What are low pressure irrigation sprinklers and what are they useful for?


Low pressure irrigation sprinklers are a solution to hydrate plantations, especially in plots that are not too large, so if you have an area of reduced dimensions, this is the most suitable solution for your interests.

Sprinklers are those devices capable of emitting water at different pressures, depending on the model, spraying it by means of an arm with one or more outlets, called nozzles, which reach different distances depending on the variety purchased.

Thus, we can find on the market sprinklers of higher pressure irrigation that can cover the ground by rotating on itself up to 360 degrees. Therefore, they can be divided into the following types according to the force with which they disperse the water:

  • Cannons: with a pressure exceeding 7 kg/cm2, they can reach up to 50 meters.
  • High pressure: they have a pressure of around 5 kg/cm2, which results in a radius of action of between 16 and 20 meters.
  • Medium pressure: between 3 and 4 kg/cm2 can be achieved, which translates into a range of 10 to 16 meters around it.
  • Low pressure: they are the lowest alternative in the category, with between 1 and 2 kg/cm2, so they can disperse water up to 10 meters.

This is the modality we are going to deal with in this post, so that you understand what its mechanism consists of and what its models are useful for.

What are low pressure irrigation sprinklers?

Low-pressure irrigation sprinklers grew in Spain due to the increase in energy costs.


The high pressure of sprinklers is one of the main headaches for farmers, as it is one of the most important items in terms of periodic disbursement.
Therefore, many of the members of this group have chosen to reduce the pressure of the nozzles in order to reduce some of the bills they have to face.


Although it is one of the most effective measures to save part of the cost, the truth is that, like so many other things, it also has some drawbacks.

  1. The most important, undoubtedly, is the reduced range of these elements, as well as a reduction in rainfall and less uniform irrigation.
  2. By reducing the pressure, the water distribution takes on a doughnut shape due to less water spreading in the first few meters but more in the farther areas.
  3. All this leads to the need toinstall a greater number of nozzles along the length and width of the area to be irrigated in order to solve these problems.
  4. Another solution would be to mechanically break the water stream to try to achieve a more uniform irrigation at each location on the plot.

For which locations is it most convenient to use these systems?

Low pressure irrigation sprinklers, as we have mentioned, are the best alternative for small plots, where it is not necessary to cover a large area to keep soils and plantations hydrated.

By means of a not too high pressure for the emission of the jet, it is possible to reach most or all of the surface. In addition to this type of environment, they are also perfectly adapted to low crops, since the effect of this irrigation system reduces evaporation and the effect of the wind. For example, banana trees, nurseries, greenhouses, gardens or sub-arboreal irrigation systems often use this type of system.

Features of low pressure irrigation sprinklers

Some of the features that have increased the use of this type of solutions in recent years are the following:

  • High resistance to UV rays
  • Great durability, as it does not have to withstand high water pressures in its interior or in its nozzle.
  • It has internal tools that prevent the accumulation of dirt.
  • They can be adapted to different pressure levels, in order to achieve the correct irrigation in any case.
  • Different ranges of water outlet angles, depending on the model.
  • It incorporates an internal component that improves atomization and water reach.

Taking into account these essential aspects, it is important to highlight how important it is to install this variety of sprinklers in small plots. At Grupo Chamartín, we have a team of professionals who will help you choose the most suitable irrigation system for your operation, whether it is a large plot or a small garden, through the most recognized models on the market present in our catalog.
