Duperon Corporation | FlexRake Overview | The FlexRake Simple and Tough Mechanically Cleaned Barscreens

The FlexRake^{^®}

Imagine a machine so simple, it operates from an 1/8 hp motor-FLA 4.2 at .5 rpm, creating a long product life. Imagine a machine so simple, you don’t have to schedule daily lubrication. Imagine having to check motor and bearings only annually. Imagine a machine so simple that a spare parts package is included with your order. Imagine no underwater maintenance: no sprockets, bearings or tracks underwater. Imagine mounting and removal of the unit from the deck. Imagine a machine so simple that it takes only 30 minutes to remove the entire rake. Imagine it was all true. At Duperon^®, our solutions are simple.

How it Works

The unique design of the FlexLink™, which consists of 316 SSTL investment castings, allows it to become both its own frame and lower sprocket. This is possible because the FlexLink bends in only one direction, providing both flexibility and rigidity as the current forces it against the intake screen.

Differentiators
The Standard Model is typically used for stormwater, pumpstation, hydroelectric, irrigation or other applications where the debris is varied and the screen openings are coarse: 2 inches - 12 inches. Typical debris includes general refuse, aquatic vegetation, sticks, limbs, tires and drums. The scrapers are usually serrated and configured to barscreen.	The Heavy Duty Model FlexRake is used in open channel applications (such as stormwater) where debris size, volume and velocity may be unpredictable and where there are no upstream constraints such as influent pipes or pre-screening. It handles the same debris as Standard Model but utilizes heavy duty scrapers to assist in high debris loadings.

The Full Penetration Model FlexRake is typically used in wastewater or other applications where debris can accumulate or wrap around the bars. The scraper is designed to clean 3 sides of a bar. It is available in bar openings greater than .5 inch - 6 inches. If the site allows, this ships fully assembled. All components are serviceable above the deck, eliminating confined space entries. The patented Flexlink™ system flexes and pivots around large debris AND removes it. Virtually maintenance free!

The Full Penetration, Fine Screen Model FlexRake combines the rugged reliability of the Full Penetration Model with fine screen openings. Utilizing staging scrapers and stainless steel teeth that fully penetrate the bar, the Full Penetration, Fine Screen Model offers the precision technology with the ability to adapt to large debris as well. The Full Penetration, Fine Screen is available in .25 inch - .5 inch.
