Series 855S Throw from 18.60 to 22.90 m Electric Control
Features
• TruJectory™ trajectory adjustment from 7° to 30° for perfect nozzle trajectory adjustment, improving coverage between sprinklers and compensating for windy conditions • Part-circle and full-circle in one sprinkler. No need to stock spare parts for two different sprinklers. • Rear nozzle capability. Offers precise adjustment to meet every irrigation need. Ideal for the perimeter of sports fields. • Selectable pilot valve, requiring fewer service components and allowing multiple pressures on each site.
Additional Functions
• Performance – Excellent wetting • The 855S series' 3-nozzle configuration offers uniform distribution, nozzle flexibility, and system efficiency. • The stator is designed to maintain a constant rotation speed, providing greater reliability for the sprinklers. • The low-power solenoid of the 855S series requires less than half the amperage of other solenoids; more sprinklers can operate simultaneously, reducing cable costs. • Reliable – Always works • The Spike-Guard™ solenoid offers almost three times greater overcurrent protection and keeps the system running. • The new construction system protects the 855S series against impacts, shielding internal parts from debris entry. Easy maintenance. • The slow opening and closing mechanism of the piston valve protects the sprinkler from water hammer, thus reducing pressure surges and consequent damage to both the sprinkler and the entire system. The system has been tested for over 30 years of operation. • Lower operating costs – Improves your profits • Few components: saves time and money. • Removable stone protection screen – Easy to maintain, stops debris before it can cause damage. • The valve seat and the stainless steel communication pipe are indestructible and do not require replacement. • Durable – Built to last even in the most impervious conditions • The nozzles are equipped with a filter and jet-breaking fins and, like the secondary nozzles, eliminate the risk of blockages. A pre-filter has been added, allowing only debris that can be safely eliminated through the nozzle openings to pass. • The DuraSeal™ gasket, made in a single piece, in a single urethane casting, has the correct downstream and upstream flow load to prevent damage caused by possible debris entry. • The DebrisBuster™, by preventing debris entry, eliminates problems related to possible damage to the valve and its seat.
