Self-cleaning filter systems are used to filter surface water. They are often used as a safety feature of an installation as well as pre-filters for water intake. They can be used to remove organic and inorganic materials. The filters contain a stack of grooved plastic discs mounted on 4 perimetric shafts.

Installation of Self-Cleaning intake screen filter to prevent large particles such as sticks, algae, fish, and other organics from entering the pump and causing damage. The screen is installed in the water at the end of the suction line, below the foot valve.
Self-cleaning models offer a pressurized backwash line (supplied by the pump) with internal nozzles that rotate the screen to continuously clean the screen and therefore reduce maintenance.
