It can be used in conjunction with a higher volume Big Gun sprinkler or on its own. The R55A is to be mounted in an upright position at the end of the overhang.
It can always remain on, turn on via a solenoid on an 800 series valve or work under the logic of a linked control system with a SR100/800P valve or SRNV100 (nozzle valve).
This part-circle, multi-stream sprinkler operates under the same principles of other Rotator sprinklers. The R55A has a braking mechanism that controls the rotation of the sprinkler plate.
The highly engineered plate geometry turns the water flow into multiple streams. Optimized wind-fighting droplets project out far, while gentler droplets fall in near, filling in the water pattern.
Water hitting the plate drives the rotation while the rotator brake maintains a uniform speed. Possibilities abound as irrigators around the world see this new end of system advancement.
Performance is 40-50 feet at 15-30 PSI (1.0-2.1 bar). Typical added acreage on a ¼-mile pivot is 6-8 acres (2.4-3.2 ha) irrigating full circle and 5-6 acres (2.0-2.4 ha) corners only. FG
