Effluent Rain Guns

The main reasons to use a rain gun include:

  1. Can handle up to 170,000 litres per hour.
  2. Can cover a larger area very quickly.
  3. Can achieve any application rate as low as 5 to 8mm per hour.
  4. Least likely to block out of any sprinkler/irrigator, making them useful for systems with high concentration of solids.
Midwest Machinery sells the SIME brand of rain guns, which are made in Italy. These are high pressure, high volume guns that are designed to stand up to New Zealand farming conditions. They are durable and robust, ensuring a long service life and are ideal for spreading dairy effluent on land where the contour is unsuitable for travelling irrigators, or when you need to pump large volumes in a hurry.


  • Suitable for Dairy Effluent and water irrigation
  • Wide range of volumes and application rates
  • Simple to set and adjust
  • High quality materials and construction
  • Pressure gauge
  • Counter weight

SIME Rain Gun models include the Synkro and Ranger. They come with a towable galvanised sledge making it simple to move from paddock to paddock.
