Rain Bird 550 Series

Part Circle Gear Drive Golf Rotors

Rain Bird 550 series rotors provide the right coverage for tee boxes, greens and other small areas with short and medium throw range. With nozzles that offer higher flow rates, you can apply water precisely where needed in a shorter amount of time.

  • Rain Bird 550 has a radius of 28' to 49' (8.5 to 14.9 m).
  • Can handle pressures from 60 to 100 psi (4.1 to 6.9 bars).
  • Nozzle design provides superior water distribution with less sensitivity to spacing difference.
  • Solid design and construction provide a higher degree of reliability and longer life than commercial-grade products.
  • The part-circle Rain Bird 550 offers a 30 to 345º turning range.
  • Available in electric, integrated control, combined use Stopamatic/Hydraulic and Seal-A-Matic™ models.

Features

The Rain Bird 500 series rotors provide the right coverage for tee boxes, greens and other small areas with short and medium throw range. With nozzles that offer higher flow rates, you can apply water precisely where needed in a shorter amount of time.

Rain Bird® golf rotors are engineered for precise application and distribution uniformity, helping you get the most from your water source. With intelligent, easy-to-use features like a top‑serviceable design and quick full-circle/part-circle adjustments, Rain Bird golf rotors help you and your crew save time every week.

Timeless Compatibility

Timeless Compatibility™

Designed for Timeless Compatibility™ with every EAGLE® rotor manufactured since 1992, these rotors give you the flexibility to update internals without having to dig up the case, saving you even more time.

GBS25 Solenoid

Delivers 25kV surge protection and built‑in filtration for a second level of protection from debris. Eliminates the most common maintenance tasks that plague competing rotors.

Top Serviceability

With superior performance in a smaller footprint than competing rotors and an intelligent snap-ring design for quick access to serviceable components, Rain Bird rotors have long been the perfect choice for golf courses.
