Description of Operation

ScreenGuard Operations ImageA coarse screen protects the finer screen from large particles and it can be periodically cleaned manually. Automatic flushing of the fine screen is activated once the pressure differential (∆P) in the filter reaches a pre-determined value. During the flushing cycle, the backflush valve opens, pressure is released from the piston and debris laden water is discharged through the backflush valve. Pressure in the hydraulic motor chamber and the dirt collector is significantly lowered causing the dirt collection nozzles to move along and rotate cleaning the whole internal screen surface. The flushing cycle takes 5 seconds. The backflush valve closes at the end of the cycle, pressure is reapplied, moving the nozzles back to their resting position and the filter is cleaned. During the whole process, water supply is uninterrupted.
