WHICH NOZZLES ARE THE BEST?

There are 3 types of nozzles:

  • spray type
  • rotor type
  • rotator type

Ever since Hunter released the MP Rotator nozzles, we have been completely switched to them and do not use any other nozzles. Why, you may ask?

The thing is that spray nozzles have a rather high water consumption. For example, a spray nozzle that is supposed to water 3 meters with a 180-degree opening pours 230 liters of water in 1 hour, and a rotator with the same range and opening pours 80 liters of water in 1 hour. This means that, under equal conditions, with the same pump, pipe diameter, and so on, 3 times more sprinklers can be installed in 1 zone and, as a result, 3 times more lawn area can be watered.

The second difference is that with spray-type nozzles, one amount of water is poured out at the end of the jet (3 meters), less at 2.5 meters, even less at 2 meters, and at 1 meter, no water hits the lawn at all. That is why it is imperative that each sprinkler watered the previous one when designing, since they do not water under themselves. In the nozzles of rotators, the jet system is designed in such a way that at 3 meters, 2.5 meters, and so on, approximately the same amount of water is poured out. Rotavators do not water 30-40 cm below them, so overlap is also required. But, due to the rotators, you can achieve the effect of uniform watering of the lawn. That is, the irrigation system can be set up in such a way that, for example, 10 liters of water are poured out for each square meter of lawn.

Rotary-type nozzles hit with a single jet and work out their irrigation sector due to the fact that the sprinkler rod is rotated in the right direction. The water consumption is about the same as that of rotors, so you can design quite a few of them in one area, but there are nuances. For example, those rotors that are set to 90 degrees cannot operate in the same zone as those rotors that operate at 180 and 360 degrees. This creates additional design challenges, and it is extremely difficult to achieve uniformity of irrigation.

Rotary nozzles can water from 1.1 to 10.7 meters. This range is enough to cover 90% of the watering needs.

We use rotors only when there is a design need for the sprinkler to water 15-25 meters. Most often, these are football fields, golf courses, and other very large areas with lawns.
