SPRINKLER NOZZLE IMPACT S204024H S20 4.0X2.4MM MI-20MM NORMA 100723447

This is a full-circle impact (impulse) sprinkler with a 20 mm BSP male thread and a dual bayonet nozzle (1/4-turn clip connection, 25° trajectory). Screw the sprinkler onto a 20 mm BSP female riser or stand, using thread tape on the male thread, so the sprinkler sits vertical and clear of the ground for full rotation. Fit the required bayonet nozzles by pushing them on and giving a quarter turn to lock. Operate at around 210 kPa; at this pressure the sprinkler wets a radius of about 14.4 m and delivers about 14.5 L/min. For solid-set irrigation, space sprinklers and risers so their wetted circles overlap for even coverage. Check the drive arm swings freely before and during operation. Tips: Keep the nozzles and swing arm clear of grit — dirty or worn nozzles reduce radius and distribution uniformity. Make sure supply pressure and flow are adequate for the number of sprinklers running at once. Store the Delrin body out of prolonged UV when not in use to extend its life.
