What is considered the most critical part of the spray system?

The pump is fundamental in a spray system as it is responsible for creating the pressure needed to push the pesticide or solution through the entire system, enabling it to reach the intended targets effectively. The pump's ability to generate and maintain consistent pressure directly influences the performance of the application. If the pump fails or underperforms, the whole system will be unable to operate efficiently, leading to poor distribution and coverage of the pesticide. Proper pump selection and maintenance are crucial for ensuring that the spray system operates effectively and achieves the desired results in pest control applications. Other components, while important, depend on the pump's functionality for overall effectiveness.
