Duplex 2" Sprinkler


Duplex Low Pressure Impact Sprinkler is constructed with a heavy cast aluminum body, brass drive arm and brass lower turning union. Features include adjustable stops for full or part circle coverage, an adjustable jet breaker for changes stream pattern and a quick change nozzle setup all supported by a 2" female standard pipe thread connection.  The Duplex is a dual port sprinkler with a secondary stream nozzle located just above the main barrel to cover close and intermediate ranges.  The Duplex is unique to most other impacts as the drive arm operates off of the secondary nozzle instead of the main barrel.  This allows to main barrel to project water and gain ultimate distance without any interruptions from a drive arm.  The Duplex Low Pressure Impact Sprinkler also has a slightly slower reversing motion than most traditional impact sprinklers and operates well at lower pressures.  Includes a set of nozzles to accommodate 42 to 174 gallons per minute and coverages up to 280 feet in diameter!
