The FlexRake ships fully assembled to sites without space or handling constraints, creating installation as simple as pick, place, anchor, wire and run.

When site constraints such as limited access doors, multiple floors, and handling constraints exist, the FlexRake ships fully factory-tested to be assembled on site. Duperon's simplicity of design makes reassembly a snap, with sites often accomplishing reassembly and installation in one day - sometimes using only an on-site maintenance crew.
State-of-the-art materials such as UHMW and stainless steel are utilized, eliminating corrosion. Such materials ensure the highest duty of performance, designed such that the pressures and velocities exerted by the equipment and environment will assure a long life cycle.

Duperon's use of premium efficiency Sumitomo Cyclo gear motors eliminates abrasive sliding contact. Unique rolling contact, low operating speeds and the grease-filled non-vented gearbox allow for simple maintenance schedules.
The Duperon FlexRake is simple, consisting of three basic components: a powerful drive head, durable raking device, and a rugged bar screen. This simplicity is possible through the multi-functioning action of the FlexLink. This clever patented design allows the link to function as a frame, lower sprocket, and connection point for scrapers. Additionally, this technology allows the rake to be driven by a single sprocket.

Bottom line: simplicity works when it achieves a simple cleaning mechanism with trouble-free longevity.
Patented FlexLink design creates its own frame, lower sprocket, and scraper connection point, eliminating the need for a lower sprocket and the common problems that come with it.
  • No lower sprocket means no drive shaft, drive sprockets, or bearings requiring in-channel lubrication.
  • No tracks, gaskets, seals or other close tolerances prone to wear due to grit.
  • No underwater maintenance means no divers and no dewatering… all operations performed above the deck.
Patented FlexLink™ technology effortlessly removes debris of all sizes without interruption. Instead of complex mechanisms requiring reversal of mass, proximity switches and shutdowns, the FlexRake® continually and reliably removes debris in a wide range of conditions. No alarms, no operators, no fuss.
The FlexLink design utilizes a stainless steel link system to create a frame, lower sprocket, and scraper connection point. With 33,000 lb. yield and 60,000 lb. break point, it forms a chain that is stronger and more hard-wearing than any other in the industry. That's strength where it's needed most!
