Description
Precision Series rotary nozzles are based on the design of the world’s leading geared sprinkler for golf applications and feature a proven gear drive that provides wind-resistant patterns with multiple streams and multiple discharge angles.
Features & advantages
Gearbox
Rotates the nozzle with a proven planetary gearbox, a variable stator and a turbine.
WFewer models
Only two nozzles with external threads and two nozzles with internal threads are required to cover a throw range of 4.3 to 8 m and a sector range of 45-360°.
Coordinated irrigation volume = 14 mm/h (0.55 inch/h) (14 mm/h)
These nozzles supply water more slowly and evenly than normal spray nozzles. Irrigation rate of 0.55 inches/h (14 mm/h) prevents excessively long run times, which are often set in the irrigation window.
Consistent rotation speed
The drive gearbox delivers a constant rotational speed regardless of the system pressure and prevents the product from switching off at low pressure.
Technical specifications
- Throwing distance: 4.3 to 7.9 m (14′-26′)
- Working pressure range: 1.4 to 5.2 bar (20 to 75 psi)
- Recommended pressure: 2.8 to 3.5 bar (40 to 50 psi)
- Flow rate: 1.4 to 14 l/min (0.17 to 3.68 GPM)
Additional functions
- 15 unique flows with different sectors
- Maximum height of 20° discharge angle to combat strong winds
- Can be screwed onto almost all spray heads and screw adapters (male and female thread)
- Pre-assembled filter for easy installation
- Throw range reduction of up to 25 % by turning the adjusting screw by 90
- Color-coded to identify adjustable or full circle
- Irrigation rate = 14 mm/h with a square formation
- Maintains irrigation volume with reduced throw distance
- Coordinated irrigation volume from 4.3 m to 7.9 m
- Coordinated irrigation volume from 1.4 bar to 5.2 bar
- Adjustable by hand or with the tool supplied
- Even rotation speed is not affected by pressure
