i-Wob UP3

i-Wob UP3

The i-Wob is Senninger’s top-selling pivot sprinkler. It instantly and uniformly covers the entire area of its wetted circle with consistently sized droplets. This consistent droplet size maintains the sprinkler’s pattern integrity and helps prevents wind-drift and evaporation.
 

Features

• Ideal for flexible hose drops

• Low application intensity to help reduce soil compaction and runoff

• Instantaneous 360-degree application pattern

• 4 models available with diverse trajectories and droplet sizes

• Exclusive below-the-nozzle weight eliminates the need for heavier, conventional drop weights

i-Wob & Pivot Components

Magnum-Weight Magnum Weight
Helps keep the i-Wob and other pivot applicators stable on flexible hose drops. It threads securely into the bottom of the i-Wob and can remain on the applicator during nozzle changes. The weight’s UV-resistant thermoplastic construction prevents corrosion and deters metal theft due to its lack of metal parts.

 

UP3 nozzles UP3 Nozzles
UP3 Nozzles simplify renozzling. Nozzles are removed in four easy steps: simply pinch and pull to remove the nozzle; then place and click to re-install. There is no need to disassemble the sprinkler to reach the nozzle. Plus, with the UP3 design, the i-Wob base is now an integral part of the bracket.

 

Senninger Goosenecks Goosenecks
Used to increase the i-Wob’s area of coverage and position drops for precise irrigation. When combined with the Truss Rod Slings, the i-Wob can be set to hang at a precise location along the truss rod without hindrance or kinking. This reduces pattern interruption from colliding streams and allows growers to adjust sprinkler spacing.

 

PSR-&-PSR-2 Pressure Regulators
Senninger pressure regulators limit excessive and varying inlet pressures to a constant outlet pressure. The outlet pressure can be matched to a sprinkler's design pressure regardless of the inlet pressure. Pressure Regulators help maintain sprinkler pattern integrity, distribution uniformity and performance.

 

Frequently Asked Questions


Both the i-Wob and the Xi-Wob provide instantaneous, uniform coverage over their entire wetted area.

The i-Wob was made exclusively for flexible hose drops while the Xi-Wob was made for semi-rigid, steel and PE drops. However, those that prefer the Xi-Wob can also use it on flexible hose drops as long as it's installed with a drop weight like Senninger's Magnum Weight.

i-Wob & Xi-Wob Comparison Chart


Soil-Triangle Selecting the best i-Wob model for your field begins with determining your soil type.

Why Soil? Because picking the sprinkler with the farthest throw distance or just matching a plate to a crop may do you harm in the long run.

Water infiltrates soil’s pores at varying rates depending on soil texture. If application rates exceed soil infiltration rates, sealing, overwatering and runoff are likely to occur.

That’s why growers need to consider a sprinkler’s droplet size and their field’s soil texture when determining which sprinkler they need.

To find out which i-Wob model is ideal for you, find your soil type in the chart above and then locate it on the soil triangle. The black dots spread over the triangle represent droplet sizes (small, medium, large) and suggest the ideal size for different types of soils.

If your soil type falls on the far right side of the triangle, the i-Wob with the grey model is ideal for you. If your soil type falls into the lower left side of the triangle, closer to sand, then the white model is the ideal model for you.

The black and blue models are ideal for most soil types. Selecting between these two is a matter of determining if you want the low angle blue model or a standard angle black model.


Providing the largest area of instantaneous coverage possible helps reduce the impact of a sprinkler's application pattern on the soil and crop. This critical aspect of sprinkler performance is similar to the need for wide tires on farm equipment to reduce soil compaction.

The i-Wob is capable of distributing water at a rate that closely matches a soil’s infiltration rate, thus, it helps maximize irrigation efficiency and minimize erosion.

i-Wob Stream Comparison


When installing the i-Wob, Senninger recommends using two feet of reinforced flexible hose, which is critical to reducing vibration.

For optimal performance on high profile crops such as corn, i-Wobs can be spaced to the maximum factory specified spacing on the first two spans on a 7 tower 1/4 mile machine. Limit spacing to 11' ft (3.4 m) after that criteria has been met. For low-lying crops, maximum spacing can be extended further down the system. Shorter and longer machines can use the maximum recommended spacing on 25% of the total machine length.

Close Spacing with Bubblers

Texas farmers are mounting Bubblers with just 30 inch spacing between heads and maximizing their water usage with a combination of LEPA (Low Energy Precision Application) sprinklers and conservation tillage practices.
