SRS Crisafulli RotomiteTM - 8000 Dredges

 Cabled diesel 8 inch dredge

The Rotomite-8000 offers a range of Performance Capabilities

“Provides customers with BEST VALUE”

  • Dredging Depth. 28 feet standard (up to 40 feet optional)
  • Cubic yards of sludge processed per hour. Up to 325 cubic yards
  • Discharge volume. Up to 3,850 gallons per minute @ 180' TDH (water)
  • Dredging Speed. Up to 25 feet per minute
  • Width of dredging Cut. 10 feet
  • Available Cutterhead Torque. 19,000 inch/lbs
  • Draft. 27 inches
  • Discharge distances and variables. *Pumping sludges and slurries.

*An important feature of SRS Crisafulli’s hydraulic dredges is their ability to pump dredged sludges and slurries over substantial distances to remote disposal sites.

The actual distance in a particular application depends on several variables including: the nature of the slurry – i. e., the specific gravity, weight, and concentration of solids in the slurry, the model and power of the dredge, the size of the discharge pipe, the topography of the land over which the slurry is pumped – i. e., vertical elevation change from the dredge to the discharge site, whether or not a booster pump is installed in the discharge line, and, perhaps most importantly, the experience and skill of the dredge operator.

SRS Crisafulli offers consulting services, at no cost to the customer, by its experienced engineers operating from the Glendive, MT Factory address during the sales process to properly specify and size its dredges for the customer’s planned application.

If a site visit is required to properly specify a dredge for the customer’s application, travel and per diem charges may be necessary. SRS Crisafulli typically provides dredge customers worldwide with installation and training services by experienced Factory technicians as part of the standard specifications of a dredge sale.

New and Unique Features of Rotomite-8000

While many features of the Rotomite-8000 are similar or identical to the Rotomite-6000, the Rotomite-8000 has several new and unique features that increase productivity and versatility.

Best Efficiency Point. The Rotomite-8000 will operate at the nominal design Best Efficiency Point (BEP) of 3250 GPM at 120’ TDH (in clean water). Depending on power usage of other dredge functions, the dredge can operate a high BEP of 3850 GPM @ 180’ TDH. The dredge can even attain flows in excess of 5000 GPM and can reach total dynamic heads as high as 260’.

Best Value. The foregoing capabilities result in maximum versatility, minimum operating costs, and “Best Value” for the customer.

Portability. The Rotomite-8000 is transportable anywhere in the US (as is the Rotomite-6000) on a step-deck flat bed.

126 inch wide removable Cutterhead. The Rotomite-8000’s 126” wide removable cutterhead provides 10 feet of actual dredging width without compromising the dredge’s portability. The operator in the field can attach or detach the cutterhead to or from the dredge in 20 minutes by means of six bolts, four pins, and two hydraulic quick couplers.

Bent Ladder. The Rotomite-8000’s bent ladder design eliminates all flexible hose running under the dredge and associated service issues.

Two-Speed Traverse. At the flick of a switch the Rotomite-8000’s two-speed traverse enables the operator to achieve traverse speeds of up to 125 feet per minute with the cutterhead disengaged. Such high speeds are particularly useful when backing across a pond on the traverse cable to cut another swath.

Quiet Operation. The noise level in the cab is below 85 decibels - generally considered comfortable without earplugs.

Weeds or Stringy Material. Open impeller is a self-cleaning design that passes most stringy material.

Hidden Traverse Cable. The traverse cable is below deck level from the cab to the rear of the dredge resulting in elimination of cable guards running the length of the pontoons.

Walkway Behind Cab. The Rotomite-8000’s 24” wide walkway behind the cab enables easy access to the opposite side of the dredge’s forward section thereby increasing operator convenience and productivity.

Great visibility. Note the Operator's clear view of dredging operations from the forward positioned cab with large windows on all four sides on the Rotomite-8000. The new cab (with optional air and heat) is accessible from either side of the dredge for improved convenience, productivity, and safety.

Cobra Cutterhead. Observe the unique opposing augers of the cutterhead designed to drive dredged material towards the center of the cutterhead and directly in front of the pump intake for maximum capture of solids, highest efficiency and reduced turbidity.

Safety guard rails. Note the guard rails on each side of the dredge and flanking the ladder.
