The world's most productive 3", 4", and 6" dredges
When used with Crisafulli's patented Pivoting Traverse System and a cabled traverse system, the FLUMP and Rotomite-6000 are approximately 48% more productive than competitive products. Crisafulli FLUMPs and Rotomites can complete lagoon dredging projects in approximately half the time and save owners all or close to the entire cost of the FLUMP or Rotomite over several years from reduced operating costs.
Dramatically reduces down time. Crisafulli’s unique and patented PTS enables the entire FLUMP or Rotomite to pivot 180 degrees within one minute at the end of each forward dredging pass. Without the Crisafulli PTS, operators spend much time repositioning the dredge between dredging passes when a dredge is run on a cabling or rail traverse system. While some dredge makers claim full pumping rates when their dredges move backwards, few if any achieve 100% efficient dredge operation in reverse.
Significant cost savings. With an average repositioning time of 57 minutes (without the Crisafulli Pivoting Traverse System), an average dredging speed of 7 feet per minute, in a pond 400’ long and 400’ wide, with an auger cutting width of 7.5 feet, time spent repositioning between each forward pass would total 57 minutes without the PTS vs. 1 minute with the PTS. Total time to dredge the 400 x 400 foot pond would be reduced from 102 hours to 52 hours. With an assumed hourly operating cost (operator only) of $30, the PTS can save our customer with a Crisafulli FLUMP model F04D $1,497 dredging one pond once, resulting in a pretax return on investment in the PTS of 12%. The PTS achieves a much larger savings ($3,743) and higher ROI (30%) on the smaller ST-3 FLUMP. To compute a customer’s total annual savings, multiply that savings by the size of the customer’s ponds and the number of times each year the customer must dredge your ponds. A monthly dredging frequency would result in an annual cost savings of $8,213 with the larger, faster FLUMP or Rotomite and an annual cost savings of $44,914 with the smallest FLUMP. The ROI on the cost of the Pivoting Traverse System would range between 66% and 359%. See below for assumptions and calculations.
For new or existing FLUMPs and Rotomites. Crisafulli can provide the Pivoting Traverse System with new FLUMPs and Rotomites or retrofit the PTS to existing FLUMPs or Rotomites.
