Sprinkler heads are rated at a specific flow rate (m³/h) and pressure (bar). Generally, you are going to use sprinkler heads with the same flow rate and pressure rating throughout your system. If you assume that you are using the same sprinkler heads throughout your irrigation system, the pressure will remain the same.

For eg: The following picture represents a plot with sprinkler rated as follows.

Flow rate - 0.10 m³/h (90degree)

- 0.20 m³/h (180Degree)

Pressure - 2.4 bar

So total flow rate = (0.10 x 4) + (0.20 x 10) =2.40 m³/h

Since each head is rated at a pressure of 2.4 bar, you need to make sure that the pump delivers a pressure of 2.4 bar over your overall flow rate requirements, as the pressure remains the same throughout the system. In this example, it is 2.4 m³/h @2.4 bar.

However, do not oversize your pump. Doing so will cause the sprinkler heads to crack or create an irregular, intermittent spray pattern. Keep your pump as close to your system requirements.

Another important factor to consider when considering installing a sprinkler pump is the amount of lift required to move water from the source to your pump. The height of the elevation (called the "suction head") should be less than 6 meters. It is better to place the irrigation pump as close to the water source as possible.

In addition to considering the suction head, you'll also get to consider how far you're pumping the water to succeed in your sprinkler heads. the space during which you're pumping the water can affect the water pressure.

The power supply is a big factor to consider when connecting the pump The single-phase three-phase power supply line introduced should give our attention.

The idea here is to stay dry, out of direct sunlight, and well ventilated in order that it doesn't overheat or flood.
