What Is a Backpack Pump Sprayer and How Does It Work?

A backpack pump sprayer is a portable sprayer designed to be worn on the back, allowing for the efficient application of liquids such as pesticides, herbicides, fertilizers, or disinfectants. It typically consists of a tank, a pump mechanism, a hose, and a nozzle, enabling users to distribute substances over a wide area with minimal effort.
