Manage your system without ever having to remove a nozzle
At the heart of the 3030 Series is the new 3NV Nozzle. Built with the precision accuracy of the 3TN, this innovative dial-nozzle combines multiple functions so you can “micromanage” your system.
- * Quick-change — push & turn, audible “click”
- * Stainless steel spring for accurate and secure positioning
- * Covers complete nozzle range, using the same numbering and flow rates as the 3TN Nozzle System
- * Same color-codes as 3TN but oddsize nozzles have weather-enduring scalloped edge
The 3NV nozzle fits all existing sprinkler types: Rotator, Spinner, Accelerator, Sprayhead, Orbitor, Part Circle. Maximize efficiency with the Square Thread fitting.
Gain Lots, Give up Nothing.
- * SUPERIOR FLUSHING OPTIONS: Sequence to work debris through. It's never advised to stick something in a nozzle – the 3NV flushes with a quick and simple turn of the nozzle. No tools necessary.
- * 'ON' AND 'OFF' CAN BE SELECTIVE: If you're overwatering, or if you need to conserve water for a time, simply select the sprinklers you want to turn off. Consider the cost savings of having a built-in ball valve on every sprinkler!

SPRINKLER PACKAGE INSTALLATION ENHANCEMENTS
- * Maximize efficiency & accuracy - install sprinklers, then walk the line and install nozzles.
- * Lugs on end of nozzle are sized & shaped to allow only correct installation and removal.
- * Visually identify sprinkler modes for quality assurance.
- * Use flush function as needed depending on water quality.
... or seamless integration into existing systems.
COST & TIME SAVING
- * To gain the benefits of the new 3030 Series you simply need a new Nozzle & Body. Existing 3000 Series Cap, Plate, Regulator & Fittings integrate entirely. (NOTE: Orbitor weight can be re-used but need new body/plate.)
- * Since On, Off & Flush functions all take place without removing the nozzle, no more dropped or lost nozzles in the field!
- * A 3NV Dual Nozzle clip (with Hi-Flo, Lo-Flo differentiation) helps farmers adapt to differing watering needs (such as crop establishment, chemigation or lowering water tables).
R3030 ROTATOR®
PROTECTIVE SHIELD PROVIDES LONGER WEAR LIFE AND ENHANCED RELIABILITY.
VERSATILE MODULAR DESIGN
Because no one sprinkler is right for all conditions, the 3030 Series features modular design components which are easily changed with a simple push and turn. You may want to start out the season with one configuration and change to a different one later.
FEATURES & BENEFITS
GREATER THROW RADIUS
Nelson's Pivot Rotator® features the greatest throw distance available on drop tubes. As a rotating type sprinkler the Rotator® produces a wider pattern resulting in a lower application rate, reduced runoff and longer soak time.
REDUCED WIND DRIFT AND EVAPORATIVE LOSS
The Rotator® more than meets the challenge of putting a rotating-type sprinkler on drop tubes — down out of the wind — to minimize wind drift and evaporative loss.
COLOR-CODED NOZZLES
The 3NV Nozzle system is at the center of the 3030 Series Pivot Product line with easy-to-identify, wear-resistant, precision-accurate nozzles. This innovative dial-nozzle combines multiple functions so you can 'micro-manage' your system. PRESS, SPIN, CLICK between 'on', 'off', 'flush' and 'line flush' functions.
- * Careful selection of pressure and sprinkler configuration must be taken into account to optimize droplet size.
- ** Pressure limits may exist on minimum and maximum nozzle sizes.
- *** Throw Distance Varies with Pressure, Nozzle Size, Mounting Height and Hydraulic Conditions.

IMPORTANT MOUNTING INFORMATION:
- 1) The Orbitor requires a minimum of 2' (0.6 m) of reinforced flexible hose in the mounting assembly.
- 2) When using the Orbitor with the weighted cover, do not use any other conventional weight styles instead of, or in addition to, the Orbitor weight.
- 3) When using the Orbitor with the plastic cover, an inline weight is required.Use Nelson Slim Weights (page 25) or 3/4” NPT threaded weights. Slip weights require the Nelson Clamp Saver.
- 4) Always be sure that the Orbitor Weight, Slim Weight, or threaded weight is securely tightened.
- 5) Always be sure that all components in the mounting assembly and the Orbitor are securely tightened. Use new* Nelson pressure regulators and fittings.
- 6) If ¾” ball valves are used, use metal nipples or Nelson P/N-12291 plastic nipples.
- * New, patented single-strut seat manufactured after 2007.
UNDERSTANDING APPLICATION RATES
WITH SUPERIMPOSED APPLICATION RATES FOR CENTER PIVOT SPRINKLERS, IT IS OBVIOUS THAT THE ROTATOR®, WHICH PROVIDES THE WIDEST THROW DISTANCE ON DROP TUBES, COMES THE CLOSEST TO MATCHING INFILTRATION RATES OF THE SOIL. THE BEST CONDITION FOR INFILTRATION IS TO KEEP THE SOIL SURFACE OPEN AND APPLY WATER USING A WIDE APPLICATION WIDTH.
WITHOUT SPRINKLER PERFORMANCE THAT CAN APPLY WATER AT AN APPLICATION RATE THAT MORE CLOSELY MATCHES THE INFILTRATION RATE OF THE SOIL, THE EFFICIENCY GAINED WITH DROPS — AND MONEY SAVED WITH LOW PRESSURE — IS SOON LOST TO RUNOFF.
Average application rate (AAR) is the rate of water application over the wetted area. It is an average value assuming uniformity within the wetted area. Pivot average application rates increase with the higher flow demands required at the outer portion of a center pivot. Comparably, in analyzing different sprinkler options, superior throw distance yields lower average application rates.
PRECISION IRRIGATION — BEGINNING TO END
DO YOUR DUE DILIGENCE
An accurate nozzle chart is essential to center pivot irrigation. Nelson has developed a highly-sophisticated design tool for dealers and distributors to determine nozzle sizing after entering system specs and selecting pivot spans, fittings, sprinklers and regulators. Irrigating in a circle is complex-make sure you use the necessary tools to get the job done right the first time.
PERFORMANCE DATA
The nozzle sizing system is based on 128th inch increments, e.g. 3TN/3NV Nozzle #26 has an orifice diameter of 26/128th inches while 3TN/3NV Nozzle #27 has an orifice diameter of 27/128th inches. For 3TN Nozzles, the odd-numbered nozzles have a color box around the number marking. This color box denotes the color of the next larger nozzle size. The odd-numbered 3NV Nozzles have a scalloped edge rather than secondary coloring.
This flow data was obtained under ideal test conditions and may be adversely affected by poor hydraulic entrance conditions, turbulence or other factors.
Nelson Irrigation makes no representation regarding sprinkler flow rate accuracy under various plumbing and drop pipe conditions.

PRECISION ACCURACY IN TOUGH FIELD ENVIRONMENTS
THE FUNCTION OF A PRESSURE REGULATOR IN CENTER PIVOT SPRINKLER DESIGN IS TO FIX A VARYING INLET PRESSURE TO A SET OUTLET PRESSURE, REGARDLESS OF CHANGES IN THE SYSTEM PRESSURE DUE TO HYDRAULIC CONDITIONS, ELEVATION CHANGES AND PUMPING SCENARIOS.
THE BENEFITS INCLUDE A UNIFORM DEPTH OF WATER APPLICATION, CONTROLLED SPRINKLER PERFORMANCE (DROPLET SIZE AND THROW DISTANCE), AND FLEXIBILITY IN SYSTEM OPERATION.
PERFORMANCE DATA
The Nelson Universal Pressure Regulator has a flow up to 12 GPM (2.7 M3/H) at 15 PSI (1.0 BAR) and above.
HOW MUCH ELEVATION CHANGE IS ACCEPTABLE? LESS THAN 10% FLOW VARIATION IS A GOOD RULE OF THUMB
This graph is based on the elevation limit which will cause a flow variation of ten percent or more. If the elevation change from the lowest point is above the line then a flow variation of more than 10 percent will occur. Notice the lower design pressure allows less elevation change before pressure regulators are recommended.
NOTE: Even if elevation changes do not require pressure regulators, you should consider them for their other advantages.
NOTE: Even if elevation changes do not require pressure regulators, you should consider them for their other advantages.
TECHNICAL TIPS FOR REGULATING SYSTEMS
IMPORTANT: Allow approximately 5 PSI (.35 BAR) extra pressure in order for the regulator to function properly. For example, the minimum design pressure for a 20 PSI (1.4 BAR) pressure regulator is 25 PSI (1.7 BAR).
IMPORTANT: If your system is designed with Nelson sprinklers, use Nelson Pressure Regulators. Individual manufacturers’ pressure regulator performance varies. Interchanging could result in inaccurate nozzle selection.

ADDITIONAL ACREAGE AT LOW PRESSURE
NO OTHER END OF PIVOT SPRINKLER WORKS IN THE LOW PRESSURE RANGE OF 15-60 PSI (1-4 BAR) AND PROVIDES UP TO 10 ADDITIONAL IRRIGATED ACRES (ON A 1/4 MILE PIVOT).
The R55 VT End of Pivot Sprinkler is changing the way farmers irrigate with center pivots. It can be used to pick up added acreage both throughout the full revolution of the pivot or just in the corners, depending on site specifics and irrigator preferences.
It can be used in conjunction with a higher volume Big Gun® Sprinkler – or on its own. The R55 VT (with blue plate) is to be mounted in an upright position at the end of the overhang.
The New R55i VT, with a specially engineered green plate, has been made for inverted applications. This configuration is found to be easier to plumb - and some say it’s effective in helping manage debris that collects at the end of the system. Please note that radius is typically less for the inverted, green plate than for the blue plate.

Nelson's R55VT and R75 End of Pivot Sprinklers are now even easier to add to any center pivot system with the End Sprinkler Adapter. Choose from the heavy-duty NPT or BSP threaded options. This adapter eliminates expensive fittings and is very easy to install. (Not to be used with impact sprinklers.)
A SECONDARY END GUN CAN PICK UP EXTRA ACRES BY IRRIGATING WHERE THE SR100 CAN’T – AS THE PIVOT ENTERS/EXITS THE CORNER, AND AROUND OBSTACLES SUCH AS ROADS AND BUILDINGS.

SR75
30 GPM-160 GPM (6.8 M3/H-36.3 M3/H)
WITH PROVEN DEPENDABILITY, PERFORMANCE, LONG WEAR LIFE AND REPAIRABILITY KNOWN FROM BIG GUN® SPRINKLERS, THE 18 DEGREE SR75 IS AN AFFORDABLE BIG GUN OPTION THAT PERFORMS WELL AT LOW PRESSURES.
SR100
50 GPM-300 GPM (11.4 M3/H-68.2 M3/H)
THE SR100 BIG GUN WITH AN 18 DEGREE TRAJECTORY IS THE MOST POPULAR PIVOT END GUN USED ON CENTER PIVOTS TODAY. A BIG GUN® SPRINKLER (OPERATING THROUGH A COMPLETE ROTATION) ON A QUARTER-SECTION PIVOT CAN EFFECTIVELY IRRIGATE UP TO 20 ADDITIONAL ACRES (8.1 HA). CONSIDERING THE COST EFFECTIVENESS OF PUTTING THIS ADDITIONAL LAND INTO PRODUCTION, AN END GUN OPTION SHOULDN’T BE OVERLOOKED.
Diameters are based on a 24° trajectory for the 75 and 100 Series. The lower trajectory angles result in better wind fighting ability, but reduced throw distances. Throw reduction depends upon nozzle flow rate. In general, the throw distance is reduced approximately 3% with each 3° drop in trajectory angle. Big Gun® performance data has been obtained under ideal test conditions and may be adversely affected by wind, poor hydraulic entrance conditions or other factors. Test riser height of 3 feet (0.91 meters) above measurement surface. No representation regarding droplet condition, uniformity, application rate, or suitability for a particular application is made herein. Additional nozzle options and sizes available.
