Metal Agricultural Rain Guns, 1.5–2.5 Inch Inlet Options

Choose a metal rain gun by inlet size and the water demand of the field zone, with three distinct connection options.

Choose the right configuration

The 1.5-inch option is listed at 7–9 m³/h, the 2-inch option at 17–20 m³/h, and the 2.5-inch option at 30–35 m³/h. These are separate sizes, not adapters included with one gun.

Watering and connection details

• Inlet options: 1.5 / 2 / 2.5 inch, internal thread
• Working pressure range: 0.3-0.5 MPa
• Rated flow range: 7-35 m³/h
• Listed spray radius range: 23-40 m

Plan a dependable watering zone

Check pressure at the sprinkler while the zone is running. Pipe length, fittings and elevation reduce the pressure available at the head. Add the flow demand of all heads operating together and check that the supply can maintain the required pressure.

Spray radius is the reach from the head, rather than a recommended spacing between heads. Arrange overlapping patterns and assess the result in the growing area, allowing for wind and mounting height. Set watering time from the soil and crop needs after checking actual coverage.

Installation and everyday care

Use a securely supported riser and a compatible connection. Flush debris from the supply before attaching the head, then check the inlet joint for leaks during the first run. Keep the moving assembly clear of nearby supports or foliage.

If rotation or spray coverage changes, isolate the water supply before inspecting the outlets and moving parts. Confirm the chosen nozzle and connection before replacing a head, because similar-looking sprinklers can have different flow requirements.
