Hydraulic Motor Helical Scan Automatic Self Cleaning Irrigation Filter

Product structure

Principle descriptions

        The water flows through the primary screen firstly to filter out large particles then flow through finer screen.The particls are retained on the inside of the screen of the filter element. The filtered water then flows out through the outlet.

      When the pressure differential increases to the pre-determined level, the flushing cycle starts.  A automatic valve is opened on the drainage outlet then hydraulic piston release pressure.

Hydraulic motor activate suck scanner system which generates an helical movement along the screen to vacuum up the captures particles from the screen.  The captured solids are expelled through the drain valve.

    Filters continue to supply filtered water even during the flushing cycle.The whole working system is controlled by a smart box which has several control modes: pressure differential, time, manual or PLC.

Installation and connection 

Please keep the drain valve’s outlet direction horizontal position or down position to ensure the sewage is discharged completely.(More filters in parallel could get bigger flow)
