FLUMP Sludge Removal System

The FLUMP (floating lagoon pumper) solves a growing industrial and municipal environmental problem in a low-cost, efficient manner – i.e., the removal of 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 that are built to prevent wastes from leaching into the water-table. Customers (see above) also use the FLUMP Sludge Removal System (FLUMP) in a wide variety of dredging applications unrelated to environmental compliance issues.

Crisafulli has evolved and perfected its FLUMP over more than twenty years. More than 167 municipal, industrial, contractor and agricultural customers throughout the United States and abroad own more than 189 FLUMPs.

The FLUMP is an integrated system comprised of major standard and optional components – i.e., flotation system, primary and secondary motors, hydraulic and electrical systems, cutterhead, pump, ladder, manual or programmable  computerized controls, cabled traverse system, Pivoting Traverse System, and Crisafulli Integral Floating Discharge System – collectively referred to as the FLUMP, many of which are discussed in this Web site.

Built tough to ensure dependable service in harsh environments, Crisafulli FLUMPs are simple to operate, easy to transport and are fabricated in a variety of materials, including special metals for abrasive or corrosive sludge. 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.

The FLUMP is the small dredge that’s big on performance. It’s priced right for today’s tight budgets. We build three models of the FLUMP (3” Standard Duty, 3” Severe Duty, and 4” Severe Duty), all powered with electric motors – 15 HP to 150 HP - with various cutterheads, control systems, dredging and pumping capacities, and standard dredging depths to 12 feet. (Custom depths to 30 feet) Use the FLUMP to clean your pond or lagoon of sludge, sediment, biosolids or residuals.

        The world's most productive small dredges: discharge pump sizes 3" and  4"

When used with Crisafulli's patented Pivoting Traverse System, the FLUMP is approximately 48% more productive than competitive products. It can complete lagoon dredging projects in approximately half the time and save owners the entire cost of the FLUMP over several years from reduced operating costs.
