FLEXRAKE FEATURES & BENEFITS - WASTEWATER

SIMPLE
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.
NO LOWER SPROCKET
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.

DESIGNED TO RUN
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.
EXCLUSIVE CHANNEL BOTTOM PLATE
Due to the "square" sprocket action of the FlexLink, the FlexRake has the unique ability to hit the base plate of the frame with a scraping, shoveling action that moves debris up the screen eliminating accumulation at the bottom of the channel.
TOUGH MATERIALS

State-of-the-art materials such as UHMW and stainless steel are used for all wetted parts, eliminating corrosion in the harsh wastewater environment. 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.  

TOUGH GEARMOTOR
Powerful drive lifts up to 1,000 lbs. 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 5 year maintenance schedules.
BEST SCREENING EFFICIENCY
Duperon's bar screen utilizes custom tear-shaped bars with a 50% screening efficiency for .25 inch bar openings, resulting in more favorable flow characteristics and less headloss. The unique tear drop shape keeps large debris on the surface of the screen for removal by scrapers. Small debris flows right through, and full penetration scrapers assure that no debris can accumulate, even on horizontal cross members.
TOUGH LINKS
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!
