A six vane nozzle flow straightner incorporating a one-piece design of vanes then, a tapered transition phase then, an anti-turbulent section and finally, the length of metering size which is equal to 1 x the diameter. i.e. the 'length of the land' is 1d, greatly limiting the wear.
The advantages of this 'land length' have proven successful when the water has a high concentration of sand. The efficiency and water discharge rates are effected by the most minute wear on the outlet size of the nozzle. Minimal wear has been detected with this design and the materials selected. We cannot stress too strongly the advantages of an accurately designed and manufactured nozzle.
The nozzle metering diameter is moulded to within two thousandths of an inch and very often we find after years of service in heavy sand laden water, there is no discernible wear.
The Irrigation Systems Ltd Sprinkler can provide irrigation throughout the life of the crop, performing the function of larger and smaller sprinklers.
Irrigation Systems Ltd Sprinkler - the single solution to crop development.
Simply change the nozzle insert in your sprinkler according to your precipitation rate requirement. Example: A seed bed will require less water until plants become established, use a smaller nozzle at a higher pressure to create a fine spray. Increase the nozzle size as the plants develop.

Nozzle Sizes
Insert the nozzle sleeve into the jet body by hand.
The sprinkler has been developed to allow ease of use and maintenance
in the field. Using this method will ensure the sprinkler is not damaged
through excess force.
The colour coded insert of the required size (see above) should be pushed into the jet body, by hand. Tighten the body into the sprinkler using a 13mm socket until 'hand tight'. There is a moulded seat on the jet body which seals it onto the sprinkler with the minimum effort and does not depend on the sealing action of the threads for water tightness. Do not over tighten the threads. All the nozzle sizes fit tightly into the sprinkler body with a hard push.
