Pivots are fitted with various sprinkler packages, mounted on the top of the span or on drop-tubes (droplets), which can be galvanized or PVC or polyethylene tubes, to accommodate crop, wind and field conditions. A sprinkler package is designed for a specific operating pressure, which is usually specified at the pivot point.

Sprinkler arrangements/types (see pictures):

1. Small agricultural/ impact sprinklers near the pivot point, medium sized near the middle of the lateral and large type sprinklers at the outer end of the lateral.

2. All medium size agricultural/impact sprinklers with a variation in nozzle sizes and sprinkler spacing along the lateral with the smallest nozzles at the outer end of the lateral.

1. Low pressure spray sprinklers with fixed or rotating pad, equipped with pressure regulators (see picture) (new generation-Nelson). There are four different types: Rotators, Spinners, Nutators and Sprayers (see picture).

2. Dual sprinkler setup with dual nozzle system (see picture), allowing quick and accurate changes of system flow rate during germination and later stages of the crop's growth.

All spray nozzles are coloured to distinguish nozzle sizes. There are specific nozzles for waste water applications.

The sprayers can have pressure regulators (see picture) in order to fix a varying inlet pressure to a set outlet pressure, regardless of changes in the system pressure due to hydraulic conditions and to improve application uniformity (5 - 50 psi). The pivot sprinkler pressures are often set at 20 psi (1.38 bar).

Today's sprinkler packages offer better water management, fertiliser application and/or pesticide control. Selecting the right application package will reduce energy cost, save water, increase productivity and profitability.
