1" Part Circle Mini Rain Gun - 7.3-34.3 GPM - Spring Arm Impact

RK-47 - 1" Part Circle Mini Rain Gun Sprinkler

The IrrigationKing RK-47 is a compact mini rain gun that delivers the long-throw performance of larger rain guns in a smaller 1" package. With flow rates from 7.3 to 34.3 GPM and a throw radius of 39.5 to 69 feet, it fills the gap between standard impact sprinklers and full-size rain guns - ideal for smaller fields, nurseries, orchards, and pastures where you need more reach than a standard sprinkler but less volume than a large cannon.

Key Features and Benefits

• 7.3-34.3 GPM flow range - Lower flow requirement means it works with smaller pumps and supply lines compared to larger rain guns
• 39.5-69 ft. throw radius - Long-range coverage from a compact 1" sprinkler reduces the number of positions needed
• 15-60 PSI operating pressure - Wide pressure range accommodates varying pump capacities and system designs
• Full circle and part circle operation - Switch between modes without tools to handle open field and edge-of-field coverage
• 28° trajectory - Balanced angle provides good distance while managing wind drift
• Jet breaker screw - Adjusts the water stream from heavy droplets to fine spray to match soil type and crop sensitivity
• Interchangeable nozzle set included - (6, 8, 10 mm) x 3.5 mm nozzles ship with the sprinkler for immediate field use
