New and Unique Features of the Rotomite SD-110
Best Efficiency Point. The Rotomite SD-110 operates at the nominal design Best Efficiency Point (BEP) of 1,475 GPM at 123 feet of TDH (in clean water). The dredge can reach flows of 2,000 GPM and 155 feet TDH.
Easy to operate. Designed with the operator in mind, the dredge has on-board storage in the operator’s station and a 12 VDC power point for the operator’s personal items - i. e., cell phone - with four additional 12V DC circuits, an adjustable helm, and even a built in cup holder. A walkway behind the operator’s station enables safe, easy operator movement from one side of the dredge to the other.
Portability. Weighting only 7,000 lbs, with an aluminum super structure and integrated mounts for most features and four lifting eyes, the SD-110 measures only 24.5 x 8 feet, can be lifted by almost any crane, and is transportable anywhere in the US without special permitting on a regular deck-over trailer.
102 inch wide Cutterhead; 12 foot dredge depth. The Rotomite SD-110’s 102” wide cutterhead provides 8.5 feet of actual dredging width and 12' of dredge depth depending on the model chosen.
Electrical & fuel systems. The diesel engine includes is a marine-duty gauge package an emergency (high temperature/low oil pressure) shutdown system.
Dual power systems achieve quiet and economic operations. Propulsion or traverse dreding. The Rotomite SD-110 comes standard with a traverse system to allow for dredge to be run on a cable system where precision is cruscial, you also have the freedom to dredge where you wantwith the maneuverability of the propulsion system.
Pontoons. Pontoons are 20’ long, aluminum, urethane foam filled, internally reinforced, with integral lifting eyes. The pontoons are divided into 5 sections each of which has a rub strip on the leading and bottom edges for safety.
Sludge pump by Crisafulli's 4” J-Series, submersible, variable speed, hydraulic dredge pump with dual mechanical seal bearing frame.
Auger/cutterhead. Crisafulli’s Cobra cutterhead/auger assembly directly mounted to pump intake, is equipped with dual hydraulic auger drive motors (11,000 in.-lbs) of total digging torque with overall dimensions of 8.5’ width and 1.5’ deep.
Propulsion System. The Rotomite Series has a completely new and much more powerful propulsion system, shown below, which adds versitility (speed, thrust, and maneuverability).
