Which component in a spray system is primarily responsible for system flow?

The pump in a spray system plays a crucial role in determining the system flow, serving as the driving force that moves the liquid through the system. It generates the necessary pressure to push the fluid from the tank through the hoses and out of the nozzles. The flow rate can be adjusted based on the pump's specifications, and it is essential for achieving the desired application rate of the spray.

While other components, such as the nozzle and the tank, are important for the system's overall functionality—regulating the dispersion and storage of the fluid, respectively—they do not control the flow itself. The strainer is primarily meant to filter out debris to protect the pump and other parts but does not contribute to flow generation. Therefore, the pump is indeed the component primarily responsible for system flow in a spray system, as it manipulates both pressure and volume to ensure effective application.
