Dino6: Our Sediment Removal System
The Dino6 sediment removal system is comprised of a small dredge manufactured domestically. The Dino6 measures just over 22′ long and 6′ wide and is less than 6′ tall. With a wet weight around 3800 pounds, it is a very lightweight portable dredge, with a low cost of mobilization, and a small footprint.
Mobilization costs are a fraction of a typical six inch dredge. The launching and loading are more like a boat than a conventional dredge or excavator. There is no damage to the shoreline or tracks to be repaired.
Our lightweight and portable dredge is powered by a Cummins diesel engine. The system is simple and easy to operate. It excavates sediment with a durable, high-torque, direct-drive cutter head and pumps at rates up to 1500 gpm through the highly abrasion-resistant, hydraulic submersible dredge pump.

1. How deep can the Dino6 work?
A: The Dino6 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 Dino6?
A: The Dino6 is rated at 1100 gallons per minute at 50 feet of total dynamic head. Which 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 Dino6 clear the vegetation off my lagoon?
A: The Dino6 will struggle with many reedy and fibrous forms of vegetation. It is not a difficulty of 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 Dino6 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. Do you offer options for a self-propelled Dino6?
A. We realize that there may be few situations where this might be nice, but don’t believe effective pressures can be delivered to the work surface with an outboard efficiently, think of swimming against the side of a pool, you can exert a lot of energy (fuel) but not be putting much force on the wall. The travel cable counters wind, current, pipeline forces and enables certain and accurate tracking of cut paths.
7. How much pipe fits on the trailer?
A. The custom trailer available from Geoform will carry 800 feet of pipe plus the pipe components of the floating discharge on the pipe rack.
8. What is the best way to get the Dino6 into the water?
A: The Dino6 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 crane or boom truck needs.
9. Booster Pump Compatibility?
A: One of the three limitations inherent in the use of the Dino6 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.
10. 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.
11. How many cubic yards will the Dino6 move an hour?
A: 1 CY of in situ 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.
12. How much do I charge and/or how do I bill this work?
A: Please call us to discuss. We are putting together a contractors guide that will help explain the many ways to approach the commercial aspects of this type work and the potential pitfalls.
1. How do I know when to service my Dino
A: There are several easy ways to tell what moving parts and wear items need to be repaired or replaced based on a variety of circumstances. The best way to know how to properly maintain your Dino product is to call or email us so we can talk you through what services should be performed and why.
2. Do you sell pre-owned Dino Dredges?
A: Yes. Occasionally we have pre-owned Dinos for sale. When available we can also assist in locating Dinos for sale around the country.

- Grease Bearing Block and cutterhead.
Once a week during operation:
- Drain water separator of any water that has collected. Open the valve on the bottom of the separator to drain water until diesel runs out.
- Check Pump case nuts to make sure they are not damaged or missing, replace if needed. This prevents pump stand-off bolt damage.
After First 100 hours:
- Change engine oil and filter. Use a high-quality, non detergent 30w motor oil. We recommend using Philips – Power drive fluid 30.
- After first change switch to every 250 hours.
Important Maintenance to complete after 250 hours:
- Change Fuel Filters
- Change hydraulic oil filter.
- Check the bearing block for play, front to back and side to side. If there is any play, repair or replace the bearing block.
- * Check the bottom door for wear. This is the opening to the pump through the cutterhead. The diameter should be 6” if it is more, around 6 ⅜” – 6 ½” in diameter, replace the bottom door. If this is not addressed it will affect performance.
- * Check the dog house doors. There should be no more than 1/16” space around the bearing block shaft.
- * Check the impeller for wear.
- Make sure to always change impeller bolts when doing the scheduled maintenance. They are ⅜” x 24 – 1” long grade 8 bolts.
- Check for loose or missing cutter head teeth.
- Check the rubber drive blocks for wear, these a very important. These act as shock absorbers that protect the cutterhead motors.
- Check all the pulleys for wear. Replace any missing pins.
- Replace nuts holding the cutterhead to the pump.
- Change the air filter and check the alternator belt tension.
Important Maintenance to complete after 1000 hours:
- Check the discharge pressure diaphragm.
- Check windlass cable drive pulleys.
- Check the hydraulic oil. Send a sample to get checked for the presence of water or other contaminants. If there is water or contaminants present, chance the hydraulic oil.
*Indicates that these specific guidelines should have increased maintenance checkups if our machine is being used in harsh environments. Check frequently to avoid catastrophic mechanical damage.
