R55VT

Product catalog summary
Overview: The document provides technical specifications and performance data for the Nelson R55VT and R55i VT sprinklers, designed for center pivot irrigation systems. These sprinklers operate effectively in low-pressure ranges of 15-60 PSI (1-4 BAR) and can irrigate up to 10 additional acres on a 1/4 mile pivot.
Specifications: The R55VT features a patented variable torque speed governing system, maintaining constant rotation speed across various nozzle sizes and pressures. It includes snap-fit nozzles, eliminating the need for retaining pins. The R55i VT is an inverted model with a green plate, designed for easier installation and debris management.
Installation and Operation: Both models require an operating pressure of 15-60 psi (1-4 bar). Poor entrance conditions can diminish performance. The R55VT is available in upright and inverted mounts, with specific requirements for drainage and nozzle security.
Performance Data: Performance data is provided in both U.S. and metric units, detailing flow rates and radius for various nozzle sizes and pressures. The data is obtained under ideal test conditions and may be affected by environmental factors such as wind and poor hydraulic entrance conditions.
Warranty and Disclaimer: The sprinklers are warranted for one year from the date of sale, covering defects in materials and workmanship under normal use. The warranty is limited to repair or replacement of defective parts, excluding liability for crop or consequential damages. The document disclaims other warranties, including merchantability and fitness for particular purposes.
Additional Information: Patent information is available at www.nicpat.com, with additional patents pending. Contact details for Nelson Irrigation Corporation and its international branches are provided for further inquiries.

The new Nelson R55VT uses a patented variable torque speed governing system that allows the plate to maintain a constant rotation speed across a broad range of nozzle sizes and pressures. This new design also incorporates snap-fit nozzles, eliminating the need for a retaining pin.
