The Sime Hidra is a double-nozzle impact gun for medium-low flow irrigation, pairing a 1½ inch female connection with a 25° trajectory. Designed for solid set systems and hose reel machines, it provides a larger connection and nozzle range than the smaller K1 and Jolly models.
Coverage choice: Select Full Circle (FC) or Part Circle (PC) to suit the irrigation layout.
Durability-focused range: Sime prioritises durable materials such as aluminium and brass in its large impact sprinkler range.

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
Solid set systems and compatible hose reel installations needing a double-nozzle impact gun.
