Big Rain Gun

A rain gun is a large sprinkler with a big nozzle that throws water a long distance and covers a wide area in each turn. It is used on large fields, fodder and cereals, on hose-reel irrigators or on fixed stands.

Because a rain gun needs a high flow and pressure, the choice depends on the pump and main line. The PE main pipe and its pressure class must be chosen for the rain gun's flow and pressure.

Our rows cover rain guns with 1-1/2, 2, 2-1/2 and 3 inch inlets. The throw radius depends on the nozzle and pressure, and our catalogue sets it per project.

In your enquiry give the inlet size, pump flow and pressure, the irrigated area and the mounting (fixed stand or hose reel) so a suitable model and nozzle are offered. Add the stand, pipe and line fittings to the same list.

A rain gun needs a steady pressure and flow to throw water to its design radius; lower pressure makes large drops and a short throw, while higher pressure makes fine drops that drift in the wind. A pressure gauge next to the gun inlet helps you control the working pressure.

In strong wind some water is carried off the field; irrigate in low-wind hours. Set the rotation angle and spray sector so roads, buildings and electrical equipment do not get wet.

The gun stand must be firm and level, because the reaction force of the jet is large. Connect the gun to the main with parts of a matching pressure class.
