Robin Rotary Sprinkler – 5.0 mm Purple Nozzle #13 (13/64") – Full Circle

RK-ROBIN-5.0MM – Robin Rotary Sprinkler with 5.0 mm Purple Nozzle

The Robin sprinkler is a high-volume, low-pressure rotary sprinkler that uses a unique cam rotor to deliver eccentric (off-center) rotation. With the 5.0 mm purple nozzle — the largest in the Robin line — it delivers 3.5–5.9 GPM over a wetted diameter of 47.6–55.8 feet at pressures as low as 10 PSI. This is the highest coverage and flow option in the Robin series, with a 3/4" MNPT connection to support the flow.

Key Features & Benefits

• Eccentric cam-driven rotation — off-center rotation provides an extremely uniform and instantaneous application pattern over a large area, eliminating dry patches
• Largest wetted diameter in the Robin series (47.6–55.8 ft.) — maximum coverage per head for the widest spacing layouts, minimizing total head count and installed cost
• Highest flow rate (3.5–5.9 GPM) — delivers the most water per head in the Robin line, ideal for mature orchards, sandy soils, or high-demand field crops
• 3/4" MNPT connection — larger inlet supports the higher flow rates without restriction
• Very low pressure operation (10–28 PSI) — operates at pressures where many sprinklers cannot, significantly reducing pumping energy costs
• Low evaporative loss — fine water droplets minimize wind drift and evaporation
• Self-cleaning mechanism — internal design helps flush sand and dirt particles to prevent clogging
• Bridgeless design — eliminates dry patches caused by structural bridges in conventional heads

Ideal Applications

Overhead and under-tree irrigation for mature orchards, vineyards, nurseries, and large-scale field crops. The highest flow and coverage in the Robin series makes this nozzle the best choice for wide spacing, sandy soils, or crops with high peak water demand.
