Center Pivot Sprinklers

Sprinkler manufacturers have developed and marketed a large number of different sprinkler technologies that produce relatively large wetted diameters at reduced pressures.Thus, center pivot operators have a greater number of sprinkler packages to meet goals of reduced wind drift, reduced energy costs and increased water application efficiency.

The goal of every sprinkler or spray nozzle package is to apply water uniformly to the soil surface where it can be used by plants to produce grain or dry matter.Some performance characteristics can affect the suitability of a package for a specific set of field conditions.

Each sprinkler is designed to operate within a range of water pressures. Tipically, impact sprinklers can be operated over a wide range of pressures than low pressure spray nozzles.

One of the more recent changes resulting from new nozzle designs is related to water application patterns.The design process sought to achieve the largest wetted diameter and lowest operating pressure combination possible.

Water Applications for Center Pivots

Today, the value of center pivots has increased even further as the tools available in the form of computer controls and sprinkler technology have reached a new plateau.

Center pivot applications have also expanded into the realm of applying not only water but also nutrientsand chemicals to the crop via fertigation and chemigation. Advances in sprinkler technology for mechanized irrigation have answered many of the previous challenges.

Today a grower can apply water and chemicals with precision uniformity and high irrigation efficiency. The improvements in irrigation efficiency, uniformity, andthe control of runoff illustrate major technological advancements.

REASONS TO RENOZZLE YOUR PIVOT SYSTEM

1. To add pressure regulators to compensate for pressure fluctuations and stabilize flowrate.
2. To replace old technology for better irrigation efficiency.
3. To improve irrigation uniformity.
4. To operate at lower pressure and save energy.
5. To improve crop yield and get a higher return per acre.
6. To adjust gallonage to match soil and crop requirements.
7. To replace worn out sprinklers and nozzles.
8. To minimize operating costs.
9. To take advantage of local power
10. To reduce runoff and solve wheel-tracking problems.
