Screen (Multiple Rake Full Penetration)

Duperon was established in 1985 as a manufacturer of pumps, expanding its product line to include the patented Self-Cleaning Trashrack (1979) and the FlexRake (1995). In subsequent years, complementary product lines such as controls, conveyors, and compactors were developed in response to customer needs. Duperon Corporation continues to pride itself on the simple mechanical design of each product, as well as the solutions developed individually for customers.  

Today, Duperon Corporation is a leader in primary liquid/solids separation technology, with installations around the globe and an ever expanding range of products that are simply amazing, yet amazingly simple.
