining Equipments

Diver-less Dredges

Small dredges with 4, 6 and 8-inch gravel pumps use divers. The work of diver is very dangerous. Collapsing underwater pit will cover up diver, which, in most of the cases, dies suffocated. Also, the diver can't control the flex hose above the 8-inch size. Larger dredges with 10, 12 or 14-inch gravel pumps have to use diver-less system.

The diver-less system has three major advantages:
- higher volumes pumped; better cost-to-income ratio;
- safer in use;
- ability to work inland of the alluvial flat.
