VYRSA 66 Plastic Part Circle 20mm Male Double Nozzle 30 x 11 Trajectory

The Vyrsa 66 is a high-performance, part-circle plastic impact sprinkler engineered for medium-flow agricultural irrigation applications. With a 3/4" (20mm) male BSP connection and dual-nozzle configuration, it provides reliable coverage for cereals, vegetables, alfalfa, and other broadacre crops—especially in side and corner zones of full coverage systems.

Moulded from UV-resistant plastic and fitted with stainless steel springs and shaft, the Vyrsa 66 is built to withstand challenging field conditions and exposure to aggressive fertilizers. Its internal O-rings and washers are made from stainless steel, PTFE (Teflon), and special polycarbonate for long-term durability and resistance to chemical corrosion.

The sprinkler operates with a 4.0mm main nozzle at a 30° trajectory and a 2.4mm secondary nozzle at 11°, delivering a spray diameter of 12 to 19 metres (39 to 62 ft). It works efficiently within a pressure range of 1.75 to 5 bar (25–75 PSI) and a flow rate of 800 to 3,270 L/h. The average rotation speed is approximately 25 seconds per full turn (at 3 bar with standard nozzles), providing consistent and uniform distribution.
