Crisafulli’s FLUMP is an unmanned dredge connected by cable to an electrical power source. The FLUMP can be controlled manually by a full-time operator, or, alternatively, remotely and automatically by a part-time operator for lower labor costs and maximum solids production. Crisafulli offers four basic levels of FLUMP automation, Models M1, M2, A1, and A2. In addition, Crisafulli offers custom configurations of the control system.

Model M1 is the most basic manually controlled FLUMP. The only options are an electric traverse system and some displays.

Model M2 is similar to M1 but with the option of a radio remote controller.

Model A1 has an automated dredging sequence that enables the dredge to run through a complete cycle with no required operator control. Model A1 has an optional radio remote controller.

Model A2, a conceptual design requiring custom engineering, has the highest degree of automation with feedback loops to a programmable logic controller (PLC) for sludge density control, automated lateral position control, and slurry flow control. The fully automated FLUMP (Model A2) provides computerized control of the pump speed, and, via convenient push button control, dredge travel, working depth, and assures consistent solids density output. The operator can control the FLUMP from a control panel on-shore, or with a hand-held radio remote

Choose a fully automated FLUMP to gain labor savings and improved efficiency with computerized control of your entire dredging operation. The operator determines the desired solids density and flow-rate, enters the performance specifications into the PLC via a convenient keypad.

The automated FLUMP constantly monitors and adjusts its own operation to deliver exactly the specified output. If your FLUMP feeds a dewatering process, the automated FLUMP streamlines your operation by providing the dewatering press or centrifuge precisely the desired sludge volume, while reducing labor hours and use of costly polymers. Automate repetitive cleaning of your ponds, basins or lagoons of biosolids and residuals with Crisafulli’s automated FLUMP that delivers superior control, performance and productivity.

The FLUMP control panel shown below is mounted on a shore-based concrete pad. In the background note a FLUMP with both the integral floating discharge pipe and electrical cord visible. The FLUMP is floating in a recently constructed municipal water treatment lagoon.
