Center pivot irrigation sprinklers use nozzles (fixed orifices) to precisely set the water flow rate at each sprinkler location along the length of a center pivot. As the sprinkler locations move farther away from the center point, the water flow rate increases due to the larger area covered by positions farther from the center point. For example, the last sprinkler on a 1,300’ center pivot covers an area that is over 28 times larger than a sprinkler at 50’ from the center point.
Sprinkler manufacturers offer 45 different nozzle sizes to meet the flow rate requirements on center pivot machines. The nozzle diameter range begins with the smallest at 0.0625” (8/128”) and increments in 0.0078” (1/128”) up to the largest at 0.4063” (52/128”). When describing the nozzle orifice diameter it is common to use the nozzle numerator. For Valley and Nelson® sprinkler brands, a #15 nozzle refers to a 15/128” nozzle orifice diameter. Senninger sprinklers use 64ths to describe their nozzle orifice diameters. A #7 nozzle is equivalent to 7/64”. The Senninger® brand also uses “half sizes” to describe the full range of nozzles. A #7.5 refers to a 7.5/64” (15/128”) orifice diameter. Sprinkler manufacturers also use various colors and shapes to make nozzle identification easy and quick for sprinkler package assembly and field modifications.
Earlier this year, Senninger Irrigation released a new sprinkler product line, UP3 (Universal Pivot Products Platform). A feature of this sprinkler series is an easy clean, easy change nozzle design.
To remove the nozzle you pinch and pull.
Place and press until you hear a click to reinstall the nozzle.
The nozzle is installed from the side of the sprinkler, eliminating sprinkler disassembly.
