In a sprayer system, what is often called the heart of the sprayer?

• A. Sprayer pump
• B. Sprayer nozzle
• C. Sprayer gauge
• D. Sprayer filter

Answer: (A)

The pump provides the energy that moves the pesticide solution through the system; it creates and maintains the pressure that pushes liquid from the tank through hoses and out the nozzles. Because it drives both flow and pressure, it’s often called the heart of the sprayer. The nozzle is where the liquid exits and determines droplet size and spray pattern, but it relies on the pump to supply the energy. The gauge merely shows the pressure, and the filter protects against clogs by removing debris, rather than generating flow. When the pump isn’t delivering enough flow or pressure, spray quality and rate suffer, so the pump is the component you’d check first.
