Remote Operated Submersible Dredge

This submersible dredging system is unique to the market and is changing how companies mine for gold and perform sediment removal. All subdredges are equipped with our dredge pumps or slurry pumps powered hydraulically or electrically. These pumps are the most efficient at removing solids or abrasive material.

  • Can be fitted with pumps from 4 inches to 10 inches
  • Production rates up to 4500 GPM or 400 cubic yards per hour
  • Able to operate remotely
  • More cost efficient than traditional dredge systems
  • Non-clog design
