Mechanized irrigation The LDN - Low Drift Nozzle - offers low application intensity, a consistent droplet size and a large area of coverage at low pressures.

LDN UP3™ Easy Clean Nozzle ® The Senninger LDN - Low Drift Nozzle - was the first spray nozzle providing the option to stack multiple deflector pads. This produces uniform sized droplets along the wide range of nozzle flows found on center pivots, which helps center pivot irrigators fight wind-drift and evaporative loss. The LDN’s streamlined body and durable components can handle the rigors of traveling through tall crops. By using multiple deflector pad levels, additional grooves can be added to the LDN to control water direction and droplet size while still providing a gentle, spread-out...

Pads The surfaces of the LDN pads (smooth, medium groove, deep groove) are specially designed to deliver different spray patterns and droplet sizes. Each surface is available in three basic geometries based on the desired trajectory of throw – flat (black), concave (blue) and convex (green). Stream Patterns The LDN is available with single, double or triple pads. 24 Mini Nozzles #4 - #9 24 Deep Groove Nozzles #10 - #26 Multi-Pad Design The single pad divides a flow into 24 or 33 streams and is ideal for smaller flows. As the flow and nozzle size increase along the length of the pivot,...

Part-Circle - Directional Pattern The LDN Part-Circle pad is designed to help center pivot operators reach difficult to irrigate areas near towers. It distributes water away from wheel tracks and helps minimize rutting. With a 170º spray pattern, the LDN Part-Circle binds water into 17 discreet streams at a 10º trajectory for minimum evaporative loss. It is available with nozzles #6 through #18 and can be used in conjunction with standard full circle LDNs or other Senninger sprinklers on the remainder of a machine. Note: 170º spray pattern can vary slightly based on flow and pressure....

Chemigation (corn or cotton) Options The LDN also offers chemigation pad inserts for corn or cotton. These are designed to produce an upward spray under the crop canopy to wash the underside of the leaves - where pests might hide – thereby eliminating or reducing the need for costly pesticides. To change from irrigation to chemigation mode, simply twist and unlock the deflector pad. Flip it over and twist to lock it back in place. This quick conversion eliminates the need to carry additional parts in and out of the field. Cotton Chemigation Pad and Pad Inserts: 15 - 30º upward throw Corn...

LEPA Options It provides stability on drops for a number of pivot applicators. Its unique fit technology allows the weight to fit securely onto the i-Wob, Xi-Wob, LDN, Super Spray, and even some other manufacturer’s applicators. The weight’s easy-to-install design lets it remain on the applicator during nozzle changes. The One Weight is constructed entirely of zinc alloy. It weighs approximately 0.85 lbs (0.30 kg). Drag Hose Adapter The LDN drag hose adapter can be used with a drag hose to apply water directly into the furrow. The adapter is easy to install, snapping right onto the LDN...

LDN System Assembly Mounting • The LDN can be mounted on rigid drops or flexible hose drops. Installation To maintain product warranty and maximize drop component life, refer to the diagrams below for proper installation: • When using a flexible hose, a weight is recommended. • When using The One Weight, use the internal fit technology to nest the weight onto the base of the LDN. • Conventional slip-over weights can be used with the LDN. • Mount the LDN no less than 1.5 - 9 ft (0.46 - 2.74 m) above the ground. Rigid Polyethylene Galvanized Steel Flexible Hose Pressure Regulator Location •...
