Crisafulli manufactures four standard hydraulic dredge models of its portable remote controlled, automated electric powered FLUMP (floating lagoon pumper) series (3-inch stand duty, 3-inch severe duty, and 4-inch severe duty), and the diesel powered FLUMP, the RDF-75. Crisafulli will custom engineer each of its standard models to meet customers' specifications.
Crisafulli dredges use horizontal augers. FLUMP dredges operate in a cabled environment, are remote controlled, and can be partially or fully automated.
Customers use our equipment to dredge biosolids and residuals from municipal water and wastewater lagoons; dredge industrial lagoons of waste, mine tailings, sediment, or slurries; remove settled solids from ponds or lagoons without draining the ponds or taking ponds out of service; implement or manage conservation projects, including maintenance of small ponds.
The FLUMP (floating lagoon pumper) solves industrial and municipal environmental problems in a low-cost, efficient manner. The FLUMP removes settled wastes and other by-products from settling ponds or lagoons, built to prevent wastes from leaching into the water-table.
Built tough to ensure dependable service in harsh environments, Crisafulli FLUMPs are simple to operate, and easy to transport. Crisafulli’s specialists have solved liquid waste problems for more than thirty years. Call us for standard applications -- or when no standard product will solve your problem. We will work with you to produce a Crisafulli Sludge Removal System that meets the specific requirements of your application.
Use the FLUMP to clean your pond or lagoon of sludge, sediment, biosolids or residuals.
The FLUMP enables you to dramatically cut your sludge management costs
Owning a FLUMP puts you in control of your dredging schedule
The dredge operator isn’t exposed to potentially hazardous dredged materials
Engineered for performance and quiet operation
High solids dredging performance with minimum turbidity
Easily transported to multiple sites
Our traverse system allows a single operator to change the dredges pond position in under twenty minutes.
FLUMPs now come with a high speed reverse, reducing the downtime between passes
Simple to maintain
Reliable and manufactured to last
Superior after-sale support from Crisafulli worldwide
The RDF is a perfect dredge for when you don't have access to adequate power to run an electric FLUMP, and want to operate the dredge remotely.
The RDF solves industrial and municipal environmental problem in a low-cost, efficient manner. The RDF removes settled wastes and other by-products that no longer may be scattered over the countryside, but, instead, must be contained in settling ponds or lagoons, built to prevent wastes from leaching into the water-table.
Built tough to ensure dependable service in harsh environments, The RDF is simple to operate, easy to transport and can be built with HDPE pontoons, or in steel or aluminum. Crisafulli’s specialists have solved liquid waste problems for more than thirty years.
The RDF doesn't require 420V electricity
The dredge operator isn’t exposed to potentially hazardous dredged materials
Sophisticated instrumentation options measure dredging performance
High solids dredging performance with minimum turbidity
Easily transported to multiple sites
Simple to maintain
Reliable and manufactured to last
Superior after-sale support from Crisafulli worldwide
Works in the rain
Dredge depth readout on the transmitter (Optional)
Frequency hopping
Daylight visible dredge status lights can be seen from a distance; in full sunlight.
STATUS LIGHTS INDICATE * When electrical power has energized the dredge.
* When the operator has control of the dredge.
* When the dredge motors are on.
* When there is a fault.
* When the cutterhead is jammed.
The unmanned FLUMP dredge, or the Rotomite, when operated in a cabled traverse system, are positioned and moved, either manually or automatically, along a tensioned galvanized steel cable extending across the lagoon or pond. The cable is attached at either end of the lagoon or pond to a galvanized steel cable affixed to sturdy steel posts set firmly in the ground (generally in concrete foundations). This form of traverse system is built with either two or four posts. Lateral positioning of the FLUMP is either manual, or electric by shore based electric winches.
Dramatically reduces down time. Crisafulli’s unique pivoting traverse allows the entire FLUMP to pivot 180 degrees within one minute at the end of each forward dredging pass. Without the Crisafulli Pivoting Traverse, 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.
Pivot forward, and work faster.
