Self-Cleaning suction filter
Prefilters are installed when additional protection is required as well as to prevent scale build-up in suction lines and pumps.
Mounted on centrifugal pump inlet to protect against impeller damage and restricted flow/cavitation.
The filter is installed submerged in water. When pumping starts, the water flows through the screen while organic material and other floating elements are accumulated at the external surface of the screen which prevents their entry to the pump and irrigation system.
The screen is cleaned by spraying water from an internal nozzle system that rotates continuously and covers the entire screen surface.
