Irrigation Pumps

Volute pumps are widely used in irrigation. They are of simple construction, the only moving parts being the impeller and shaft. The impeller is housed in a casing (volute). The volute pump most often used for irrigation purposes is the (radial-flowcentrifugal pump.

End users should determine the amount of water to be applied during the peak period by multiplying the size of the field by the amount of water in inches that must be applied. The result is then converted to gallons per minute (gpm), and this number determines the size of the pump.

How long do irrigation pumps last? Generally speaking, the life expectancy of a sprinkler system is about 20 years, on average. As for its components taken separately, good quality heads will last you anywhere between 10 to 15 years, while inexpensive ones will only be good for 2 or 3 years.

At different pressures, the sprinkler head and nozzle will consume different amounts of water. For example, at 35 pounds per square inch (PSI) the 5000 Series Rotor using the 3.0 nozzle will use 3.11 gallons per minute (GPM). If your home’s water capacity was 10 GPM, you could place 3 heads per zone. Does a sprinkler pump need a pressure tank? Yes, the pump for the irrigation system needs a pressure tank. The pump relies on system pressure to start and stop. The system pressure in turn is mostly governed by the size of the air cushion in the pressure tank. As the air cushion expands as water is used, the pressure goes down.

Is irrigation water safe to play in? While numerous screens and some filters help keep debris, and even bugs, out of our irrigation pipes and sprinklers, the water is not considered safe for human or pet consumption. … They also remind citizens not to let their children or pets play in irrigation water as well.
