The Sime Duplex is a medium-flow impact gun with a secondary-nozzle-driven arm. Its part-circle design incorporates a floating deflector for slow reverse, while a full-circle version is also available. A 2 inch female connection and 25° trajectory suit solid set systems and compatible hose reel machines.
Key Features

Performance depends on nozzle selection and pressure at the sprinkler. Manufacturer data assumes calm conditions, a correctly inclined jet and minimal jet-breaker interference; allow a 5–7% tolerance in flow and throw. Nozzle combinations shown are performance references, not additional product variants or a statement of included nozzles. Confirm the supplied nozzle configuration for ordering.
Ideal For
Medium-flow solid set irrigation and compatible hose reel systems, including part-circle applications requiring slow reverse.
