Internally rotary drum screen description

The Internally Fed Rotary Drum Screen utilizes a direct drive system to eliminate the use of belts, chains or sprockets.

A combination of stainless-steel shoes and UHMW polyethylene wear strips replace the use of trunnion wheels reducing labor intensive maintenance.

The screening panels remove easily for regular cleaning and to allow access inside the drum without disassembling the machine.

Screening panels are available in wedge wire, perforated plate and wire mesh in various opening sizes to optimize debris removal.

Internally rotary drum screen function

Internally fed rotary drum screen utilizes the internal surface of a wedge wire, perforated, or a wire mesh drum screen.

Wastewater is pumped inside the screen and the flow is distributed equally to the internal surface by the help of a distribution weir.

While the wastewater flows through, the solid waste gets stuck on the internal screen surface.

Screenings get drained as they move up and then discharged at the top of the drum screen into a conveyor with the help of a pressured nozzle system located on the outer side.

Internally rotary drum screen feature

Long product life

The unique design eliminates the need for trunnion wheels, sprockets and chains, which reduces the wear and tear points and increases the product’s lifespan.

Trouble-free maintenance

All routine maintenance is done at chest level. Removal of the drum is not required to perform maintenance and manual clean in place (CIP).

Designed for duty

Engineered to perform in fine screening applications that have high flows and high solids loading.

Flexible design

Quick change-out screening panels available in various opening sizes, allows for improved debris management.

Low cost of ownership

With few wear parts, a fractional horsepower motor and minimal maintenance required, Duperon equipment is easy to install, own, and operate.

Customizable

The water inlet can be designed on either side of the drum screen, providing options for difficult installation scenarios.
