FAQ

1. HOW DEEP CAN THE DREDGE WORK?

A: The dredge can excavate at a thirteen-foot depth in standard configuration, a three-foot boom extension allows for an additional two foot of cutting capability.

2. WHAT IS THE DISTANCE I CAN PUMP WITH THE DREDGE?

A: The dredge is rated at 1100 gallons per minute at 50 feet of total dynamic head. This means it can deliver 1100 gallons per minute 50 feet straight up in the air or (based on frictional losses in the pipeline) it can deliver 1100 GPM over 800 feet horizontally. The specific gravity of your sediment can affect the distance you will be able to pump. Velocity in the pipeline is critical to keeping heavy materials in suspension. A booster pump can be used with this system.

3. WILL THE DREDGE CLEAR THE VEGETATION OFF MY LAGOON?

A: The dredge will struggle with many reedy and fibrous forms of vegetation. It is not difficult for the pump to put these items into the pipeline, the problem lies with the cutter-bar rotation. The reedy vegetation wraps around the cutter bar and becomes tightly wound and very difficult to remove. The cutter bar has teeth to loosen material but no cutting action. Lighter surface grasses and other plants which wrap but are easily removed will just present many more short stoppages for clearance.

4. WHAT TOLERANCE FOR TRASH AND DEBRIS SHOULD I EXPERIENCE?

A: The submersible pump on the dredge can pass debris between baseball and softball size (approx. 3″). The pump and impeller are constructed of ar-400 material that will not be damaged by submerged material including gravel, cobblestones, concrete, tree branches, etc. Materials caught or obstructing the pump are simply removed and operation continues.

5. HOW DO I RUN THE TRAVEL CABLE IN OPEN WATER?

A. The are many options for open water rigging, including a spud barge, sinking an anchor or multiple anchors, jetting an anchor into the mud. We generally expect that you will be working towards your shoreline anchor (lots of solid pull) and gingerly back up towards your open water anchor (no load).

6. HOW MUCH PIPE FITS ON THE TRAILER?

A. The custom trailer will carry 800 feet of pipe plus the pipe components of the floating discharge on the pipe rack.

7. WHAT IS THE BEST WAY TO GET THE DREDGE INTO THE WATER?

A: The dredge can be launched from the trailer on a boat ramp or sloped ground. Also, it is equipped with lifting eyes welded onto the pontoons for a crane or boom truck needs.

8. DOES IT HAVE BOOSTER PUMP COMPATIBILITY?

A: One of the three limitations inherent in the use of the dredge can be overcome by the use of a properly sized booster pump. Limitations of pumping distances and extreme elevation changes can be negated with the additional capabilities of a booster pump in the discharge line.

9. HOW CAN I TELL WHAT TYPE OF MATERIAL I AM PUMPING?

A: Prior to starting a project a sample can be taken of the sediment to be removed, its content will tell you many things about the job including how far you will be able to pump the material (based on weight and velocity needed to maintain suspension), what type of flocculant you will need if using a dewatering device, and what the shrink rate will be for calculating the total yardage of dry solids to be moved or contained.

10. HOW MANY CUBIC YARDS WILL THE DREDGE MOVE AN HOUR?

A: 1 CY of material per minute is a good baseline for this system. Repositioning, debris clearing, and other stoppages will result in less production. Soft, soupy, gassy materials will exceed these estimates dramatically.

11. WHAT TOOLS SHOULD I HAVE ON THE JOBSITE WHEN USING THE DREDGE?

• GREASE GUN; preferably one with a rigid end (rather than a hose) that makes it easier to grease the cutterbar and pump bearing block.
• SET OF STANDARD HAND TOOLS; for tightening cable clamps, etc.
• SAFETY FLOTATION DEVICES; for persons on dredge and in boats.
• SMALL FLAT-BOTTOM BOAT; for accessing dredge, refueling, etc.
• SMALL PRY BAR
• CABLE CUTTER; for cutting the 1/4” Travel cables.
• SLEDGE HAMMER; for driving anchor stakes.
• WALKIE TALKIE
• 10’ – 12’ PVC PIPE or 2×4 for Depth Gauge
• 5 GALLON BUCKET (onboard storage of tools, towels, dish soap)
• BOTTLE OF DAWN DISH SOAP (for oil sheen if spilled/leaked)
• LENGTHS OF ROPE (tie offs for dredge, pulling discharge pipe, etc.)
• ROLL OF FLAGGING (for marking cable runs in traffic areas)
• FUEL CAN
