End of Pivot Solutions

Product catalog summary

Introduction
This document provides an overview of mechanized irrigation solutions, focusing on end-of-pivot sprinklers designed by Nelson Irrigation. These innovations aim to enhance irrigation efficiency, particularly in the corners of pivot systems.

Specifications
The document details various sprinkler models, including the R55, R75, and their variants. The R55 and R55i are designed for upright and inverted mounting, respectively, and operate within a pressure range of 15-40 psi (1-2.8 bar). The R75 and R75LP models offer high uniformity and can cover distances up to 70 feet (21 meters), with pressure requirements of 40-60 psi (2.8-4.0 bar) for the R75 and 25-40 psi (1.7-2.8 bar) for the R75LP.

Performance Data
Performance metrics are provided in both U.S. and metric units, detailing flow rates and radius coverage for different nozzle sizes and pressures. The data highlights the potential to irrigate additional acres, with the R55 capable of adding up to 10 acres (4.0 ha) and the R75 up to 13 acres (5.3 ha) in full circle irrigation.

Installation and Operation
Proper installation is crucial for optimal performance. The document emphasizes the need for a minimum 6-inch drain and highlights that poor entrance conditions can diminish performance. The R55/R55i can be operated continuously or controlled via solenoids and linked control systems.
