What is the primary function of pumps in irrigation systems?

• A. Moving water to sprinkler heads
• B. Regulating water chemistry
• C. Filtering debris from water
• D. Measuring soil moisture

Answer: (A)

Pumps in irrigation systems are used to move water from a source to the zones and to create the pressure needed to push water through the pipes to the sprinkler heads. They overcome friction losses in the piping and any elevation differences so the water reaches all zones with adequate flow and reach. The pump’s job is not to regulate water chemistry, filter debris, or measure soil moisture—those are handled by chemical feeders, filters, and sensors/controllers, respectively. In short, the pump’s primary role is to move water and establish the pressure required for proper distribution to the sprinkler heads.
